Airrex AH900i 24kW Infrared Diesel Heater

The Airrex AH900i is a portable infrared diesel heater for large industrial workspaces that are typically hard to keep warm during the winter. It features a 19kW and 24kW dual-stage heating output, which is ideal for heating large spaces up to 2,500m³. We are now recommending this 24kW heater for workshops, warehouses, and garages, as well as marquee hire companies, events companies and venues.

Succeeding the AH900i

The AH900i is replacing the Airrex AH800i and is now the flagship model in the Airrex AH range. New features include improved burner technology, refined digital controls, and low-noise running levels which offer users a straightforward replacement to the legacy Airrex AH800i.

Features & Benefits: Airrex AH900i

Dual Heating Output: With two heat settings available, users can easily switch between 19 kW (64,800 Btu/h) and 24 kW (81,900 Btu/h) for quick heating or maintaining temperatures throughout the day.
Heating Capacity: This model is capable of heating industrial spaces up 2,500 m³, depending on layouts and insulation levels. Ideal for warehouses, workshops, agricultural buildings, and events providers.
Infrared Technology: Long-wave infrared heat works by heating objects and people instead of just heating the air. It does this without creating noise, drafts, or wasting heat on high ceiling air.
Low-Noise Running: At just 48 dB to 51 dB, it features a very low operating noise level for its class. This is essential for not disturbing workers during the day or at busy events in public areas.
Sustainable Fuels: Cutting carbon emissions by up to 90%, it works with the environmentally-friendly renewable diesel HVO100 l (EN 15940) and is also compatible with regular EN 590 diesel.
Fuel System: The AH900i can provide heat for an entire shift due to the large 70-litre fuel tank that can last for around 30 to 39 hours.
Smart App & Remote Control: With the built-in Wi-Fi and 4G connectivity you can control heat settings and receive alerts straight to your phone via an app, ideal for controlling when off site.
Up to 5-Year Warranty: The warranty can be extended from the standard 2-year to a 5-year warranty when registered with Rex Nordic. Free registration must be completed within the first 4 weeks after purchase.
