The Airrex AH-500i is a new generation 15 kW diesel infrared heater designed for professional heating of spaces up to 1,500 m³. With the new Blue Flame Burner technology and adjustable heating output of 11 or 15 kW, it delivers clean, efficient, and comfortable infrared heat for workshops, warehouses, industrial sites, construction sites, and agricultural buildings.
Unlike conventional fan heaters, the AH-500i heats people, machines, and surfaces directly with infrared radiation — even, comfortable heat without unnecessary air movement or dust circulation. The new Blue Flame Burner ensures exceptionally clean combustion with very low emissions, while Dual Power technology allows the power to be tailored to the needs for higher efficiency.
The heater is designed for reliable daily use, runs on renewable diesel (HVO) or regular diesel, and has a 45-liter fuel tank for extended operating time. The automatic thermostat maintains the selected temperature while simultaneously optimizing fuel consumption, reducing operating costs without compromising heating performance.
Built-in WiFi enables remote monitoring and control via the Rex Nordic mobile app , with optional 4G connection where WiFi is unavailable. The intuitive soft-touch LED control panel makes operation simple, and thanks to its quiet 47 dB operation , extensive safety systems, and 5-year warranty after product registration, the AH-500i is a reliable heating solution for demanding professional environments.
