FEATURES

HIGH HEATING CAPACITY
Industry-first flash injection circuit is equipped, which enables to
keep the equal capacity with the rating even when outside tem-
perature is -15 .
HIGH SPEED HEATING START UP
The performance of heating start up is improved. Compared to
RP type, Zubadan reduced the time for heating start up by about
half. After starting operation, the airflow temperature goes up to
45 quickly in 10 minutes. With industry-first shorter and less
frequent defrost, defrosting time is cut down by 15% compared
to RP type and heating operation can continuously run for maxi-
mum 150 minutes.
WIDE HEATING RANGE
The heating range is expanded to -25
which is up to -20 .
CHARGELESS SYSTEM
PRE-CHARGED REFRIGERANT IS SUPPLIED FOR PIPING LENGTH AT SHIPMENT.
Max.30m(PUHZ-HRP71/100/125)
The refrigerant circuit with LEV(Linear Expansion Valve) and power receiver always control the optimal refrigerant level
regardless of the length (30m max. and 5m min.) of piping. The additional refrigerant charging work during installation often
causes problems. It is completely eliminated by chargelss system. This unique system improves the quality and reliability of
the work done. It also helps to speed up the installation time.
REFRIGERANT LEAKAGE DETECTION FUNCTION
PUHZ-HRP·HA can detect refrigerant leakage which may happen during a long period of use.
