The PWFY Hydronic Heat Exchanger is available in two configurations, the HEX (-AU) and the Booster (-BU). Each provides unique solutions to incorporate into an existing VRF system for an efficient means to heat and cool water. The PWFY Hydronic Heat Exchanger is a closed-circuit water heater that works with the Y-Series and R2-Series outdoor units.

HEX unit (-AU)

• Heats water to 115° F
• Hydronic heat exchanger transfers energy from refrigerant to water
• Can be used to recover waste heat from cooling operation to water when combined with R2 or WR2 systems, resulting in large energy savings
• Applications include radiant heating, snow melt, reheating air, preheating hot water and more
• Cools water to 41°
• Can be used for cooling outside air, cooling pool water, misting stations, process cooling, drinking water and more

Booster unit (-BU)

• Heats water to 160° F
• Hydronic heat exchanger transfers energy from refrigerant to water
• Can be used to recover waste heat from cooling operation to water when combined with R2 or WR2 systems, resulting in large energy savings
• Applications include radiant heating, hot water preheating, melting snow, reheating air, warming pools, and more
• Unit is not suitable for direct potable water flow
• Includes R134A compressor circuit for boosting water temperature
• Can only be used with R2 and WR2 systems
