Aquazone™ Water-Cooled Two-Stage Water Source Heat Pump
50PTH

with Puron® Refrigerant (R-410A)

2 to 6 Tons

The 50PTH indoor water-cooled heat pump unit is designed for horizontal installation with a variety of airflow configurations. These units utilize Puron® refrigerant, modulating scroll technology, and hot gas re-heat to provide a practical and economical approach for comfort conditioning requirements in renovation and new construction applications. The 50PT unit can be used in both traditional and geothermal applications, and is also ideally suited for geothermal projects seeking LEED®1 certification.
