Adblue - Wholesale and shipment from a warehouse in Serbia

WHAT IS ADBLUE® UREA?
  The environmental standards of the European Union - Euro 4, Euro 5 and Euro 6, require a reduced content of harmful substances in the exhaust gases of trucks and similar heavy equipment. Today, there are several technologies that allow cleaning the exhaust, but more and more car manufacturers are choosing SCR technology. The essence of SCR is the injection of a special AdBlue® reagent into the exhaust gases, due to which a chemical reaction occurs and environmentally harmful nitrogen oxides NOx are decomposed into harmless water and nitrogen under the influence of high temperature. Transport companies are increasingly moving to the use of this technology, realizing the features and benefits of using an innovative reagent.
WHERE TO BUY ADBLUE® UREA?
In Europe, such a product as urea can be bought at almost all gas stations, but in Russia, far from every gas station you can find an original product and you can guarantee the high quality of the liquid only by purchasing it from dealers and wholesalers. The best option is to agree on direct deliveries from the M-Standard plant, the main activity of which is the production of AdBlue® reagent and other technical fluids, under the official license of the license of Verband der Automobilindustrie e.V. (VDA)

JLLC "M-Standard" supplies products through a network of distributors in the Republic of Belarus, the Russian Federation, Kazakhstan, Ukraine, Moldova, Georgia, Armenia, Azerbaijan, Lithuania and Latvia. On the Russian market, M-Standard products are represented in six federal districts of the Russian Federation (Siberian Federal District, Ural Federal District, Volga Federal District, Central Federal District, Northwestern Federal District, Southern Federal District).

The scheme of the current logistics coverage of the territory of the Russian Federation is shown below on the map in blue. In these regions, it is possible to purchase products at the company's regional warehouses located on the basis of official distributors.

Distributor locations are marked in red. If there is no official partner of the plant in your city yet, you can become one!

The production line is certified, and the manufactured goods undergo regular quality checks in a European laboratory accredited by the brand owner.

It is always profitable to buy products directly from the manufacturer, as they can be produced in any quantities required by the customer, in the most convenient consumer packaging. In addition, the price of such a reagent as urea is quite affordable for both wholesale and retail purchases, so this business will become a profitable investment, and the high quality of the reagent guarantees the loyalty of representatives of transport companies to dealers who purchase at the M-Standard plant .

WHY SHOULD ADBLUE® BE FAVORABLE?
Every year the consumption of AdBlue® solution is growing rapidly, as more and more transport companies switch to its use. In turn, more and more manufacturers are producing heavy trucks, in which exhaust gases are cleaned using SCR technology. On the territory of Russia, Belarus and Ukraine, the requirements of environmental standards are not so high yet, but large companies working with European supplies are clearly interested in purchasing large batches of the reagent. Buyers are attracted by the many benefits of using:
Fuel economy

Road tax cut

Environmental friendliness

AdBlue® urea optimizes engine performance, resulting in a reduction in overall fuel consumption of approximately 5%, which is significant when traveling long distances.

Transport companies whose cars regularly travel on European roads receive a discount on the payment of a mandatory European road tax, which reduces costs.

Diverse and rich experience, constant quantitative growth and the scope of our activities require us to analyze positions.

Adblue - Wholesale and shipment from a warehouse in Serbia

RW AdBlue is a technical fluid based on the highest degree of purification of a solution of urea (32.2%) in demineralized water (67.8%). The product is designed to work in selective catalytic reduction of nitrogen oxides in exhaust gases (SCR), which is necessary to achieve environmental standards Euro-4, Euro-5 and Euro-6 for the emission of harmful substances.

SPECIFICATIONS AND APPROVALS
ISO 22241-1/2/3

APPLICATION
Euro-4, Euro-5 and Euro-6 diesel engines of passenger and commercial vehicles equipped with SCR exhaust gas cleaning system

What is AdBlue?
AdBlue® is a registered trademark for the product AUS 32. AdBlue is copyrighted by the German Automotive Industry Association (VDA). AUS 32 is a solution of commercially pure urea (32.5%) in demineralized water (67.5%) and is used as an additive working fluid in diesel engines using SCR (Selective Catalytic Reduction) technology.

The use of SCR systems on diesel engines is necessary to achieve Euro 4, Euro 5 and Euro 6 emission standards.

The industry standard ISO 22241-1/2/3/4/5 has been developed to regulate the quality, circulation, transportation and storage of AdBlue.

