Our (AST) DEF storage tanks systems ranging from 550 gallons to 5000 gallons have been specifically designed and constructed to meet the demands of a complete closed system from bulk filling to dispensing nozzle. This closed system incorporates a stainless steel tank with DEF approved pump and equipment assuring delivery of quality DEF to your vehicles. In addition, we integrate an external thermal barrier with a PVC protective jacket, and the dispensing equipment is housed in an enclosed module offering protection and ease of maintenance.

We offer basic to advanced touch screen controls along with freeze protection for tank and module allowing you various options for DEF bulk storage that meets your needs.
