Heating solutions for
agricultural machinery

Ready for use anywhere at any time thanks to efficient heaters for diesel and electric tractors, combine harvesters and others

Agricultural machinery must be ready for use at all times - regardless of outside temperatures and weather conditions. Those who operate the machines also need protection and a comfortable working environment whatever the weather. This is the only way to ensure their health and concentration on their work. To meet the high demands placed on man and machine, intelligent heating solutions of Webasto combine comfort and efficiency. They reliably warm cabs and engines both before and during use. Thanks to their engine-off technology, they also prevent unnecessary idling when stationary, for example. Our compact and efficient high-voltage heaters for electrically powered agricultural machinery fulfill their tasks accordingly.

Heating solutions for fuel-powered agricultural machinery

Webasto offers a wide range of applications and partsfor OEM and retrofit solutions for both air and water heaters.

For heating the vehicle cab and compartments you have thechoice of air heater models that range in output from 7,000 up to18,800 BTU/hr (2 and 5.5 kW). Air heaters pull in cold ambient airover a heat exchanger and blow it directly into the interior usingvariable air outlets.

Water heaters are integrated into the vehicle’s coolant loop to heatand circulate warm coolant through the engine to preheat andcondition the engine before startup. This allows for a reliablestarting procedure with less stress on components, hydraulicsystems, battery, and ultimately saving fuel by eliminating the need for idling.