In order to obtain the right to use the AdBlue trademark on its product, the AUS32 manufacturer must pass a technical audit of the entire chain from production to the final consumer of AdBlue. The quality of AdBlue can be checked by the owner of the AdBlue trademark (VDA) later at any time both in production and in the retail network. This distinguishes the product, which has an official AdBlue license, from all other products, the so-called "diesel urea solutions".

AdBlue fluid is produced by the largest European and Russian urea manufacturers such as Eurochem, Yara, Pulawy, BASF, Achema, etc.

What is the consumption of AdBlue urea per 100 km? How much AdBlue urea does a truck use?
As a general rule, the consumption of AdBlue urea (Adblu) on a truck should be approximately 4% of the diesel fuel consumption for Euro IV, 6% for Euro V and approximately 3% for Euro VI. The AdBlue urea consumption of a truck per 100 km is approximately 1.5-2 liters. Thus, a typical truck consumes approximately 1500-2500 liters of AdBlue per year, depending on the mileage and vehicle type. With a tank of 80 liters you will drive approximately 5000 km. Do not forget about the AdBlue urea quality factor. There is a myth that supposedly it is possible to dilute AdBlue urea with water and thus

What is SCR technology
After studying and evaluating different approaches to comply with Euro IV and Euro V for heavy vehicles, the automotive industry has opted for SCR technology, which uses AdBlue as a reducing agent.

The use of SCR technology has confirmed the ability to neutralize NOx emissions, during test cycles and in operation. The combination of engines with low levels of particulate matter in the exhaust gases and the use of SCR technology to reduce nitrogen oxide concentrations, allows you to meet the requirements of EURO IV and EURO V standards.

Basically the chemical reaction of the SCR process looks like this
AdBlue is injected into the hot exhaust gas and hydrolyzed at temperatures above 180°C to form ammonia (NH3) according to the following reaction equation:

Hydrolysis reaction:
(NH2)2CO + H2O > 2NH3 + CO2

Further, the base metal of the SCR system is the catalyst for the next reaction, in which the initial forms, nitrogen and water, are formed.

SCR - reaction:
4NH3 + 4NO + O2 > 4N2 + 6H2O
8NH3 + 6NO2 > 7N2 + 12H2O

In order to maintain the efficiency of the SCR technology with aftertreatment of the exhaust gases, it is necessary to avoid contamination of the AdBlue agent with foreign substances and particles, and also not to expose the liquid to physical conditions beyond the established limits.

Factors affecting the life of the catalytic converter
The catalysts used in the SCR system consist of catalytically active transition metal compounds on ceramic crystal supports. The ability of the SCR system to convert NOx to N2 and H2O depends, to a large extent, on the activity of such active sites, and on the pore size in the crystal carriers. The pore size affects the diffusion rate of the exhaust gases in the catalytic converter.

To ensure maximum efficiency of the SCR system over a long period of time, the quality characteristics of the AdBlue fluid must be controlled very tightly, since many substances present in the AdBlue fluid, when exceeding their threshold value set by the ISO 22241-1 standard, irreversibly destroy the catalytic system, or physically blocking pores, or by deactivating active centers.

Insufficiently efficient operation of the SCR system, in case of inertia of the catalytic converter, may cause
Increase in NOx emissions
Cause engine damage due to increased exhaust gas pressure.

Rules for the storage and circulation of AdBlue (AUS32)
Use of materials compatible with AUS32 AdBlue.
All materials used in the manufacture of tanks and containers, including hoses, control fittings and fixtures for storage, transport and handling, must be compatible with the AdBlue urea solution (AUS32). Materials for samplers, sample storage tanks and canister must be compatible with the AdBlue urea solution.

Materials that can be used in direct contact with Adblue
Highly austenitic chromium-nickel steels, chromium-nickel-molybdenum steels according to DIN EN 10088-1-3 or stainless steels 304, 304L, 316, 316L.
Titanium
Polyethylene, no additives
Polypropylene, no additives
Polyisobutylene, no additives
Polyfluoroethylene (PTFE)
Polyvinylidene fluoride (PVDF)
Perfluoroethylene (PFE)
Perfluoroalkoxyalkane (PFA)
Any other materials not on the list must be tested for corrosion resistance and possible effect on the product characteristics given above.

