The TM31 / DKS32 Compatibility Story
The Valeo TM31 is one of the most cross-referenced bus compressors in the world – because its platform is shared with the Zexel DKS32. That means a single rebuilt TM31 core answers the same fitment demand as DKS32-spec units across multiple brands and chassis, dramatically simplifying your stocking decision.
At 313 cm³/rev across 10 cylinders, the TM31 sits between the TM21 and TM43 in the Valeo family – the thermal core for long-haul coaches, city buses and refrigerated truck fleets.
