Why Urea Quality Matters in AdBlue® Production
At Atmosfer Makina, we recognize that in the world of modern diesel engines, AdBlue® (Diesel Exhaust Fluid or DEF/AUS32) is far more than just another fluid — it is an essential element for meeting stringent environmental regulations and ensuring peak vehicle performance. At the core of every high-quality AdBlue® solution is the purity of urea. Upholding the highest standards of urea quality is not just our business; it is our pledge to sustainability and to the reliable operation of your SCR (Selective Catalytic Reduction) systems.
As global emission standards continue to tighten, SCR technology has become the industry standard for diesel vehicles. AdBlue®, a precisely formulated 32.5% solution of ultra-pure urea in demineralized water, is injected into the exhaust stream, converting harmful nitrogen oxides (NOx) into harmless nitrogen and water vapor. This process is extremely sensitive, and even minor impurities in urea can compromise its effectiveness, causing system damage, increased emissions, and costly downtime.
For this reason, Atmosfer Makina proudly supplies Prilled Urea Without UF, specifically produced for AdBlue® manufacturing. This grade of urea is manufactured under strict ISO 22241 standards, ensuring that every batch delivers maximum performance, protects your SCR system, and keeps you in compliance with environmental regulations.
The Impact of Urea Purity on SCR System Performance
The performance and longevity of your SCR system are directly tied to the purity of the AdBlue® it uses, and therefore to the quality of the urea it is made from. Even minimal contamination can lead to serious problems:
- Catalyst Poisoning: Trace metals (like calcium, iron, copper, zinc, chromium, nickel) and other impurities can poison the sensitive SCR catalyst, reducing its ability to convert NOx effectively.
- Clogging and Damage: Dust, insoluble particles, or excessive biuret — a common urea byproduct — can crystallize inside the dosing system, blocking injectors and causing uneven spray patterns or total failure.
- Lower Efficiency: Impure urea reduces the chemical reaction efficiency, leading to higher emissions and potential regulatory non-compliance.
- Higher Maintenance Costs: Poor-quality urea leads to more frequent repairs, replacement parts, and downtime, negatively affecting your operational bottom line.
Atmosfer Makina’s Prilled Urea Without UF meets the most stringent purity criteria: minimum nitrogen content of 46.2%, maximum biuret of 0.9%, maximum aldehydes of 15 mg/kg, and maximum moisture of 0.5%. We also carefully limit heavy metals, phosphate, and insoluble matter to prevent system degradation. Our product’s highly uniform particle size (98% between 1–2.8 mm) ensures fast dissolution and optimal performance in AdBlue® production — unlike general-purpose agricultural urea, which is unsuitable due to its impurities and slow solubility.
How to Ensure Compliance with ARLA 32 Standards
Complying with international standards such as ARLA 32 (equivalent to ISO 22241) is not optional — it is essential for maintaining the integrity of your SCR systems and for meeting global emissions regulations. Non-compliance can result in:
- Legal Penalties: Regulatory fines, vehicle bans, or recalls.
- Voided Warranties: Manufacturers may refuse warranty claims if poor-quality AdBlue® was used.
- Reputational Harm: AdBlue® producers who supply substandard products risk losing customer trust and market credibility.
Atmosfer Makina supports your compliance efforts by supplying Prilled Urea Without UF manufactured specifically to meet ISO 22241 specifications. We include complete technical documentation with each batch, providing full transparency and traceability. When you choose Atmosfer Makina, you ensure that your AdBlue® production begins with certified, reliable raw materials — every time.
Essential Equipment for High-Quality Urea Processing
Producing world-class AdBlue® requires more than just high-purity urea — it demands precision and control throughout the production process. At Atmosfer Makina, we help our customers achieve operational excellence by supplying not only the right raw material but also the right guidance and expertise to maintain quality and compliance.
We emphasize the use of reverse osmosis (RO) water purification systems, as high-purity demineralized water is just as critical as high-purity urea. Standard or tap water contains minerals and impurities that can harm SCR systems. That is why we recommend pairing our Prilled Urea Without UF with RO-treated water for guaranteed ISO-compliant AdBlue®.

Frequently Asked Questions About Urea Quality and AdBlue® Production
Why is urea purity so critical for AdBlue®?
Atmosfer Makina: Because impurities can damage SCR systems, reduce efficiency, and lead to costly repairs. Only high-purity urea ensures proper NOx reduction.
What makes “Prilled Urea Without UF” different from agricultural urea?
Atmosfer Makina: Our product is ultra-pure and specifically produced for DEF, while agricultural urea contains unacceptable impurities.
How can I be sure your urea meets ISO 22241?
Atmosfer Makina: Each batch comes with full technical documentation and is manufactured to strict ISO 22241 standards.
Can I use regular water to mix AdBlue®?
Atmosfer Makina: No. You must use demineralized water, ideally from RO systems, to avoid introducing contaminants.
What particle size is recommended for urea in AdBlue®?
Atmosfer Makina: Our urea is 98% within 1–2.8mm for optimal dissolution and performance.
What happens if poor-quality urea is used?
Atmosfer Makina: It can clog injectors, poison catalysts, void warranties, and cause higher emissions.
Does your urea dissolve quickly in water?
Atmosfer Makina: Yes. Its uniform prilled structure ensures fast, even dissolution — superior to granular urea.
What support do you offer to AdBlue® producers?
Atmosfer Makina: We provide consultation, technical support, and ongoing guidance for maintaining compliance and performance.
How should Prilled Urea Without UF be stored?
Atmosfer Makina: Store in a cool, dry, contamination-free environment to maintain purity.
