Airrex AH-500i Diesel Infrared Heater

The Airrex AH-500i is a next-generation 15 kW diesel infrared heater designed for professional heating of spaces up to 1,500 m³. Featuring the new Blue Flame Burner technology and selectable 11 kW or 15 kW heating output, it delivers clean, efficient and comfortable infrared heat for workshops, warehouses, industrial facilities, construction sites and agricultural buildings.

Unlike conventional fan heaters, the AH-500i uses infrared radiation to heat people, machinery and surfaces directly, providing even, comfortable 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 match the heating output to your requirements for improved efficiency.

Designed for reliable everyday use, the heater operates on renewable diesel (HVO) or conventional diesel and features a 45-litre fuel tank for extended operating time. The automatic thermostat maintains the selected temperature while optimizing fuel consumption, helping reduce operating costs without compromising heating performance.

Built-in WiFi connectivity enables remote monitoring and control through the Rex Nordic mobile app, with optional 4G connection available where WiFi is not accessible. The intuitive soft-touch LED control panel makes operation simple, while the quiet 47 dB operating noise, comprehensive safety systems and 5-year warranty after product registration make the AH-500i a dependable heating solution for demanding professional environments.
