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

For heating the cab, you have the choice between an air heater and a water heater. Our air-top models heat the air directly with a heat output of between 2 and 5.5 kW and blow it into the interior. The air outlet is variable. Webasto offers a wide range of applications and parts for individual original equipment and retrofit solutions for both air and water heaters. They can be integrated into 12 and 24 V environments and also heat with alternative fuels such as HVO and GtL. There are versions with an Arctic Start function for particularly cold environments with temperatures as low as -40 degrees Celsius and automatic altitude adjustment up to 5,500 m.

There are versions with an Arctic Start function for particularly cold environments with temperatures as low as -40 degrees Celsius and automatic altitude adjustment up to 5,500 m. Integrated heat exchangers from Webasto are suitable for using residual engine heat to heat the cabin. Various models offer heating outputs from 3.3 to 6.6 kW. 

 

Water heaters are integrated into the vehicle's coolant circuit. Once the coolant is warm, air is heated, which then flows into the passenger compartment via the vehicle fan. In addition, the heaters can preheat the vehicle engine so that it starts more easily and requires less fuel.

Webasto water heaters for agricultural machinery are available with 5 to 15 kW heat output.

Heating solutions for electric agricultural machinery 

Webasto offers extremely efficient high-voltage heaters (HVH) with heating outputs between 5 and 12 kW for battery electric vehicles. With their clever stratified heating technology, the HVHs convert direct current into heat with virtually no loss. All models are ISO 21434-compliant, but differ in terms of voltage, communication interfaces and service life. Thanks to their extremely compact design, the HVHs require very little installation space. They can heat both the cabin and the vehicle batteries, increasing their service life and extending charging cycles.

Key facts

  • Efficient heating layer technology

  • Extremely compact design

  • No rare earths

  • Increase battery service life and extend charging cycles 

  • Flexible installation positions

  • Long service life between 12,000 and 25,000 operating hours
