Hitachi Europe adds to its VRF air-conditioning range
Hitachi Europe has extended its Set Free range of VRF air-conditioning with a system that can operate in 3-pipe heat-recovery or 2-pipe heat-pump mode. Outdoor units in the FSXN range can be installed singly or in multiple from 8 to 54 hp. They can be teamed up with 10 types (52 models) of indoor unit. Maximum piping length has been increased to 165 m and all outdoor units can be transported in an elevator, including the largest 18 hp model.
A noise-reduction mode enables noise levels to be reduced at certain times of day. There is also a back-up function that prevents a system from stopping completely if one outdoor unit in a group fails.
FSXN units have DC inverter compressors. Cooling capacity is controlled automatically according to demand without the need for signal wiring.
