The FCL cassette type fancoil is a terminal for the conditioning of air in a room. The unit concentrates high technological and functional features that make it ideal for air conditioning all environments. The supply of conditioned air is distributed throughout the room. The unit generates heat if included in a heating system with a boiler or heat pump but may also be used in the summer as an air conditioner if the heating system has a water chiller. The unit is mounted in a suspended-ceiling with the possibility of sending conditioned air to adjacent rooms and introducing external air independently from unit ventilation. The basic FCL unit is available in two versions, for two pipe and four pipe systems.
