Gas-fired helical air heater AH 35

AH 35 helical air heater natural gas G20 or propane gas G31 – SEET

The AH 35 helical air heater, operating on natural gas G20 or propane gas, is a high-performance heating solution designed to ensure controlled thermal comfort in high-rise or high-volume 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 requiring 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 at 52% or 100%, ensuring a gradual temperature rise. Sealed combustion, combined with automatic ignition, enhances safety and operational stability.

Heat exchange and air distribution

The seamless, four-pass tubular heat exchanger is 1.5 mm thick, ensuring excellent thermal transmission and high durability. The helical fan with crescent-shaped blades allows for homogeneous distribution of hot air, even in large volumes.

Easy installation and regulation

Designed as a self-contained heating system, the AH 25 gas air heater can be installed in 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.
