About DES

Diesel Emissions Service (DES) began its operations in 2006 as the emissions division of parent company North State Truck Equipment, Inc., which has been serving the heavy duty truck market since 1978. DES was established to help California businesses meet and exceed the strict CARB and EPA emissions regulations placed on diesel trucks. Since 2006, DES has sold and/or installed over 15,000 emission control devices, and is now an industry leader in diesel emissions on the west coast, with a rapidly expanding Service Partner Network throughout the U.S. and Canada. 
 
DES manufactures DPF (diesel particulate filter) equipment and accessories, we sell and distribute other popular industry DPFs and accessories, and we clean, service and retrofit DPF filters. In 2014, DES began manufacturing DPF cleaning equipment under the Filtertherm brand as an industry response to outdated cleaning technology. In 2016, DES launched its Redline Emissions Products brand to cover the DPF equipment needs for the light, medium and heavy duty diesel markets. We offer DPFs, gaskets, clamps, weld bungs, CACs (charge air coolers), sensors, brackets, guards and custom mounting kits. We have our own AMADA stamping press with complete fabrication facility, and we have a certified electrical control panel UL shop.
 
DES has one of the largest replacement OEM filter inventories in North America and have begun distributing in both Canada and Australia. We have six locations on the west coast.
