Why Choose the AIRREX AH-500i Infrared Heater?
Efficient & Targeted Infrared Heat Unlike conventional space heaters that waste energy warming the surrounding air, the AIRREX AH-500i uses direct infrared radiation. It heats people, machinery, tools, and structural surfaces directly. This targeted warmth remains highly effective even in large, draughty workspaces or buildings where large shutter doors are frequently opened.
Advanced Blue Flame Burner Technology The newly engineered Blue Flame Burner ensures exceptionally clean combustion with ultra-low emissions and drastically reduced odour. Operating at a quiet 47 to 50 dB, it delivers a highly comfortable working environment without the disruptive roar or airborne dust circulation common with traditional fan-assisted mobile diesel heaters.
Eco-Friendly & Flexible Fuel Options Engineered for reliable everyday use, the AH-500i offers total fuel flexibility. It operates seamlessly on renewable diesel (HVO), biodiesel, or conventional standard diesel. Its generous 45-litre fuel tank combined with an intelligent automatic thermostat ensures extended running times and highly optimised fuel consumption.
Smart WiFi Connectivity & Remote Monitoring Stay in full control of your climate from anywhere. Built-in WiFi connectivity links directly to the Rex Nordic mobile app (with optional 4G connection available for remote sites). Use your smartphone or tablet to effortlessly adjust temperature settings, monitor fuel levels, and receive real-time system notifications.
