About Us

How We Handle DEF

DEF, or Diesel Exhaust Fluid, is one third pure ammonia and must be handled and stored safely. We keep our DEF sealed at the recommended 12 to 86 degrees Fahrenheit. Our company uses only sterile, containment free containers for storage and transfer. No additives are required, as DEF must keep a precise mixture of 32.5% high-purity synthetic urea and 67.5% deionized water. In addition to using API (American Petroleum Institute) approved DEF, we field test our DEF using precise refractometers to determine when it is time to replace the fluid based on the concentration of water based solubles. 


 We handle your Diesel Exhaust Fluid needs directly to your vehicles, so there is no need for the safety precautions normally found in this product. Our well trained service technicians will efficiently ensure all of your fleet DEF replenishment.
