Description

Automotive-grade urea is the key raw material for producing AdBlue (DEF/AUS 32), a high-purity urea solution designed to reduce nitrogen oxide (NOx) emissions in diesel vehicle exhaust systems.

Our product features low biuret content and is free from aldehydes, ensuring the production of high-quality DEF that fully complies with ISO 22241 standards.

Risso produces SCR-grade urea, mainly from coal, with some sourced from natural gas. The process starts with industrial-grade urea, which undergoes purification, filtration, and dehydration to meet automotive-grade standards. Our strict quality control guarantees optimal performance in SCR systems for diesel engines.

Why Choose Our SCR Urea for DEF Production?

Our SCR-grade urea is made from pure natural gas, ensuring low biuret, low aldehydes, and low heavy metal content. This purity makes it ideal for DEF production, providing optimal performance in SCR systems. We use advanced production and testing equipment to ensure our urea meets the highest quality standards.
