HIGH HEATING CAPACITY
Industry-first flash injection circuit is equipped, which enables to
keep the equal capacity to the rating even when outside tem-
perature is 5°F[-15°C].
HIGH SPEED HEATING START UP
The performance of heating start up is improved. Compared to
PUZ-A type, Hyper Heating Inverter reduced the time for heat-
ing start up by about half. After starting operation, the airflow
temperature goes up to 105°F[41°C] quickly in 10 minutes. With
industry first shorter and less frequent defrost, defrosting time is
cut down by 15% compared to PUZ-A type and heating operation
can continuosly run for maximum 150 minutes.
WIDE HEATING RANGE
The heating range is expanded to -13°F[-25°C] compared to
PUZ-A type which is up to 10°F[-12°C].
CHARGELESS SYSTEM
PRE-CHARGED REFRIGERANT IS SUPPLIED FOR PIPING LENGTH AT SHIPMENT.
Max.100ft, 30m
The refrigerant circuit with LEV(Linear Expansion Valve) and power receiver always control the optimal refrigerant level
regardless of the length (max.: 100ft [30m] and mim.: 16ft [5m]) 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.
