General description

The air heater unit consists of a fan, motor and heat 
exchanger and it is used to heat air with water. The water 
circulates in the air heater unit’s heat exchanger and 
heats the air with the help of the fan. The air heater unit 
can be fi tted with various accessories to control the supply 
of heat. Its low external height ensures that it can be 
installed in premises with varying roof heights.
