LOUISVILLE, Ky. — Webasto has now combined its popular Air Top 2000 forced-air heater and BlueCool Truck air conditioner as a complete system

Marketed under a “complete cabin climate comfort control” philosophy, the “C5 Truck” allows users to cool and heat their truck sleeper bunks without depending on power from an idling diesel engine.

The cooling component of C5 Truck, BlueCool Truck, is charged (frozen) during the day while the truck is running. At night, the patent-pending BlueCool Truck’s innovative cold storage unit provides a source of cold, dehumidified air to the bunk area with no further use of a powered air-conditioning device. It utilizes only small amounts of electricity from the existing vehicle batteries to circulate super-chilled coolant between Webasto’s cold storage unit and heat exchanger installed in the truck sleeper cabin. Pushed by four small, exceptionally quiet air distribution fans, the cold air will keep the bunk area cool for eight to 10 hours in most ambient conditions.

The other component of the C5 Truck, Air Top 2000, is a forced-air heater that uses diesel fuel from a vehicle’s tank to warm the interior. It uses 1/20th of a gallon of fuel per hour, much less than an idling engine’s one gallon per hour while emitting far fewer emissions. With an output of 7,000 Btu/h, this compact heater provides instant, quiet and safe overnight heating. Air Top 2000 can be operated via an optional timer or manually controlled. Both Air Top 2000 and BlueCool Truck are EPA-recognized anti-idling devices.

C5 Truck can be combined with Webasto’s TSL 17 engine preheater, which reduces engine wear while ensuring starting capability. This device, mounted in-line with a vehicle’s engine cooling system, has a heat output of 17,200 Btu/h.
