With the advanced burner system, the Airrex diesel heater has a patented oil burner with an electric fuel pump that circulates the combustion gases through pipelines with ceramic coating and creates heat as infrared radiation. The triple combustion process ensures complete and clean combustion. Normal ventilation is sufficient. An effective silencing system inside the exhaust pipe compresses and expands the exhaust gases which makes Airrex very quiet – only 48 dB.

Heater with remote control
The Airrex AH-800i can be controlled remotely from anywhere in the world via the Airrex app. In the app, you can see in real time, for example, the temperature of the heated space, the amount of fuel and whether the heater is running right now. Any error messages are also displayed in the app. You can now control the heater as if you were physically next to the device, with the exception that a device that is completely shut down cannot be started by remote control. The heater can be connected to an existing Wi-Fi network. However, in the absence of a Wi-Fi network, it can be connected directly to the mobile phone network using an optional plug-in device.
New control panel
The control panel for Airrex heaters has also been completely rebuilt. It is now futuristically metallic, a perfect match for the darker graphite grey heater. The redesigned control panel is built to work together with the mobile app – both functionally and visually. One of the great things about the new control panel with its mirror-like surface is its ability to cope with power outages! After a power outage. The device will continue to operate with the same settings as before the outage.
Sealed cap and stronger protective grid
When the fuel tank was redesigned, the fuel cap was also replaced with a fully sealed model that prevents fuel spillage when moving the heater. In addition, the grid protecting the ceramic piping has been reinforced and improved.
The Airrex AH-800i is a high-capacity diesel infrared heater designed for large agricultural buildings, workshops and industrial spaces up to 2000m³. Combining powerful output with advanced burner technology and smart connectivity, it delivers efficient, clean and ultra-quiet heating.
Featuring a patented oil burner with electric fuel pump, combustion gases circulate through ceramic-coated pipelines to produce comfortable infrared heat. The triple combustion process ensures complete and clean burning, while normal ventilation is sufficient.
An integrated silencing system compresses and expands exhaust gases internally, keeping noise levels to just 48 dB. With no fan, no dust and no smell, the AH-800i provides consistent radiant heat without air movement.
Wi-Fi connectivity is standard, with optional 4G capability for full remote access via the Airrex mobile app. Users can monitor temperature, fuel levels, operating status and error messages in real time. The heater automatically restarts after power outages, maintaining previous settings.
Finished in dark graphite grey, the AH-800i features a redesigned burner system, reinforced protective grid, sealed fuel cap to prevent spillage, integrated wheels for mobility and a 3-year warranty.
