Compact climate control for large spaces

Hitachi exclusive : sideflow heat recovery

Supports up to 39 indoor units, individually controlled with simultaneous heating and cooling to achieve complete comfort for all occupants across the whole site. Compatible with a wide range of single and multi changeover boxes for the ultimate onsite installation flexibilty.

Easy Installation

Lightweight and compact design — the maximum depth is just 390mm — make transport and installation easy. Footprint of heat recovery units up to -43% smaller than market equivalents. Quiet operation provides alternative installation options, such as balconies and on the side of buildings where roof space is limited.

Less refrigerant makes SET FREE Mini ideal for hotels where guests can control their own comfort without there being a need for costly leak detection systems.

Energy Efficiency

Heat recovery systems work by transferring excess energy from one zone to another. This exclusive feature for 8-12 hp sideflow units allows SET FREE mini to reach a SEER of 8.31 and a SCOP of 5.62 for a greener climate control solution and lower running costs.


'Smooth Drive' control is a newly developed refrigerant cycle control technology that reduces power consumption by -39% at low loads and ensures a constant room tempeature and keeps the compressor safe from shocks for longer life and more reliability.

GENTLECOOL: Hitachi exclusive function

Cold drafts are a thing of the past as Hitachi's exclusive climate control solution allows users to individually control the air off temperature of each and every fan coil just by the use of the local controller. This can therefore be changed whenever the occupants desire unlike other solutions where the air off tempearture is fixed for every user regardless of their individual comfort needs.
