The Webasto Polar Cab TS engine-off cabin cooling system provides on-demand cooling during down time that will result in fuel savings, reduced idle time, increased productivity, and operator safety and comfort.

The Polar Cab features a patented storage core with a series of aluminum micro-channels, which route liquid refrigerant around a graphite honeycomb substrate that is impregnated with water. This substrate is capable of storing cold energy at an extremely high efficiency. This cold energy is transferred to the cab for on demand cooling via a compact air handler.

The cooling system has a cooling capacity of 1.3 kilowatts (4,450 BTU/h), does not require any additional batteries, and consumes very little power. The system can be fully recharged within three hours. Webasto offers Polar Cab TS as an aftermarket kit which includes the thermo storage core, electrical compressor (24-volt), condenser with fan, air handler, wire harness, and miscellaneous hardware needed for installation. The system can be installed at the dealership on new equipment as well as on existing equipment.
