22kW Infrared Radiant Heater – The Airrex AH-800i is a powerful 22 kW diesel-infrared heater designed for very large spaces up to 2000m³, making it ideal for industrial warehouses, manufacturing facilities, large construction sites, and heavy-duty commercial applications. This robust industrial unit operates on renewable diesel (HVO), standard diesel, or red diesel with a fuel consumption of 1.71 to 1.9 liters per hour during continuous heating, though the automatic thermostat typically reduces actual consumption significantly in real-world use, while its substantial 70-liter fuel tank ensures extended operation for the most demanding applications.

22kW 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 22 kW heating capacity, the AH-800i operates quietly at just 48 dB and requires minimal electrical power at only 80 watts. Measuring 130 x 35 x 134 cm and weighing 81 kg, this heater combines maximum industrial performance with practical functionality for the most challenging heating environments.
