The Thunder Creek Equipment 1,200-gal bulk diesel exhaust fluid (DEF) tank is an ISO-compliant (ISO 22241) closed system that is available with either a polyethylene DEF tank or an industry exclusive stainless steel tan. It can be outfitted with either single- or dual-sided dispensing stations, and the tank is designed to accommodate the value of bulk fluid deliveries of 1,000 gallons while still keeping a serviceable amount of DEF in the tank. The Thunder Creek dispensing system pumps DEF at 10 gallons per minute and features a digital DEF meter, 20' auto-retracting hose reel and weather-sealed nozzle enclosure. An optional, thermostatically controlled cold weather package includes a six-sided/2" R19 insulation wrap, a tank temperature monitor, a Powerblanket heating system, heated dispensing cabinet and a heated piping bridge enclosure.
