Working principle of Air Heaters

An Air heater generate clean hot air. Steam and thermic fluids are the heating media. The heating media will be passing through tubes stacked in the air heater. Fins made of Aluminium / Stainless steel / GI will be assembled in the tubes. These fins are heat transferring media.
Atmospheric air will be passing through the fins . Atmospheric air will be guided through ducting. The heated fins will transfer heat to atmospheric air when air comes in to contact with fins.
The hot air will be taken to the user point through ducts.
