CHARGELESS SYSTEM PRE-CHARGED REFRIGERANT IS SUPPLIED FOR UP TO 30m PIPING LENGTH AT SHIPMENT.

The unique refrigerant circuit and a large accumulator always control the optimal refrigerant level regardless of the length (50m max. and 5m min.) of piping. The additional refrigerant charging work during installation often causes problems. Therefore, it is completely eliminated. This unique system improves the quality and reliability of the work done. It also helps to speed up the installation work.
