Preheating from Eberspaecher

Eberspaecher’s AIRTRONIC Air Heaters
Eberspaecher’s air heaters are independent of both the engine and the vehicle’s own heat balance. They draw in either cool room air or outside air, heat this up and then deliver it to the interior of the vehicle. Air heaters are an excellent option for commercial vehicles of every type.
Eberspaecher’s HYDRONIC Coolant Heaters

Eberspaecher’s coolant heaters work independently of the engine and thus offer a double plus: preheating the vehicle’s passenger compartment as well as the engine. The heaters are integrated into the cooling system of the engine. The thermal energy gained is then distributed through the vehicle’s own heat exchanger as forced hot air and this heats the interior of the vehicle via existing air vents. The engine is warmed up with the residual heat in the cooling water.

Easy to Operate

Eberspaecher heaters operate as miniature furnaces that are independent of the engine, utilizing the unit’s own diesel and batteries to produce heat.


Hydronic units heat the coolant, then circulate it to warm the engine and heat exchangers to near operating temp and can be sized to provide auxiliary heat for other critical fluids. Eberspaecher air heaters heat air directly and circulate air to applicable compartments.

AIRTRONIC heaters can provide ample heat to the cab, mobile work stations, crew shelters, etc., all without idling the engine.


Using timer controls, heaters can be switched on to begin engine preheating at preset intervals, allowing operators to go directly to work upon arrival.
