Product Description
The AIRREX AH-500i Blue Flame WiFi Infrared Diesel Heater is a high-performance mobile heating solution designed for professional and commercial environments where reliable, efficient heat is essential. Ideal for workshops, garages, warehouses, agricultural buildings, industrial units and large open workspaces, the AH-500i delivers powerful infrared heating with exceptional fuel efficiency.
Utilising advanced Blue Flame burner technology, the AH-500i produces clean, efficient infrared heat while operating with low noise levels, reduced odour and lower emissions compared with conventional mobile diesel heaters. Rather than simply warming the surrounding air, infrared heat is directed towards people, machinery, tools, walls and floors, making it particularly effective in larger spaces and areas where doors are frequently opened.
Featuring a dual-power output of 11kW to 15kW, the heater automatically adjusts its performance to match heating demand, helping to maintain a comfortable working temperature while optimising fuel consumption.
Integrated WiFi connectivity allows convenient remote control via the AIRREX mobile app. Users can monitor and adjust temperature settings, view operating notifications and check fuel levels directly from a smartphone or tablet, providing greater flexibility and control in busy working environments.
The AH-500i operates on biodiesel, renewable diesel or standard diesel, offering excellent fuel flexibility. Combined with its generous 45-litre fuel tank, compact footprint and fully mobile design, the heater is an ideal choice for demanding commercial and industrial heating applications.

Cleaner Combustion Technology
Blue Flame burner technology promotes cleaner, more efficient combustion, helping to minimise odours, smoke and airborne dust while improving overall operating efficiency.
Automatic Heat Adjustment
The intelligent dual-power system automatically adjusts output between 11kW and 15kW according to heating demand, helping reduce fuel consumption while maintaining a consistent temperature.
Remote WiFi Control
Built-in WiFi connectivity enables convenient remote operation through the AIRREX mobile app, allowing users to monitor temperature, view system notifications and check fuel levels from virtually anywhere within network range.
Mobile and Practical Design
With its compact upright construction, integrated fuel tank and robust mobile design, the AH-500i can easily be positioned wherever heat is required.
