The CLIMATEMASTER C63C0003N05 is a copper coaxial coil designed to transfer heat between refrigerant and water within geothermal and water-source heat pump systems. The coaxial construction routes refrigerant through one channel and water through a separate channel simultaneously, enabling efficient thermal exchange without allowing the two media to contact each other. This design supports the refrigerant circuit and the water loop as an integrated heat exchanger assembly. Licensed HVAC technicians install this coil as a core component of the heat exchange section in geothermal and water-source heat pump units.
This coil is intended for use in geothermal and water-source heat pump HVAC systems where reliable refrigerant-to-water heat transfer is required. Typical applications include residential and light commercial installations using closed-loop or open-loop geothermal systems. The copper construction supports thermal conductivity demands common in these system types. It connects directly to the refrigerant circuit and the water loop within the heat exchanger section of the unit.
Designed as an OEM-style replacement coaxial heat exchanger coil for geothermal and water-source heat pump systems.
Installation should be performed by a licensed HVAC technician with experience in geothermal or water-source heat pump systems. De-energize the unit and isolate the water loop before beginning any coil removal or installation work. Refrigerant circuit work must comply with EPA Section 608 handling requirements. Verify all fittings and connections to both the refrigerant circuit and water loop are leak-free before returning the system to service.
