Webasto’s Polar Cab TS engine-off cabin cooling system features the company’s proprietary storage core and a series of aluminum microchannels engineered to route liquid refrigerant around a graphite honeycomb substrate that is impregnated with water. The substrate is designed to store cold energy that can be transferred to the cab for on-demand cooling via a compact air handler at a capacity of 1.3kW (4,450 Btu/h). The system doesn’t require additional batteries and can be recharged within three hours.
