Indel Webasto Isotherm cooling units with Automatic Start Up (ASU) technology

It comes with box evaporator.
This version achieves unbeatable power savings up to 25-30%. The electronic system detects a surplus of power when the engine is running: in this case it runs the SECOP compressor at the highest speed to freeze the holding plate.
When the engine is off, the electronic system runs the compressor only if the cold in the holding plate is totally exhausted and for short periods depending on the temperature set.
