Engine-off A/C that puts driver comfort first

Webasto’s engine-off air-conditioning systems turn the truck cab ito a comfortable, cool retreat even in extreme heat, giving drivers the restful breaks and quality sleep they need. Operating independently from the engine, this parking cooler delivers steady, dry airflow without idling – reducing fuel use, cutting emissions, and lowering operating costs. By avoiding unnecessary run time, fleets also benefit from reduced engine wear and longer maintenance intervals, ensuring trucks stay ready for the road while drivers stay refreshed.
