Mobile Warm Air Heaters M

Efficient heating and drying on all construction sites

Kroll's M mobile warm air heaters supply a wide variety of areas with targeted heat quickly and efficiently. They are particularly suitable for tent heating at events, for additional hall heating, as well as for construction heating and the associated drying and frost-free maintenance. Thus, even in the winter months, new buildings, renovations or modernizations can be carried out without delay. Thanks to their compact design and high mobility, the units can be quickly deployed wherever temporary heat is required, even as emergency or transitional heating.

Thanks to the integrated oil tank and heating cartridge, the smaller models M25, M50 and M70T are space-saving and ready for immediate use when stocked with fuel. The larger models M70, M100, M150, M200 are also quickly ready for operation thanks to a drum fitting and a heated oil filter. Thanks to additional swivel castors, crane lugs and forklift mounts, maximum mobility is guaranteed. The choice of fuel is up to you; the units have both oil and gas burner approvals.

The efficiency is 93% (Hi), which is an excellent value for mobile hot air generators.

Burner connection for oil, natural gas, LPG and universal oil burners
Heated oil filter
Combustion chamber and heat exchanger made of stainless steal 1.4512
Lenkrollen ab M70
Radial fan with press capacity up to 180 Pa
Room thermostat connection

The integrated high-performance centrifugal fans have a pressing capacity of up to 180 Pa and are specifically aimed at connecting hot-air hose systems. This means that even long supply distances or heating from outside are no problem. This ensures effective heating even when the unit is installed outdoors. With the optional recirculation module (factory-integrated on M150/M200), efficient and economical operation is guaranteed.

High-quality components, such as the stainless steel combustion chamber and the stainless steel heat exchanger with approx. 15% chrome content, guarantee a long service life. All fittings and control elements are designed to be service-friendly, so that maintenance can be carried out conveniently.

We guarantee the quality of our products - As the first manufacturer in the heating and ventilation sector, we offer our customers a full 3-year manufacturer's warranty.
