DEF (Diesel Exhaust Fluid):
Diesel Exhaust Fluid (DEF) is an emissions control liquid required by modern diesel engines. It is injected into the exhaust stream. DEF is never added to diesel fuel. It is a non-hazardous solution of 32.5% urea in 67.5% de-ionized water. DEF is clear and colorless, and looks exactly like water. It has a slight smell of ammonia, similar to some home cleaning agents. DEF is used in Selective Catalytic Reduction (SCR) technology to remove harmful NOx emissions from diesel engines.
Offen Petroleum can make bulk deliveries of up to 5000 gallons in one of our specialized bulk trailers dedicated and equipped to carry DEF. We can also deliver 275 or 330 gallon “totes” in one of our enclosed box trucks. Bulk deliveries are loaded and unloaded using specialized DEF equipment including, hoses, fittings, pumps, and meters equipped with ticket printers that are calibrated and certified.
