50PSH AQUAZONE™

Indoor, Water-Cooled
Single-Stage Water Source Heat Pump
with Puron® Refrigerant (R-410A)

½ to 6 nominal Tons

50PSH - Horizontal
50PSV - Vertical
50PSH Icon

The 50PS indoor, water-cooled heat pump unit is designed for vertical and horizontal installation with a variety of airflow configurations. Units utilize Puron® refrigerant and Hot Gas Reheat to provide a practical and economical approach for comfort conditioning requirements in renovation and new construction applications. The 50PS unit can be used in both traditional and geothermal applications, and is also ideally suited for geothermal projects seeking LEED® certification.
