Fuel-fired heaters are essential in industrial process facilities and heavy-duty construction, delivering dependable heat where electric systems fall short. They’re widely used in trucks, off-highway equipment, marine applications, and buses operating in extreme conditions.
These systems use insulated enclosures to safely transfer heat from fuel combustion into fluid-filled coils. Heater and coil configurations vary by industry, application, and performance requirements, ensuring the right solution for the job.
Polar Mobility field-fired heaters are built for durability, straightforward installation, and full compliance across North America.
Polar Mobility’s fuel-fired heaters are designed to deliver dependable heat in demanding industrial and commercial mobile environments. These robust systems use diesel or gasoline to generate consistent, efficient heat where electrical systems aren’t practical or reliable.
Eberspächer heaters are among the most reliable and efficient climate control solutions for commercial mobile equipment. These systems are designed for engine-independent operation and deliver consistent cabin and system heat across a wide range of applications, including:
By operating independently of the engine, Eberspächer heaters significantly reduce idling time—helping lower fuel consumption, emissions, and operating costs while keeping crews comfortable in cold conditions.
The Dometic Proheat X30 is a diesel-fired auxiliary heater built to handle harsh winter conditions. With 31,000 BTU/hr of fluid-heating capacity, it delivers reliable, efficient heat to enhance equipment operation and operator comfort.
Ideal for heavy-duty and off-highway applications, Proheat coolant heaters help reduce idling, improve cold-weather performance, and lower overall operating costs, all while maintaining industry-leading durability.
The Proheat X30 features four intelligent operating modes:
General Component specializes in engine coolant and air heaters for sleepers, boats, RVs, and vehicle cabs. Their fuel-fired heating systems operate independently of OEM vehicle systems and are available in gas or diesel configuration.

Direct fuel-fired heaters expose the flame directly to the air, making them more efficient and suitable for heating large, well-ventilated spaces such as warehouses or construction sites.
In contrast, indirect fuel-fired heaters heat air through a heat exchanger, making them ideal for indoor spaces or areas where combustion by-products must be kept out of the air stream. These heaters are typically used in more enclosed or sensitive environments where maintaining air quality is essential.
Eberspächer heating units are among the highest-quality heating solutions available today.
Choosing the appropriate mobile equipment heating solution for a construction site or industrial application involves evaluating several key factors. These include:
Proper assessment of these criteria helps you achieve efficient, effective heating tailored to the site’s or industry’s specific needs.
