PWFY OVERVIEW (Hydronic Heat Exchanger)
Hot and cold water,
quickly and efficiently.
PWFY: Hydronic Heat Exchanger
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.
PWFY-P72NMU-E-AU
(Hex)
Available sizes: 36,000 & 72,000 Btu/h
PWFY-P36NMU-E-BU
(Booster)
The PWFY Hydronic Heat Exchanger is a closed–circuit water
heater that works with the Y-Series and R2-Series outdoor
units. The system can produce cool water to 50˚ F and heat
water up to 115˚ F and is available in capacities of 36,000
and 72,000 Btu/h. The Booster unit can produce hot water
up to 160˚ F and is available in a capacity of 36,000 Btuh.
HEX unit (-AU)
(Compatible with the Y- and R2-Series)
• 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 the R2
system, resulting in large energy savings
- Applications include radiant heating, snow melt,
reheating air, preheating hot water and more
• Cools water to 50° F
- Can be used for cooling outside air, cooling pool
water, misting stations, process cooling, drinking water
and more
• Unit is not suitable for direct potable water flow
• Connectable only with CITY MULTI modular R2, Y, WR2
and WY systems
• Y-strainer included
• Uses PAR-W21MAA to control operation
Booster unit (-BU)
(Compatible with R2-Series)
• Heats water to 160° F
• Hydronic heat exchanger transfers energy from
refrigerant to water
• Can be used to transfer waste heat from cooling
operation to water, 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
• Connectable only with modular CITY MULTI R2 and
WR2 systems
• Y-strainer included
• Uses PAR-W21MAA to control operation
The Hydronic Heat Exchanger offers the flexibility to meet the
needs of almost any commercial application. The ability of
the HEX to heat water up to 115 o F makes it ideal for in–floor
radiant heating, snow melt, domestic hot water preheating,
and hot water preheating. The ability of the Booster to heat
water up to 160 o F makes it ideal for hot water heating for
hydronic coils, perimeter radiant heat, and commercial
kitchen domestic hot water. Both systems create hot water
efficiently either through the use of the INVERTER drive
compressor or through reclaimation of waste heat from the
cooling cycle.
