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) or standard 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.
Advanced smart controls set this heater apart, featuring WiFi connectivity and optional 4G network connection that allows remote operation through the dedicated Rex Nordic mobile app, available on both Android and iOS platforms. The intuitive soft-touch control panel with LED screen provides easy local operation.
emperature 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.
