CHARGELESS SYSTEM
PRE-CHARGED REFRIGERANT IS SUPPLIED FOR PIPING LENGTH AT SHIPMENT
Max. 10m (PUHZ-SW40/SW50)
The refrigerant circuit with LEV (Linear Expansion Valve) and power receiver always control the optimal refrigerant level
regardless of the length (10 m max. and 5 m min.) of piping. The additional refrigerant charging work during installation
often causes problems. It is completely eliminated by chargeless system. This unique system improves the quality and reli-
ability of the work done. It also helps to speed up the installation time.
