The EFFINOX green caveat refers to the strict IMO and engine manufacturer requirements for reduction agents used in advanced SCR systems. Standard urea solutions may contain trace impurities (such as biuret, aldehydes, or metal ions) that can degrade sensitive catalyst coatings over time. EFFINOX-certified reagents meet tighter purity tolerances, ensuring full compatibility with SCR catalysts from manufacturers like MAN, Wärtsilä, and WinGD. Choosing EFFINOX protects your catalyst investment and maintains Tier III compliance.

We provide every customer with a digital refractometer calibrated for either AUS40 (target 40%) or DEF Solutions (target 32.5%). Before you accept any delivery, you take a small sample from the transfer line, place 2-3 drops on the refractometer prism, and read the result within 3 seconds. The display will show a clear PASS or FAIL. You only accept the delivery if the reading is within specification. Every shipment also comes with a Certificate of Analysis (COA) documenting batch test results.
