Heatmax's fan coil unit, which is the indoor component of an air conditioning system, transfers heat or cooling to the space by supplying it with water at the appropriate temperature. In Greek, it is referred to as a forced air circulation body. Its operation is based on forced air circulation created by the fan it contains.

Its main features include:

• Heat distribution: Heat is distributed throughout the space with the help of a fan, as opposed to simple radiator units.
• Connection: It can be connected to a heat pump or boiler for heating and cooling all year round.
• Installation: The unit is installed on the ceiling of the room, embedded in a false ceiling or freely.
• Air exhaust: Air discharge is only from the installation point, unlike ducted air conditioners.