Non-recommended materials that can NOT be used in contact with Adblue.
Materials that react with ammonia to form compounds that can adversely affect the operation of the SCR system: carbon steel, zinc coated carbon steel, mild iron
Copper, copper alloys, zinc, lead
Solders containing lead, silver, zinc or copper
Aluminium, aluminum alloys
Magnesium, magnesium alloys
Nickel-plated plastics or metals
Physical conditions during storage and transportation
To prevent deterioration of the quality of AdBlue during storage and transport, the following physical conditions must be ensured:

The recommended storage temperature is no higher than +25°C to ensure maximum shelf life.
Storage below -5°C should be avoided to prevent AdBlue from becoming solid. If the liquid freezes, it must be placed in a warm room. After the liquid has melted, it can be used again.
Keep out of direct sunlight
Maintain sealing to prevent contamination.
Long-term storage at temperatures above +30°C will lead to a hydrolysis reaction, with the formation of ammonia and an increase in pressure, and a reduction in the shelf life.
AdBlue shelf life limit
Taking into account the tendency to hydrolysis, the shelf life of the urea solution for AdBlue diesel depends on the constant temperature at which it is stored.

At a constant storage temperature of +10°, the shelf life is 36 months.
At a constant storage temperature up to +25°, the shelf life is 18 months.
At a constant storage temperature up to +30°, the shelf life is 12 months.
At a constant storage temperature of +35°, the shelf life is 6 months.
At the end of the shelf life, samples must be taken and tested to decide on the future use of the product.
Degree of purity of materials in contact with urea solution for AdBlue diesel engines
All materials in contact with AdBlue must be free from foreign matter such as oils, fuels, lubricants, solvents, dust, and any chemical or natural substances.

Prior to initial contact with AdBlue, materials must be cleaned and flushed with demineralized water (do not use tap water!) until samples of the water used for cleaning indicate that the system has been cleaned. Due to the risk of contamination, the use of detergents for cleaning is unacceptable.

The use of non-specialized equipment is not recommended.

Containers filled with AdBlue must be sealed.

Environmental protection - waste treatment and disposal
Environmental aspects regarding pollution of water and land resources
Urea solution for diesel AdBlue is classified as a substance that poses a minimal risk of pollution of water and land resources. For more information, contact the manufacturer.

Environmental aspects in relation to air pollution
AdBlue (diesel urea solution) is an aqueous urea solution. If the product maintenance instructions in this document are followed, there will be no negative impact on the atmosphere.

In case of fire, containers with AdBlue solution must be cooled with water pressure to prevent pressure build-up and explosion of containers. At elevated temperatures, AdBlue begins to rapidly decompose with the formation of ammonia and carbon dioxide.

Waste treatment and disposal
In the event of a spill or leak, the product must be collected by pumping or using absorbent materials into a suitable container and placed in a waste disposal container. The contents of such containers must be marked with a special marking to avoid mixing with the AdBlue working fluid. Discharge of waste into surface water and sewerage is unacceptable.

For information on waste disposal, contact your local authorities. Residues of AdBlue spills can be flushed down the drain with plenty of water. Recommended waste classification according to EWC (European Waste Catalogue): 06 10 99 (Fertiliser sludge - Waste, non-hazardous substance).

Waste from clean-up procedures is disposed of in a manner similar to spills and leaks.

Safety precautions when working with AdBlue
The product is classified as safe according to EU Directive 67/548/EEC. There is no information on special danger to human health and ecological danger.

Ingestion of a substance in small quantities does not pose a danger. If the product has got into the digestive organs, it is necessary to rinse the mouth and drink plenty of water. If the feeling of malaise and discomfort does not go away, you should consult a doctor.

The pH level of the AdBlue urea solution is 9.0, which can cause burns to the skin if prolonged contact or immersion of body parts in the tank with the substance. If possible, latex gloves should be used.

Although the product is not classified as an irritant chemical, direct contact with the eyes may cause short-term discomfort characterized by tearing or conjunctival redness. In case of direct contact with the solution in the eyes, they should be rinsed immediately with plenty of water and seek medical advice.

Spills should be cleaned up carefully to prevent personal injury and injury, as the spill surface becomes slippery if product leaks. Wash your hands thoroughly at the end of work and between work.

Why AdBlue is not "urea"
In the vastness of Russia, for several years now, a product has been sold, colloquially referred to as "urea". Yes, the name is not very aesthetic, but what can you do - folk word creation. Many consumers use the name UREA to refer to AdBlue diesel catalytic converter fluid. So we are talking about the same product? Or is it still not?

AdBlue diesel catalyst fluid is used in exhaust gas treatment systems for Euro 4, 5 and 6 diesel vehicles. This is a reference for the unenlightened, but this article is apparently read by people who know the "topic". Therefore, let's get straight to the point, especially since on the Internet you can find a lot of materials about the technical part of the issue.

