Automotive Grade Urea is special urea for make best quality diesel exhaust fluid, technical grade urea is not suitable for def it may damage to catalytic converter silencer. Automotive urea is also known as Diesel Exhaust Fluid (DEF), is the registered trademark for AUS32 (aqueous urea solution 32.5%).

Automotive urea is made by mixing urea with demineralized water resulting in a 32.5% aqueous urea solution. After mixing, the urea solution 32.5 % is cooled and transferred to the storage tanks. The ration of the concentrated urea and demineralized water must be controlled to ensure the desired concentration of the final product.

How Urea SCR Systems Work

Urea SCR cleans the exhaust after combustion. The urea solution is held in a separate storage tank and injected as a fine mist into the hot exhaust gases. The heat breaks the urea down into ammonia—the actual NOx-reducing agent.
