AT Series Under-Mount Independent Refrigeration Unit TU1200ES

The TU-1200ES is an under-mount diesel-powered independent refrigeration unit by AT-THERMO, purpose-built for mid-to-large refrigerated trucks. Its defining advantage lies in mounting the entire power system beneath the vehicle — freeing up the full interior of the cargo body and maximizing every usable inch of loading space.
Under-Mount Design — Full Cargo Space, No Compromise
Conventional roof-mounted refrigeration units protrude into the front section of the cargo body, sacrificing valuable loading space. The TU-1200ES installs completely beneath the truck, leaving the interior entirely unobstructed. This significantly improves loading efficiency, making it the ideal choice for mid-to-large refrigerated logistics operations where space utilization is critical.
Keep the Cold Running — Even When the Engine Is Off
The TU-1200ES comes standard with an electric standby function. When docked at a loading bay or during cargo handling, simply connect to an external power source and the system automatically switches to electric drive — maintaining cargo temperature without interruption, eliminating diesel consumption, and supporting the low-emission management standards of modern logistics facilities.
German Compressor × Japanese Engine — Reliability You Can Trust
At its core, the TU-1200ES pairs a German BOCK compressor with a Japanese Kubota engine — both industry-proven components known for long-term durability. Combined with an automatic hot gas defrost system, routine maintenance requirements are minimal, giving operators full confidence across long-haul routes.
