Hitachi adds to its Set Free VRF range
Hitachi has extended its VRF range of 2-pipe heat-pump and 3-pipe heat-recovery systems with the Set Free FSXN1E outdoor units. These units are available in ratings from 8to 54 hp and are fully compatible with the whole range of System Free indoor units, including the recently introduced 0.6 hp units.
Features include a new compressor with improved performance at low speed and optimised R410A refrigerant cycle contributing to high seasonal efficiency. Hitachi claims that these units have the lowest refrigerant charge on the market.
Up to 64 indoor units can be connected to one outdoor unit, with unlimited linear or radial-design main piping branches.