Today is not about that.

Today, about the fundamental difference between a product called AdBlue and just "urea". It seems to be one and the same. An no.
At the very beginning (2008-2010), everything was simple, the first AdBlue suppliers appeared - the so-called "Lithuania" (Achema), then "Poland" (Pulawy). The products were excellent, if you do not take into account outright fakes. By the way, the notorious fake "sunflower" is still sold here and there.

“AdBlue Borealis (Sunflower) handmade liquid at a point of sale”
Only two problems were - the price is high, but you can not buy everywhere.

Next is more fun. The so-called "import substitution" began. For some, this is really IT, but for someone it’s just an opportunity to “fish in troubled waters.” Russian licensed AdBlue producers appeared, and along with them ten times more “imitators”. Prices have dropped and that's good. But what about quality?

By the way, everyone who has already suspected us of being biased in favor of AdBlue producers is asked not to read further. You will still think that we are “treating” you. We will present some simple considerations and facts, and you can draw your own conclusions.

Liquid for catalysts of diesel cars in the international technical regulations has the abbreviation AUS 32 (Europe and Asia) or DEF (USA) or ARLA (Brazil). This is the technical name for a 32% solution of urea in water intended for use in a diesel engine. These names do not define the quality of the product. It's just a definition of a substance with specific properties - like 95 octane gasoline, or 365/80 R20 tires.

So don't be fooled by the presence of these foreign names on cans. By themselves, these letters of trust should not be added to the product. If you see the inscription “Gasoline A95 EURO” on a plywood poster near the filling station, this does not mean that there is the same fuel as at Gazprom.

AUS32 quality requirements are set out in the international standard ISO 22241 and our GOST R ISO 22241-1-2012. Domestic producers of "urea" are very fond of referring to these standards. However, you must understand that such an inscription does not guarantee anything. By themselves, the ISO or GOST standard does not confirm the quality of a particular liquid in a store, but defines the general requirements for a product of this type, as a kind of guideline that a manufacturer must follow. But in real field conditions, none of the regulatory authorities checks the conformity of the product, and the consumer does not even have such an opportunity.

The situation is completely different with the presence of the AdBlue inscription on the canister. AdBlue is a trade mark meaning a kind of quality mark. Behind him is a guaranteed, not declared, but a real set of qualities.

Why is it so?

Because the right to use the AdBlue name on their products are only those manufacturing enterprises that have passed the audit procedure for their entire production and distribution chain. And it's not a formality at all.

The audit is carried out by an international organization - VDA (Verband der Automobilindustrie). This organization regulates quality standards in the automotive industry in Europe.

With an extremely strict audit, everything is checked: where the raw materials come from, the production itself, containers, the product quality control system, logistics, distributors, and they can even look at the end user to see how it works - pour AdBlue from a dirty bucket or use the proper equipment.

Upon obtaining a license, the manufacturer becomes a co-founder of the AdBlue trademark and is interested in the quality of his product, and monitors the quality of the product of his fellow license holders. They just control each other. Licensees value their reputation and the quality of their product. Otherwise, there is no need to obtain a license, you can do it without it, as all other manufacturers do, who care. You can’t buy a VDA license with money alone, as is often the case here in Russia.

That is, if you see a product on the shelf of a point of sale that says AdBlue, you have every reason to trust this product (of course, unless we are dealing with a fake or fraud on the part of the seller). What could be more reliable than a system where manufacturers themselves look after each other? And the consumer wins as a result. This is exactly the case with AdBlue and its quality control. No wonder all European car manufacturers recommend the use of AdBlue.

How about other products in this category?
That's just all the other products - it's "just urea", of which there are many in the vastness of Russia.

As soon as the producers of "urea" do not name their product, and D *** blue and T ** blue and A ***** blue and E **** blue ... .. The main thing is to be associated with the original -AdBlue, but with This does not bear part of the responsibility that licensed manufacturers bear.

You will say: well, it has begun, “slander”.

Let's figure it out. We cannot say unequivocally that these manufacturers make a low-quality product (this is difficult to follow, we did not check all of them). No, probably they can make and maybe even make a product of more or less normal quality. But how and by whom is this confirmed? To whom are they responsible? Can they ensure the consistent quality of their product? What raw material do they use? And most importantly - who checks them?

