What Makes the 2026 AIRREX AH-500i a Game-Changer?
Traditional space heaters rely on blowing massive amounts of expensive, warm air around a room—energy that is immediately lost the moment a roller shutter door is opened. The AH-500i flips this concept on its head using advanced infrared radiation.
1. Targeted, Dust-Free Warmth
Instead of heating the air, the AH-500i projects waves of infrared energy that directly heat people, tools, machinery, and surfaces. This creates a comfortable working environment within minutes, even in draughty, high-ceilinged industrial buildings. Because there is no internal fan blowing air around, it operates without creating disruptive dust circulation or noise (running at a quiet 47–50 dB).
2. Revolutionary Blue Flame Burner Technology
At the heart of the new 2026 model is the Blue Flame Burner. This advanced combustion system ensures complete, incredibly efficient fuel burn. The result? Exceptionally low emissions, virtually zero odour, and smoke-free operation. In fact, when used in accordance with manufacturer guidelines in spaces with natural ventilation, no separate exhaust pipe or flue is required.
3. Future-Proof Fuel Flexibility (HVO Compatible)
In alignment with modern environmental standards, the AH-500i runs flawlessly on renewable diesel (HVO), as well as standard diesel or biodiesel. By switching to HVO fuel, businesses can slash their heating carbon footprint by up to 90% while still enjoying powerful 11kW to 15kW dual-power performance.
4. Smart WiFi and 4G Remote Control
Managing a busy facility just got easier. The AH-500i features integrated WiFi connectivity, linking directly to the Rex Nordic mobile app. From your smartphone or tablet, you can remotely:
- Turn the heater on or off to pre-warm your workshop before the team arrives.
- Adjust target temperatures between 0°C and 40°C.
- Check real-time fuel levels of the generous 45-litre tank.
- Receive system and safety notifications instantly.
Ideal for Large Commercial & Agricultural Spaces
Capable of effortlessly heating open spaces up to 1,500 m³, the AH-500i is engineered specifically for demanding, professional environments including:
- Commercial Garages & Body Shops
- Industrial Warehouses & Logistics Hubs
- Agricultural Buildings & Livestock Sheds
- Large Open-Plan Workshops & Factories
