Condensing industrial warm air heaters IH/AR K

Warm air heaters for industry floor standing

Ecotech condensation technology

The most efficient system for the production of heat that recovers part of the latent heat of the smokes before they are expelled.

High Performance Heat Exchanger Heat Exchanger

Suitable for aggressive and dirty environments even with high temperatures. Standard or customized configuration.

Ambient air control

Suitable for heating but also for introducing large quantities of fresh air filtered or cooled. Useful for compensation, in industrial environments with strong air extraction.

Electromechanical and electronic regulation

2-stage or modulating operation with advanced devices for the control and safety of the system.

High efficiency inverter

It saves energy by automatically adjusting the air flow during the operation of the ventilation system.

Pictures are for illustration purposes only.

Details

The IH/AR K air generators are suitable for heating both small rooms and large rooms.

The main element is the indirect heat exchanger with through flame, with 3 turns of smoke in stainless steel AISI 441 which, in combination with a two-stage or modulating burner with low NOx class 3, guarantees a very high efficiency and an ecological combustion.

Suitable for condensing operation, they achieve up to 105% efficiency, in operation at 30% partial load. They are equipped with centrifugal fans of high strength and quality that guarantee a high flow and air pressure output.

These devices are extremely flexible, which can introduce air into the environment through direct diffusion terminals or through a channeled distribution.
