CHARLOTTE, N.C. — Carrier, a part of Carrier Global Corp., has introduced three new water-source heat pump models, the Aquazone 50WC, 50WD, and 50WT, which feature the lower-GWP Puron Advance refrigerant.
The 50WC is available in capacities from 0.5 tons to 6 tons and has a compact design in both vertical and horizontal configurations. The 50WD is available in the same range of capacities and offers a higher efficiency level; the models of 2 tons and greater have two-stage operation. The 50WT offers the highest level of efficiency in the series, and also has two-stage operation in the models of 2 tons and greater.
All 50W-Series models include enhanced serviceability features, a wide variety of factory-installed options, and flexible configurations suitable for boiler tower, geothermal, and hybrid water loop systems, a press release from Carrier said.
“The AquaZone heat pump line was created to offer increased efficiency and configurations to match a wide range of applications,” said Alan Youker, senior product manager at Carrier. “The 50WC is our latest update, providing more options and a smaller footprint and proving once again that Carrier is committed to providing intelligent HVAC solutions to fit the needs of its customers. The 50WD’s and 50WT’s higher efficiency and use of lower-GWP refrigerant makes them ideally suited for LEED certification projects, especially those involving geothermal systems.”
Puron Advance is the commercial name for the refrigerant R-454B, which Carrier has adopted for its light commercial and residential products. Its GWP of 466, according to the Intergovernmental Panel on Climate Change Fourth Assessment Report, is a 75% reduction from that of R-410A.