Quality raw materials for the production of a good quality product is crucial. This raw material can be purchased in Russia in just a few places. But agricultural fertilizers in bulk in the country. Often, it is these cheap raw materials that are used by some manufacturers of various ****BLUE. This raw material has all sorts of unwanted impurities and products made from it kill the car's catalyst over time.

Another common trick that dubious manufacturers use is to slightly underestimate the urea content of the solution. Urea is, in fact, the most expensive component of the final product. Reduced the percentage or two of urea - got a savings of 7-8 percent on the final product. Who will check?

Have you ever heard talk about the fact that for some reason one "urea" is consumed more than another? Free cheese only happens in a mousetrap.

By the way, with regard to water - the second (and very important for quality) component of the product - it is also not so simple. Water must be thoroughly purified, demineralized. Since untreated water just contains an amount of impurities, such as metals, that is unacceptable for use in diesel engines. To clean it, you need to have the appropriate equipment - high-tech and expensive. Why spend money on it? Let's pour water from the tap - consumers already "eat".

In general - draw your own conclusions! Considerations and facts we stated.

As for the difference in prices for "urea" and AdBlue. It's not all tragic. Prices are almost equal. There are certain regional nuances, but in general there is a tendency to equalize prices.

It is clear that running around outlets with flasks and a refractometer and checking the quality of "urea" is not realistic. What to do? Yes, everything is simple - to demand a guaranteed quality product in retail outlets. Don't fall for cheap scams. Only we ourselves can stimulate the market to work correctly with our choice of a quality product.

Buy AdBlue from reliable retail outlets, ask for supporting documents and you will be fine. DON'T PURSE, USE ADBLUE!

We will talk about how one AdBlue differs from another AdBlue, about manufacturers present on the market and their distinguishing features - we will talk in the next article.

What happens if you dilute AdBlue urea with water?
If you dilute AdBlue urea with water, this will not save. NO sensors at the catalyst inlet "see" how much nitrogen dioxide is contained in the exhaust gases, and based on this, the system supplies the required amount of Adblue urea solution to the catalyst, based on its standard concentration (32.5% urea), and at the outlet of the catalyst the second NO-sensor controls the efficiency of the system and the degree of gas purification.

The substance directly involved in the catalytic neutralization reaction is "urea", and water is simply the carrier of the active substance. Accordingly, if you dilute AdBlue with water, that is, reduce the concentration of urea in the solution, then the urea itself in the solution will not be enough to effectively neutralize nitrogen dioxide, the control system will see this and instruct the pump to increase the reagent supply to increase the neutralization efficiency to the specified parameters. In this way, the system will automatically increase the consumption of the already diluted AdBlue. And you won't be able to save anything. The load on the AdBlue supply pump will only increase.

Often it is the dilution of AdBlue with water that leads to an accelerated failure of the urea dosing pump!

This is about the amount of Adblue consumed. But if at the same time it is diluted with ordinary, not demineralized water, then the metal salts present in ordinary water will eventually disable the SCR system.

Is it possible to drive a truck without AdBlue urea? What happens if you drive without urea? How far can you drive without AdBlue?
When using a truck with an empty Adblue urea tank, the engine will go into the so-called "Limit-mode". The engine power will be reduced by about 30-40%, and, as a result, traction will drop and fuel consumption may slightly increase. Riding will become uncomfortable and uneconomical.

It is important to understand that the presence or absence of AdBlue does not in itself affect power or fuel consumption. The decrease in power and increase in consumption is not a consequence of the lack of urea, but the results of the engine management program, which thus prevents the long-term use of a faulty car.

How is AdBlue urea made?
There are two main methods for producing a urea solution for AdBlue diesel:
"Direct method" - this method of producing AdBlue is only possible directly at the Nitrogen Plant.
"Secondary method", or the so-called "Blending", that is, the technology of mixing granular urea with water.
AdBlue is a solution of the highest quality urea and demineralized water, mixed in proportions of 32% urea and 68% water.

Urea or urea, as a mineral raw material, is produced by large chemical enterprises - they are also called "Nitrogen Plants". In commercial form, urea exists as granules and is mainly used in agriculture as fertilizers, as well as in the chemical industry and medicine. In the production of AdBlue by the "blending" method, urea granules of the highest quality, the so-called "Automotive Grade Urea" (Automotive urea), are used.

So, the fundamental difference between the two AdBlue production methods is that with the “direct method” right at the Nitrogen Plant, immediately after the synthesis of the urea itself, it is not granulated, but immediately mixed with demineralized water. Often the producer of the urea solution by the "direct method" is referred to as the "Primary Producer" of AdBlue.

