Webasto, a global provider of equipment and vehicle heating and cooling solutions, has developed the Polar Cab TS engine-off cabin cooling system, which provides on-demand cooling during downtime and by doing so, offers fuel savings, reduced idle time, increased productivity and operator safety and comfort.

EQ Polar Cab TeaserThe cabin cooling system 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 system has a cooling capacity of 1.3 kW (4,450 BTU/h). The Polar Cab TS does not require any additional batteries and consumes very little power. The system can be fully recharged within 3 hours. Webasto offers Polar Cab TS as an aftermarket kit, which includes the thermo storage core, electrical compressor (24V), condenser with fan, air handler, wire harness and miscellaneous hardware needed for installation.
