15kW Infrared Radiant Heater – The Airrex AH-300i is a powerful 15 kW diesel-infrared heater designed for larger spaces up to 1500m³, making it ideal for warehouses, large workshops, construction sites, and industrial applications. This robust unit operates on renewable diesel (HVO), standard diesel, or red diesel with a fuel consumption of 1.14 to 1.33 liters per hour during continuous heating, though the automatic thermostat typically reduces actual consumption significantly in real-world use, while its substantial 45-liter fuel tank ensures extended operation for demanding applications.

15kW Infrared Radiant Heater has an intuitive soft-touch control panel with LED screen provides easy local operation.

Temperature management is precise and flexible, with automatic thermostat control adjustable from 0 to 40°C, ensuring optimal comfort while maximizing fuel efficiency. Additional convenience features include a programmable stop timer up to 24 hours and an interval timer that cycles between 5-60 minutes of operation with 5-minute breaks.

Despite its substantial 15 kW heating capacity, the AH-300i operates quietly at just 48 dB and requires minimal electrical power at only 80 watts. Measuring 95 x 31 x 101 cm and weighing 46 kg, this heater combines professional-grade performance with practical portability for industrial environments.
