Separation By Design has been on the cutting-edge of developing Diesel Exhaust Fluid (DEF) storage and dispensing solutions through its KleerBlue brand name. We offer a full line of innovative solutions for retail truck stops, commercial fleets, private fleets, construction and agricultural equipment. Even before the emergence of DEF in the US market, we made it our business to understand DEF’s stringent purity and temperature requirements as well as the logistical concerns of the industry. Separation By Design’s quick response to providing solutions to this emerging industry has made us an early leader in DEF handling solutions. The result is a full range of solutions including basic drum/tote dispensing solutions, bulk storage systems, portable/fixed bulk delivery systems, blending/dilution systems, fueling island-friendly mini-bulk storage/dispensing systems and custom designs.
