Espar's AIRTRONIC Air Heaters

Espar's air heaters are independent of both the engine and of the vehicle's own heat balance.

They draw in cool room or outside air, heat this up and then deliver it to the interior of the vehicle.

Air heaters are an excellent solution for commercial vehicles of every type. They can be installed just as well in the cab as in the luggage compartment or under the floor.

Practical controls - such as a digital Espar timer - make your comfort perfect.

Applications:
BUS - Pre-Heaters for Buses
Suitable Units: AIRTRONIC 4 (significant supplemental heat for 26 passenger buses or smaller), AIRTRONIC 5
A pre-heated bus, a clear view for the driver and passengers right from the start, warmth also at the rest stop and in traffic jams are strong arguments for the powerful heaters from Espar. Espar air heaters do not provide engine heat but are quicker to recuperate heat lost during service stops.

TRUCK - Cab Comfort and Engine Pre-Heating
Suitable Units: AIRTRONIC 2, AIRTRONIC 4
Espar Heater Systems manufactures diesel-fired heating systems to provide cab and sleeper heat in trucks, eliminating the need to idle the engine for heat. Espar also supplies independent coolant systems for quick engine pre-heating. These systems require no electrical plug-ins and are ideal for cold weather starting.

OFF-HIGHWAY EQUIPMENT - Pre-Heaters for Building Machines and Agricultural Vehicles
Suitable Units: AIRTRONIC 2, AIRTRONIC 4
Espar Off-Highway Equipment Heaters can provide engine preheat, cab comfort and windshield defrost. We offer two basic types for building machines and agricultural vehicles: air heaters and water heaters. Both systems satisfy the highest demands on sturdiness and cost
effectiveness.
