Webasto Offers Engine-Off Cooling System for Off-Highway Equipment

PTP PolarCab 300To complement its Polar Cab TS, an engine-off cabin cooling system that features exclusive thermal storage technology, Webasto launched the all-new Polar Cab ES at the 2016 CONDEX Show.

The new Webasto Polar Cab ES maintains cool cabin temperatures during wait/load time in hot, humid and full sun conditions. Operators can now turn off their engines and keep comfortable, leading to fuel savings, idle reduction and increased productivity.

“Developing two off-highway operator comfort solutions, one being battery driven and the other featuring a one-of-a-kind thermal storage technology, is what our engineering, research and development teams have worked hard to execute,” said Webasto Thermo & Comfort North America President and CEO, Dr. Rolf Haag. “We identified this as a need in the industry and see it as an opportunity for operators to increase productivity while decreasing fuel costs and engine hours.”

Webasto’s Polar Cab ES battery-driven electric cooling system offers a cooling capacity up to 7,000 BTU/h while maintaining low power consumption and includes a compact 24V variable-speed electric compressor, with no additional batteries required for operation.

The Polar Cab ES can be installed with one of two different aftermarket kit configurations. Operators can decide between a universal overhead compressor/condenser unit with evaporator (Oakland) or a universal vertical floor mounted compressor/condenser unit with evaporator (Osaka). Kits include refrigerant lines and fittings, mounting hardware, control unit and wiring harness.

The Polar Cab TS engine-off cabin cooling system features an exclusive thermal storage technology. Inside the storage core is 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. Cold energy is transferred to the cab for on-demand enging-off cooling.

The Polar Cab TS has a cooling capacity of up to 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 three 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.
