Webasto introduces engine-off cabin cooling for off-highway equipment

The new Webasto Polar Cab TS engine-off cabin cooling system provides on-demand cooling during down time which results in fuel savings, reduced idle time, increased productivity and operator safety and comfort, the company announced.

“Designing products with operator safety and comfort in mind is a big part of our business plan at Webasto,” said Webasto Thermo & Comfort North America President and CEO Rolf Haag. “Webasto products provide operators an opportunity to reduce machine hours, scale down fuel costs, lease payments, and lower annual maintenance costs.” 

Webasto said its Polar Cab TS engine-off cabin cooling system features a 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,” the company noted. “This cold energy is transferred to the cab for on demand cooling via a compact air handler, which results in operator comfort and fuel savings”.

The company added that the system has a cooling capacity of 1.3kW (4,450 BTU/h) and does not require any additional batteries. The system can be fully recharged within three hours, according to the company.

In addition, Webasto said it 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. The system can be installed at the dealership on new equipment as well as on existing equipment.
