Rex Nordix Airrex AH-500I Diesel Infrared Heater

Powerful Infrared Heating for Large Spaces The Airrex AH-500i delivers up to 15kW of professional infrared heating for spaces up to 1,500m³. Instead of simply warming circulating air, infrared radiation transfers heat directly towards people, machinery and surrounding surfaces. This makes it ideal for demanding commercial and industrial environments. Two Heating Outputs in One Heater Dual Power technology lets you select between 11kW and 15kW heating output. Use full power when rapid, high-capacity heating is required, or reduce the output when conditions demand less heat. This flexibility helps match heating performance more closely to the space. Advanced Blue Flame Burner At the heart of the AH-500i is Airrex's new Blue Flame Burner technology. It is designed to provide exceptionally clean combustion with ultra-low emissions. This combines powerful professional heating with efficient everyday operation. Comfortable Infrared Warmth Unlike conventional fan heaters, the AH-500i uses infrared radiation to deliver warmth directly where it is needed. This reduces unnecessary air movement and helps minimise the circulation of dust. The result is comfortable, even heating without relying on powerful warm-air distribution. Built for Professional Environments With coverage up to 1,500m³, the AH-500i is suited to workshops, warehouses, manufacturing facilities and industrial halls. It can also provide powerful heating for construction sites, event tents and agricultural buildings. Its robust 47kg construction is designed for demanding professional applications. Extended 45-Litre Fuel Capacity A large 45-litre fuel tank provides extended operation between refills. Fuel consumption ranges from approximately 1.05 to 1.42 litres per hour depending on operation. This makes the heater well suited to applications requiring dependable heating over longer periods. Renewable Diesel Compatible The AH-500i can operate using conventional EN 590 diesel or renewable HVO100 meeting EN 15940. This gives businesses greater flexibility when selecting their preferred fuel. The heater therefore combines professional performance with modern fuel compatibility. Automatic Temperature Control Set your desired temperature between 0°C and 40°C and allow the automatic thermostat to manage operation. The system optimises heater operation to maintain the selected temperature while controlling fuel consumption. This reduces the need for constant manual adjustments. Control Your Heating Remotely Built-in WiFi connects the AH-500i to the Rex Nordic app on compatible Android and iOS devices. This allows convenient remote monitoring and control without needing to remain beside the heater. An optional 4G connection can also be used where WiFi is unavailable. Flexible Timer Controls A 24-hour stop timer provides greater control over how long the heater operates. There is also a selectable 5 to 60-minute interval timer. Together, these controls make it easier to tailor heating around working hours and changing requirements. Quiet Professional Performance Despite its substantial heating capacity, the AH-500i operates at just 47dB. This makes it particularly useful where excessive heater noise could become distracting. You get powerful heating without the noise typically associated with high-output fan-driven equipment. Designed With Safety in Mind Comprehensive safety systems provide additional reassurance during everyday professional use. These include tilt detection, overheating protection and automatic shutdown functionality. A soft-touch LED control panel also keeps operation straightforward and intuitive. Low Electrical Power Requirement Although it produces up to 15kW of heating, maximum electrical consumption is only 50W. The heat itself is generated from the fuel rather than a 15kW electrical heating element. This allows substantial heating performance from a standard 230V, 50Hz electrical supply. Five-Year Registered Warranty The AH-500i is backed by a five-year warranty when the product is registered. This provides additional reassurance for businesses investing in a heater for regular professional use. Registration is required to receive the stated five-year warranty.
