Driver's cab vapor air conditioning unit
Vapor cycle systems
With extensive expertise, Liebherr provides vapor cycle air-conditioning systems for various applications, serving both driver’s cabs and passenger saloons. Available as compact or split units, roof-mounted or floor-mounted, these systems ensure optimal comfort with seamless vehicle integration, high output density, and reduced weight and noise emissions. The vapor cycle operates as a closed-loop system, with cooled air intake functioning independently of the cooling process. Pressure protection devices for fresh and exhaust air intake ensure consistent passenger and crew comfort, even at high speeds.
