DES began in 2007 as a division of North State Truck Equipment, Inc. to service the heavy-duty diesel market. Over the last decade, the focus has shifted to HD diesel emissions.
We’ve continued to grow into other areas of diesel aftertreatment including retrofits, emissions parts, servicing, diagnostics, and DPF Cleaning. DES operates several successful DPF cleaning facilities in California, Oregon, and Vancouver, BC.
We have recently increased manufacturing capacity for the full line of DPF cleaning machines at our Redding CA location.
We are proud to be distributed by the Redline Emissions Products brand. REP offers a full line of aftertreatment parts, including OEM replacements for DPFs, DOCs, gaskets, clamps, sensors, weld bungs, and more.
