The air heating unit worms the air using the heat of hot or overheated water or steam coming from external sources of heat supply and is designed for air heating (including standby heating) of industrial premises, the technological process of which is not accompanied by any release of dust or explosive gases.
The unit should be operated in areas with a temperate climate. The heat transfer agent temperature should not be higher than 180°C and the pressure should be not higher than 1.2 MPa.
Principle of operation:
When the fan is in operation, the air is taken from the room and heated up as it passes through the air heater. Air heater consists of finned tubes with working media hot water or steam. Then it is ducted through the fan working wheel blades into the heated area.
If heat transfer agent change on cool fluid then the unit works as cooling equipment.
