Sideflow Heat Pump - FSNM

Sideflow Heat Pump – FSNM offers a compact alternative to traditional vertical discharge VRF. A twin fan horizontal airflow unit provides the most economical use of plant space, even allowing the option of a wall mounted VRF system.

A reduction in materials results in a reduced cost, whilst still maintaining the excellent performance and reliability expected of Hitachi VRF systems, with COP’s of up to 4.24.

Heat Pump/Recovery FSXN & FSXHN

Set Free VRF 2-pipe heat pump or 3-pipe heat recovery is available from a single unit to adapt to customer requirements as they change. Each outdoor unit is lightweight and modular which – combined with long piping runs and improved height difference – means Set Free VRF can meet any design brief. Available in cooling and heating capacities from 22.4 kW to 165 kW in standard model and 14 kW to 100 kW in High Efficiency model.

Lower energy consumption

By means of the frequency inverter with Hitachi exclusive control and advanced optimisation software, the system connects, controls and manages its operation accurately. So it adjusts flow from the outdoor unit automatically depending on the number of indoor units in service, thus achieving significant energy savings.
