Heating solutions for
oil and gas industry vehicles

Relaxed driving in autumn and winter thanks to parking heaters for diesel and petrol vehicles or high-voltage heaters for electric cars 

The reliable heating solutions from market leader Webasto turn your car into a feel-good oasis even in cold months. Whether it runs on electricity, petrol or diesel, we have the right heater for every drive. For retrofitting, there is the classic fuel-powered parking heater or a variant that uses electricity from the socket. For original equipment manufacturers, we offer tailor-made solutions for both fuel-powered devices and high-voltage heaters in electric vehicles.

 

Enjoy getting into a pre-heated car and driving off immediately, without a coat, gloves or scarf and without having to scrape the windows clear first! What's more, misted-up windows are a thing of the past and you always have a clear view. This increases safety, saves time and provides relaxation not only in the morning. Another advantage: the engine is also preheated. This reduces wear from cold starts and saves emissions.

 

You can choose how you want to operate the heating - directly, by remote control or by app. Our ThermoConnect app offers most of the functions. You can easily find a Webasto partner near you in our dealer search.

Fuel-operated heaters for oilfield vehicles

Webasto coolant heaters are designed to efficiently pre-condition engines and essential fluids before operation. By pre-heating the engine, they significantly reduce idle times, eliminate cold starts, and lower fuel consumption while minimizing wear on critical components. When combined with a fluid heat exchanger, these systems ensure that hydraulic fluids, engine oil, diesel tanks, and transport fluid systems are ready for immediate use. Additionally, they help prevent DEF freeze-up and reduce the need for DPF maintenance, all within a compact and versatile design.

Complementing this, Webasto air heaters provide reliable, on-demand comfort for operators. They deliver instant warm airflow inside vehicle cabs or workspaces without requiring the engine to run, drastically reducing idle time and conserving fuel. With efficient performance, these heaters can operate for up to 22 hours on less than one gallon of fuel. Their quiet operation, fast return on investment, and advanced SmarTemp Control 3.0 with Bluetooth capability enable convenient remote control and diagnostics.

 

Together, Webasto air and coolant heaters form a comprehensive heating solution for oilfield trucks, frac support vehicles, and off-highway equipment—helping operators save thousands annually in fuel costs and maintenance while ensuring optimal performance and comfort.
