Heatmax fan coil unit, an indoor system component of air conditioning that transfers heat or cooling to the space by supplying water at the appropriate temperature. The term forced air circulation body refers to its operation, which is based on the forced circulation of air by the built-in fan.

Heat is distributed throughout the space with the help of the fan, unlike simple radiators where distribution occurs passively. It can be connected to a heat pump or boiler, providing heating and cooling all year round. It is installed on the floor without a cover, recommended for installation in concealed areas of the space for aesthetic reasons. It has high efficiency in cooling and is an ideal choice for space heating, as warm air is lighter than cold air.