And "blending" (secondary method) involves the purchase by an AdBlue manufacturer of urea in granules at the same Nitrogen Plant, followed by mixing it with demineralized water in its production.

The "direct method" is considered more advanced, since the granulation process itself and the subsequent movement of raw materials to the manufacturer are excluded, which ensures the highest quality of AdBlue and to a greater extent eliminates possible undesirable impurities in the finished diesel urea solution.

In any case, all "primary" and "secondary" AdBlue manufacturers are the official holders of the license for the AdBlue trademark, strictly adhere to the standards and requirements in this area and produce a quality-assured product that complies with the ISO 22241-1 standard.

Along with licensed, that is, legal producers of AdBlue, there are other manufacturers of "urea for diesel" on the Russian market who do not have the right to call their product AdBlue. In order to give the buyer confidence in their "urea" and to make a connection with the quality of licensed AdBlue, these manufacturers often call their products by similar names, where the word "BLUE" appears such as such-Blue, any-Blue, best-Blue, etc. Sometimes they even call their urea for diesel "a complete analogue of AdBlue", which misleads the consumer and is a copyright infringement on the AdBlue trademark.

The quality of "imitator" products is not guaranteed by any quality control systems.

All car manufacturers recommend the use of "diesel urea" under the brand name AdBlue. This will guarantee the quality of the AdBlue fluid used in the SCR system and the durability of the vehicle's catalyst components.

Today in Russia there are 4 legal licensed producers of AdBlue.

EUROCHEM is the only manufacturer of AdBlue using the "direct method" in Russia.

Why is AdBlue the only quality guarantee for diesel urea?
What is, in a broad sense, Adblue or urea for a diesel engine, you probably know.
Recall that this is an aqueous solution of urea that is used in SCR (selective catalytic reduction) systems for cleaning exhaust gases from diesel engines.

Diesel urea quality requirements are set out in ISO 22241-1. That is, the product must comply with the chemical and physical parameters specified in this standard.

This is what most manufacturers of diesel urea usually say in the descriptions of their products and are very fond of putting appropriate intriguing inscriptions on the canister such as "Conforms to ISO 22241-1" or "AUS 32". But in fact it is only a declaration of intent. But how is this statement confirmed? Yes, maybe their product meets this standard, but who checked it? What organization can confirm this? You just have to trust this statement of the manufacturer.

A slightly different situation is with the product, on which the name of the AdBlue trademark appears. What is the difference?
Only those manufacturers who have passed the audit of the entire chain of production and sale of this liquid have the right to use the AdBlue trademark. That is, they were checked: where and what raw materials they purchased, what equipment and structural materials are used in the production and storage of AdBlue, the compliance of the container, and most importantly, they checked the chain of sale of the liquid itself.

The results of the analyzes of each batch of product, batch certificates and other documents must be kept for up to 5 years. If there are problems with the quality of AdBlue, it should be possible to trace the product batch back to the manufacturer. After passing the audit with a positive result, the manufacturer receives a license to use the AdBlue trademark. But that's not all. The licensed authority (VDA) can also check the quality of the product later in the retail chain. And the most interesting and reliable quality assurance mechanism is the AdBlue license holders themselves. They look after each other, so to speak, and none of them is interested in losing the license obtained at such a price.

The AdBlue trademark is licensed by the industry body VDA. This is the German Automotive Industry Association. By the way, it standardizes many components and processes for the production of cars.

All European and most global car manufacturers recommend using only AUS32 under the brand name AdBlue.

What are the potential risks when buying non-licensed “imitator” products under various names such as your Blue, my Blue, etc. read the article "Why is AdBlue not "urea"?".

What is AUS 32?
The technical term AUS 32 (Aqueous Urea Solution 32%) translates as "32% aqueous urea solution". The term is applied to the fluid used in SCR (Selective Catalytic Reduction) systems for cleaning the exhaust gases of diesel engines.

By itself, the term AUS 32 is generic and does not guarantee any quality of a particular product. Well, for example, as the abbreviation AI-95, it means motor gasoline with an octane rating of 95, and it still does not guarantee the purity of this fuel.

The quality of "diesel urea solution" AUS 32 rules for its circulation, transportation and storage is regulated by the provisions of the ISO 22241 standard.

