The Carrier Aquazone 50WC water source heat pumps utilize Puron Advance low GWP refrigerant (R-454B), with a GWP of 465, ensuring compliance with U.S. EPA (Environmen¬tal Protection Agency) and other regula¬tory agency limits of 700. They offer a compact, cost optimized design in both a vertical and horizontal pack-aged configuration. Enhanced serviceability features, a wide variety of factory-installed options, and flexible configurations suitable for boiler tower, geothermal, and hybrid water loop systems. Optional integrated Carrier TruVu controls allowing for advanced equipment control and monitoring and seamless integration to the i-Vu building automation system.

Standard Features:

• Compact Aquazone units include a rotary compressor in sizes 007-030 and a scroll compressor in size 024-070 units.
• Compressors are mounted on a double isolated system (i.e., from the cab¬inet) that maximizes vibration isolation and minimizes transmission to the unit structure
• Permanent split capacitor motors (PSC)
• All 50WC units have a unique floating basepan; the compressor is mounted on a heavy steel plate which rests on a high density rubber pad on the base of the unit. In addition, compressors are mounted on rubber grommets. This double isolation is standard in all 50WC units preventing vibration and noise transmission from the compres¬sor to the unit structure, resulting in exceptionally quiet operation.
• Thermal expansion valve — Units are equipped with a thermostatic expansion valve (TXV) metering device to ensure reliable operation across a wide range of entering air and water temperatures
• Reversing valve (4-way valve) — Units are equipped with a refrigerant reversing valve. This valve’s operation is specifically controlled to switch modes, ensuring heightened reliability in functionality.
• Pressure ports — All units are provided with high and low pressure ports integral to the refrigeration circuit for ease service.
• Filter drier — Standard on units with scroll compressor 2 tons and up, the refrigerant circuit filter drier enhances system performance by efficiently filtering and removing contaminants for improved longevity and efficiency
• All units come standard with a copper tube, aluminum-fin air coil. These air coils employ lanced fin and rifled tub¬ing for maximum heat transfer. Large face areas result in lower face velocity reducing sound while ensuring high latent heat removal for maximum dehumidification in cooling mode. Additional air coil coating protection option is available for units.
• 50WC units are offered with a Copper coaxial (tube-in-tube) refrigerant to water heat exchanger. Optional Cupronickel coaxial heat exchanger is available for higher corrosion protec¬tion. Additionally, heat exchanger is insulated to prevent condensation, and therefore potential dripping problems, in applications where the entering water temperature is less than 50°F
• Design flexibility
• Simple maintenance and serviceability
• Anti-short cycle timer
• High and low pressure refrigerant protection
• Service Test mode with diagnostic LED

Cabinet Features:

• Heavy gage galvanized sheet metal cabinet construction enablespart standardization (i.e., minimal number of parts) and modular design
• Cabinet interior surfaces are lined with 1/2 in. thick, 11/2 lb acoustic type insulation with a clear acoustic coating
• Sheet metal surfaces are treated for maximum corrosion protection to provide resilience for long term vitality
• Compact cabinet dimensions fit tight space limitations in both horizontal and vertical configurations
• Hanging Brackets
