New technology provides the lowest cost method of low emission (LETRU) compliance for your 2003 and older TRUs. It’s easy to install, requires minimal maintenance and has no impact on fuel consumption.

Installation kits are available for Thermo King SB, Super II, Whisper, Spectrum, Sentry, CD, JD, MD, KD, RD, TD, TS200, TS300, TS500, TS600, XDS, and other model TRUs. (1985-2003 for trailer TRUs, 1987-2002 for Bobtail TRUs)

The Proventia TRU filter is a Flow Through Filter (FTF), which collects exhaust soot in a metal filter media and holds it until it can be regenerated. The filter regenerates, or cleans itself, under normal TRU operation, without operator intervention.
