AIRREX AH-800i Diesel-Infrared 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.

Advanced smart controls set this heater apart, featuring WiFi connectivity and optional 4G network connection that allows remote operation through the dedicated Airrex mobile app, available on both Android and iOS platforms. The 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.
