At Senergy, we know Diesel Exhaust Fluid (DEF) is more than just a regulatory requirement—it’s a key part of keeping today’s diesel engines running clean and efficient. DEF is a non-toxic, colorless liquid that plays a vital role in reducing nitrogen oxide (NOx) emissions in engines that meet strict emissions standards. It’s not a fuel additive—instead, it’s stored in a separate tank and injected into the exhaust system, where it helps convert harmful NOx into harmless nitrogen and water vapor.
As environmental standards become more demanding across industries—from long-haul trucking to agriculture—DEF has become essential for staying compliant. But beyond emissions, DEF also supports better engine performance and longevity. Using DEF isn’t just the right thing for the environment—it’s the smart move for your equipment.
