Airrex AH-900i Diesel Infrared Heater

The Airrex AH-900i is the most powerful heater in the Airrex range, delivering up to 24 kW of infrared heat for spaces up to 2,500 m³. Designed for demanding industrial environments, it combines the latest Blue Flame Burner technology with selectable 19 kW or 24 kW heating output to provide exceptional performance and fuel efficiency in large warehouses, industrial halls, workshops and construction sites.

Unlike conventional fan heaters, the AH-900i uses infrared radiation to heat people, machinery and surfaces directly, providing comfortable, even warmth without unnecessary air movement or dust circulation. The new Blue Flame Burner ensures exceptionally clean combustion with ultra-low emissions, while Dual Power technology allows you to adjust the output to suit changing conditions and reduce fuel consumption whenever full power is not required.

Built for continuous heavy-duty use, the heater features a large 70-litre fuel tank and runs on renewable diesel (HVO) or conventional diesel. The automatic thermostat optimizes fuel consumption to reduce operating costs, while built-in WiFi connectivity enables remote control through the Rex Nordic mobile app (with optional 4G). Despite its immense 24 kW capacity, the AH-900i operates at a quiet 48 dB and features comprehensive safety systems and a 5-year warranty.
