The Espar’s Fuel Operated AIRTRONIC D2 / D4 / D5 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.
The AIRTRONIC heaters are designed for many types of applications. They are especially suited for cab and sleeper heat in trucks, workshop vehicles, freight
compartments and interior heat in general. These air heaters cycle quietly through four heat levels to mantain a desired temperature range, without idling your engine.
How an Espar Airtronic Air Heater Works
As soon as the heater receives its starting pulse, the following processes are triggered by the central control unit:
● Automatic safety check.
● The burner motor starts, the combustion space in pre-ventilated, the glow plug is warmed up, the metering pump conveys fuel.
● The glow plug ignites the fuel-air mixture, the flame is formed.
● The hot combustion gases flow through the heat exchanger.
● The hot air fan draws in room air or fresh air.
● The heat of the combustion gases is transferred by the heat exchanger to this hot air.
THEY ARE SIMPLE, EFFICIENT AND CONVENIENT!
Espar air heaters work as forced air furnaces utilizing the truck’s own diesel fuel and batteries to produce heat. Digitally controlled for consistent, comfortable warmth, AIRTRONIC heaters provide heat very quickly. The AIRTRONIC heaters can save over 1,000 gallons of fuel per year by reducing your idle time.
