Johnson Controls Hitachi Air Conditioning Launches New Market-Leading VRF

Johnson Controls Hitachi Air Conditioning Europe is launching an innovative new range of modular VRF units for 2018 under the Hitachi brand. Called Set Free Sigma, the outdoor units for 2-pipe Heat Pump and 3-pipe Heat Recovery will replace the existing Set Free VRF units and will be produced in the company’s European manufacturing facility in Spain.

New and extended line up


Available from 5 to 24HP in a single unit module and up to 96HP with combinations, the outdoor unit casing has been completely redesigned and offers a total of seven new capacity models - 18, 20, 22 and 24HP (Standard) and 14,16 and 18HP (High Efficiency). This extended lineup achieves higher power combinations from fewer units, requiring fewer connections and delivering improved installation flexibility - meeting the needs of specifiers, installers and end users.

150% combinability


All units are compatible with Hitachi’s System Free indoor range, with comfort (cold draught) protection available as standard across the range. The High Efficiency FSXNPE model combinability ratio has been extended to 150% with up to 64 connectable 0.4HP or 0.6HP indoor units.

Low environmental footprint

Using R410A refrigerant, the full Hitachi Sigma VRF range benefits from a new high efficiency DC inverter compressor for precise control by 0.1Hz increments which achieves a 4.6% increase in seasonal efficiency over previous models. Combined with a new fan design, bell-mouth fan housing and sigma-shape heat exchanger, the Set Free Sigma VRF range achieves improved efficiency even at low or partial load in cooling operation, with performances increased to achieve SEER up to 8.33 and SCOP up to 5.06.
Perfect for the Bulgarian market, the new Hitachi Sigma VRF models deliver increased installation flexibility combinations and extremely long pipings.

Hitachi’s new Set Free Sigma VRF range is available from Hitachi’s official distributor for Bulgaria – TANGRA AV Ltd.
