High efficiency Set Free VRF

FSXNH-CGIClaiming to be the only manufacturer with a 2-pipe heat pump and 3-pipe heat recovery VRF from a single unit, Hitachi has gone one step further introducing Set Free FSXN1E to its expanding range.

The FSXN1E is available from 8hp to 54hp and is fully compatible with the full range of System Free indoors – including the new 0.6hp units – allowing a greater number of connectable indoor units than ever before, achieving complete design and installation flexibility.

A new compressor with improved performance at low speed and optimised R410A refrigerant cycle is said to contribute to the high seasonal efficiency values.

Height differences between outdoor/indoor units are up to 90m and up to 30m between indoor units are possible with unlimited linear or radial-design main piping branches. Up to 64 indoor units are connectable.

Another new Set Free model, the high efficiency FSXNHE, is available in 5hp to 36hp. It has the highest published ESEER figures of any manufacturer across all models from 8hp to 36hp. It is said to be the only 5hp and 6hp high performance 3-pipe VRF model currently on the market. Where even higher efficiency values are required, Hitachi’s special high performance models FSXN1E-P and FSXNHE-P can be specified.
