Diesel Exhaust Fluid Manufacturer - producing DEFendal™ Diesel Exhaust Fluid
DEFendal™ Diesel Exhaust Fluid is a DEF product that is comprised of 2 major components; urea and Deionized water (DI). Urea is an organic compound with the chemical formula (NH2)2CO. Urea has common uses in fertilizer, agriculture, and the pharmaceutical industry. Urea is used at a 32.5 % mixture with 67.5% DI water in DEFendal™ Diesel Exhaust Fluid in Selective Catalytic Reduction Systems (SCR). The fluid is in used to reduce the NOx pollutants, in exhaust gases from combustion from diesel, dual fuel, and lean-burn natural gas engines. In afore mentioned SCR systems; a water based urea solution is injected into the exhaust system. The ammonia produced by the hydrolysis of urea reacts with the NOx emissions and is converted into nitrogen and water within the catalytic converter.

ABOUT Diesel Exhaust Fluid Manufactuer

What is Diesel Exhaust Fluid (DEF Product)?
You are probably reading this page because you recently bought a new 2010 truck or are thinking about buying one and want to learn about SCR, and have more than a few questions about Diesel Exhaust Fluid (DEF).  Diesel Exhaust Fluid (DEF) is a harmless and safe-to-handle solution of urea in water - about a third urea to two thirds water - that is required by many new diesel trucks and buses equipped with an exhaust emissions control technology known as selective catalytic reduction (SCR). Some agricultural, construction and forestry equipment will soon need Diesel Exhaust Fluid (DEF) too.

Why do I need it?

The reason that you need to use Diesel Exhaust Fluid (DEF) and SCR lies with the EPA and legislation it enforces known as the Clean Air Act. This document requires the EPA to regulate emissions of NOx and PM.  The trucking industry has been split in two by this latest piece of rulemaking and manufacturers are pursuing to technology pathways. Daimler, PACCAR, Volvo, Mack, Isuzu, Hino and others are using SCR, while Navistar has decided to go it alone and use an extension of its 2007 MaxxForce EGR technology.  SCR technology offers drivers many benefits, most importantly great fuel efficiency. On top of this, drivers purchasing an SCR truck will enjoy greater reliability and a longer oil change interval, all of which adds up to impressive savings over the life of the vehicle.