This standard has 5 parts.
Part 1 - Approves quality requirements.
Part 2 - Defines fluid testing methods.
Part 3 - Defines the rules for circulation, transportation and storage.
Part 4 - Defines a refueling device for trucks.
Part 5 - Defines a refueling device for passenger cars.
The provisions of the ISO 22241 part 1 standard are only requirements for the quality characteristics of AUS 32, but ISO does not bear responsibility for the actual quality of a product produced by anyone, and the quality will not be checked in a retail network. This is, as it were, the minimum standard for the quality of the "urea for diesels" solution, which is recommended to be guided by the manufacturer AUS 32.

Aqueous urea solution AUS 32 can in principle be produced by any company. She can even state on the packaging that her AUS 32 product complies with the ISO 22241-1 standard. But this compliance is declarative, it may or may not, in practice, no one checks this compliance in the retail network.

So don't be fooled by that cryptic term AUS 32 on a package of diesel urea. It can only be dust in the eyes.

The only quality guarantee for diesel catalytic converter fluid is the AdBlue trademark.

Can I make my own AdBlue urea?
This is the second most popular question asked of us.

Popular formulation: Do-it-yourself or homemade AdBlue urea solution.

Answer: Purely theoretically, it is possible to make a urea solution yourself. Because everything is done by someone. But in practice, everything is somewhat more complicated. We responsibly declare that it is practically impossible to produce a solution of "urea for diesel" of the required quality at home. You probably heard somewhere that making urea for a diesel engine is simple: take water, add urea and you're done. This is a delusion and such a homemade "potion" will kill the catalyst of your car. Here are a few reasons why this might happen.

The first and main reason. Anti-caking agent and Biuret.
The raw material for the manufacture of "urea for diesel" is granular urea, which is a common mineral fertilizer. So, these agricultural urea granules are coated with a special composition, an anti-caking agent, which prevents the granules from sticking together during storage. Substances included in the composition of the anti-caking agent clog the pores of the catalyst of the car in which AdBlue is used. It's almost impossible to filter them out. Also in the urea for fertilizers, the level of Biuret is too high (1.6%). Biuret is another substance whose quantity in urea is an important parameter in assessing its quality. In the production of AdBlue, a special high-purity urea, not treated with an anti-caking agent, with a low biuret index (0.6%) is used. It is called "Automobile urea". You probably won't be able to buy it. "Automotive urea" in Russia is produced only by a few large "Nitrogen Plants", they supply it in large quantities, it is not sold in industrial containers and to individuals.

The second reason. Demineralized water.
The "diesel urea" solution must be made with demineralized water, as the metal salts present in ordinary untreated water clog the pores of the catalyst and cause it to fail over time. Of course, you can buy demineralized water somewhere, but as a result, the total cost of your "cocktail" will most likely no longer be so cheap. And the whole point of your idea will be lost. Manufacturers of urea for diesel AdBlue produce demineralized water themselves and its cost for them is an order of magnitude cheaper than the water you bought in a canister.

Do not listen to the "tales" of experienced "experts" about the fact that you can make high-quality urea for a diesel yourself. The use of homemade urea for diesel or urea of dubious origin is fraught with consequences.

What should be remembered when transporting and storing AdBlue?
To avoid loss of AdBlue quality, the following points should be kept in mind:
Long-term storage at temperatures above +25°C is not recommended;
The liquid freezes at temperatures below -11°C;
Keep away from direct sunlight;
Long-term storage at temperatures above 30°C will shorten the shelf life of AdBlue;
To avoid contamination, storage containers must be original and tightly closed.
All materials used in the manufacture of tanks and containers, including hoses, control fittings and fixtures for storage, transport and handling, must be compatible with the AdBlue urea solution (AUS32). Materials for samplers, sample storage tanks and canister must be compatible with the AdBlue urea solution. Read more in the section "Rules of storage and circulation of AdBlue".

What is the consumption of AdBlue urea in a passenger car?
AdBlue consumption in a passenger car depends on driving style, type of trip, vehicle load and environmental conditions and is approximately 1-3 liters per 1000 km. run. The size of the Adblue tank on different makes and models of cars can be from 5 to 30 liters. That is, on a full tank of AdBlue urea, you can drive about 5-20 thousand km.

How long can AdBlue be stored?
The shelf life of the AdBlue urea solution is then 6 to 36 months depending on the constant storage temperature.

At a constant storage temperature of +10°, the shelf life of Adblue is 36 months.
At a constant storage temperature up to + 25 °, the shelf life of Adblue is 18 months.
At a constant storage temperature up to + 30 °, the shelf life of Adblue is 12 months.
At a constant storage temperature of +35°, the shelf life of Adblue is 6 months.
After the expiration date of AdBlue, samples must be taken and tested to decide on the future use of the product.

