Focus on: Fujitsu J-IIS Mini VRF (2-Pipe)

Thursday, July 16th, 2015

It’s easy for this little diamond to go under the radar,  given it has a height of less than 1M.  The Fujitsu Air Conditioning J-IIS Mini VRF is becoming a very popular option for applications where space is restricted or the height of the condensing unit it paramount.

Fujitsu Air Conditioning J-IIS Outdoor

The single fan VRF can connect up to 8 fan coil units with up to 130% connected capacity and has a quiet operation of as low as 51dB(A) (4HP model).  Despite it’s small size, it certainly isn’t small in operation.  Comprising of full DC inverter control, a DC twin rotary compressor, a three row large heat exchanger and DC fan motor.

Not forgetting the engineer either, the outdoor has been designed for easy maintenance.  It has a 7 segment LED showing operation status, addressing & pressures hosted with a removable PCB panel for ease of access.

There is a full range of easy-to-use controllers available, from wireless remote controls to a PC-based control software. The installation can also be linked to a building management system. The touch panel LCD wired controller has a large clear screen for ease of use and allows service engineers to interrogate indoor and outdoor units to diagnose the system.

The Fujitsu Air Conditioning J-IIS Mini VRF is available from Cool Designs Ltd.
