Helicoidal gas air heater AH 80

AH 80 axial fan heater natural gas G20 or propane gas G31 – SEET

The AH 80 axial fan heater, operating on natural gas G20 or propane gas, is an efficient heating solution designed to provide controlled thermal comfort in large or high-ceiling professional buildings.

Developed to meet current regulatory requirements, the device complies with the ErP 2021 directive. It comes in five versions, covering a power range from 13 to 80 kW. Its two-stage heating operation allows for precise adjustment of heat distribution according to needs, without using condensation operation.

Efficient combustion and emission control

The AH 25 is equipped with a high-efficiency multi-flame burner, NOx Class 5 rated, ensuring low pollutant emissions and reliable combustion. The two-stage gas solenoid valve modulates power to 52% or 100%, ensuring a gradual temperature rise. The sealed combustion, combined with automatic ignition, enhances safety and operational stability.

Heat exchange and air diffusion

The seamless, four-pass tubular heat exchanger has a thickness of 1.5 mm, ensuring excellent heat transfer and high durability. The axial fan with crescent blades provides homogeneous distribution of hot air, even in large volumes.

Easy installation and regulation

Designed as a self-contained heating system, the AH 25 gas-fired air heater can be installed with a balanced flue, on a facade or on a roof. Its electronic board compatible with pilot wire simplifies regulation and integration into existing thermal management systems, while ensuring precise control and rapid implementation.
