No exhaust pipe. No diesel smell. Airrex diesel infrared heaters deliver powerful, efficient heating for large spaces using clean-burning technology that eliminates every downside of traditional diesel heating.
Our advanced triple combustion process burns fuel so cleanly that over 99% of the exhaust is harmless CO2 and water vapor. This means odorless, smoke-free operation, perfect for warehouses, workshops, construction sites, and agricultural buildings where air quality matters most.
With heating capacities from 13-22 kW while consuming just 0,9-2,2 liters of fuel per hour, these heaters provide exceptional value for large spaces up to 2000 m³ where electric power is limited or expensive. The ceramic-coated heat exchangers operate quietly at only 48 dB while distributing infrared heat evenly in all directions.
Airrex heaters run on standard diesel or renewable HVO fuel, raising indoor temperatures up to +40 °C even in extreme cold. Available in three sizes with a 2-year warranty that extends to 3 years when you register online.
The perfect solution for heating large open spaces with energy efficient low fuel consumption and maximum heat performance.

Airrex heaters use infrared radiation, which heats objects and surfaces directly, not the air. This means the warmth is evenly distributed, comfortable, and not lost to ventilation or open doors.
The heater burns diesel cleanly inside a patented catalytic combustion chamber. There’s no visible flame, no smoke, and no smell, making it safe for indoor use without an exhaust pipe
Airrex has no fan. This means silent operation and no dust circulation, which is ideal for clean environments like workshops, inspection stations, or retail spaces.
You can set the desired temperature between 0 and +40 °C. The built-in thermostat continuously monitors and maintains it, starting and stopping automatically to optimize fuel and energy use.
