Since 2010, the EPA has required every diesel truck to have a diesel exhaust fluid (DEF) tank onboard. The DEF system sprays the fluid into the exhaust to help eliminate the NOx emissions in diesel engines. DEF is a combination of urea and deionized water, and it is critical that the solution stay pure. Impurities will cause the DEF system to stop, which will shut down the operation of the truck.
We work with DEF manufacturers and distributors to provide reliable storage solutions that ensure their DEF stays 100% pure.