Why is it not worth filling AdBlue into a passenger car from truck dispensers?
Recently, filling stations for AdBlue urea began to appear at gas stations. This is undoubtedly a positive sign. Since refueling AdBlue in a truck and, in particular, in a passenger car from a dispenser directly to the tank is the most convenient way to resolve the issue of refueling.

But, unfortunately, today almost all AdBlue dispensers at gas stations are designed for refueling trucks. And we do not recommend you to refuel AdBlue in your passenger car from such a “truck” dispenser. This is due to some design features of the SCR system on passenger cars. The location of the AdBlue tank in a passenger car can be quite unusual, the thin AdBlue filling tube and other design features of the system require certain conditions to be met when topping up with AdBlue. The main features of refueling AdBlue in a passenger car are the rate of fluid supply to the tank and the design of the filling nozzle.

AdBlue filling nozzle for passenger cars
For these reasons, the ISO 22241-5 standard has been specifically created for AdBlue filling nozzles in passenger cars. The passenger car AdBlue gun is specially designed to fit snugly on the AdBlue tank filler neck, the tank evacuation system and the fluid flow rate control valve.

The liquid supply rate in the AdBlue dispenser for passenger cars is 3-5 liters/min, and in truck dispensers 35-40 liters/min. Pay attention - AdBlue filling in a car should be 10 times slower than in a truck! When filling AdBlue from a truck dispenser into a passenger car, the gun may cut off the fluid supply and prevent the AdBlue from being filled into the tank properly. And you can also easily pour AdBlue from the tank onto the car body.

Spilling Adblue from the tank onto the car body is not a very pleasant case, as “diesel urea” can cause corrosion if it is not washed off in time. If a spill occurs, you must immediately clean the car body from the spilled Adblue liquid.

Try to avoid refilling AdBlue into a passenger car from "truck dispensers".

We hope that the infrastructure of AdBlue dispensers for passenger cars will start to develop in the near future.

Can AdBlue freeze?
Yes, AdBlue urea freezes at -11.5°C

Once the AdBlue has melted, it can be used without any problems. Due to the composition of AdBlue urea, the first drop of thawed liquid has the same quality as indicated in the specification.

What is DEF and ARLA?
In the user manuals and technical documents of some car manufacturers, in matters related to SCR fluid, along with the AdBlue trademark, you may come across terms such as DEF, ARLA or AUS32.

The term DEF is used primarily in the US. And literally it translates as “liquid for diesel exhaust” (Diesel Exhaust Fluid). In fact, in our Russian version, this is the same as “urea for diesel”. Does DEF mean the same as AdBlue? No, just like "diesel urea" is not the same as AdBlue. The quality of AdBlue, in contrast to "just urea for diesel", is additionally controlled by the European industry organization VDA*. In America, to control the quality of DEF “in the field”, they use their own quality system - API Diesel Exhaust Fluid Certification.

API or "American Petroleum Institute" is an organization that regulates and standardizes issues related to the oil and gas industry. You've probably come across this abbreviation on canisters of motor oils. Well, the API also certifies DEF manufacturers in the US. The “API DEF Certification” certification system for DEF is very similar to the AdBlue certification from the European VDA*.

The term ARLA (Automotive Liquid Reducing Agent) is used in Brazil and stands for "diesel engine SCR fluid" similar to AUS32 and DEF.

Can AdBlue be used after freezing?
Yes. Once the AdBlue has melted, it can be used without any problems. Due to the composition of AdBlue urea, the first drop of thawed liquid has the same quality as indicated in the specification.

Can AdBlue ignite?
No. Being an aqueous solution of urea (67.5% water), AdBlue is not capable of igniting.

Does AdBlue cause corrosion?
Yes, AdBlue is corrosive to metals. Therefore, you should avoid getting liquid on the metal parts of the car body. If this cannot be avoided, the remaining AdBlue must be thoroughly washed off with water.

What measures should be taken if AdBlue gets on the car body?
AdBlue® must be washed off with water and the residues must be scraped off the surface of the body. If AdBlue® dries up and crystallizes on the surface of the body, it can cause corrosion.

What quality standards must AdBlue meet?
AdBlue quality performance requirements are set out in ISO 22241-1.

When it comes to AdBlue quality in "real life", from the warehouse at the manufacturer's factory through the distributor, right up to the shelf in the store or the dispenser at the gas station, are governed by the terms of the license agreement between VDA (Owner of the copyright of the AdBlue trademark) and the AdBlue manufacturer.
