Mitsubishi Heavy Industries Air Conditioning Europe (MHIAE) has expanded its KXZ3 2-pipe VRF series with the launch of seven new medium and large-capacity models, now available in sizes up to 67kW and all operating on R32 refrigerant.
With the option to combine units to meet system capacities of up to 201kW, the manufacturer believes the extended line-up strengthens its offering for large commercial buildings seeking high-efficiency, low-GWP solutions.
To maximise efficiency, all systems incorporate the patented Variable Temperature and Capacity Control (VTCC+) technology (registered in Japan), which automatically adjusts refrigerant pressure in line with indoor load conditions. This ensures highly accurate temperature control while delivering notable energy savings, and without compromising noise levels; KXZ3 offers four 'silent' modes reducing sound pressure levels to 47dB(A) .
The latest models introduce a newly developed scroll compressor featuring liquid injection, an improved oil-return structure, and an optimised discharge-port design, all of which contribute to smoother operation and increased durability. A new high-density heat exchanger further improves performance, allowing for a smaller unit footprint and a reduced refrigerant charge, vital to mitigate the need of safety measures and reduce overall project cost.
In addition, refinements to airflow management increase seasonal efficiency and provide higher external static pressure, supporting more complex ducted installations across a variety of commercial environments.
