Description
The Coldflow CFF072V-LF-A is a 6-ton vertical water source heat pump from Coldflow's CFF series, built in Miami, Florida. It is a self-contained water-to-air unit that heats and cools by exchanging heat with a water loop, a well (ground water) or a closed ground loop, so it works on boiler/tower loop systems as well as geothermal installations. This model has a left-hand return, runs on 208/230V single-phase, 60 Hz power and uses low-GWP R-454B refrigerant.
Coldflow builds the CFF series for long service life in demanding environments: a stainless steel cabinet and insulated stainless steel drain pan, a coaxial cupronickel water-to-refrigerant heat exchanger, and a high-efficiency scroll compressor with internal thermal overload protection. It is a strong fit for commercial buildings, multifamily mechanical rooms, schools, offices and light industrial spaces where you want quiet, efficient zone comfort without an outdoor condensing unit.
Key Features
- Stainless steel construction: Stainless steel cabinet and insulated stainless steel drain pan resist corrosion in mechanical rooms, closets and other humid spaces.
- Cupronickel coaxial heat exchanger: Coaxial cupronickel water coil with a steel jacket handles open-loop well water and closed loops alike.
- Scroll compressor: High-efficiency scroll compressor with internal thermal overload protection, mounted on rubber isolators to cut vibration and noise.
- ECM blower motor: Five-speed constant-torque ECM motor with permanently lubricated bearings and a galvanized centrifugal blower wheel.
- Built-in protection: High- and low-pressure switches with a solid-state lockout relay protect the compressor during adverse operating conditions.
- Reliable refrigerant circuit: TXV metering, filter drier(s) and a pilot-operated reversing valve with a replaceable encapsulated coil.
- Quiet operation: Closed-cell insulation lines the cabinet to reduce sound transmission into occupied spaces.
- Service-friendly: Pre-colored thermostat wires and easy-disconnect brackets simplify motor and blower wheel removal.
- Humidity control: Paired with a thermostat that has humidity control, the fan runs at a lower speed to pull more moisture from the air.
- Low-GWP refrigerant: Factory charged with R-454B, the A2L replacement for R-410A.

Benefits
- Lower operating cost: Moving heat to and from water is more efficient than rejecting it to outdoor air, especially on geothermal and well-water systems.
- No outdoor unit: The complete system installs indoors, keeping equipment out of the weather and off the roof or yard.
- Year-round comfort: One unit provides both cooling and heating, with a reversing valve to switch modes.
- Built to last: Stainless steel and cupronickel construction stand up to coastal and high-humidity locations.
Compatibility & Installation
- Applications: Water loop (boiler/cooling tower), open-loop ground water and closed-loop geothermal systems. Use antifreeze on closed loops that can see low entering fluid temperatures.
- Cabinet & return: Vertical cabinet with a left-hand return. Vertical units suit closets and mechanical rooms with ducted supply above the unit. Confirm the return side against your duct and service access layout before ordering.
- Electrical: Requires 208/230V single-phase, 60 Hz service. Size wiring and overcurrent protection to the unit nameplate and local code.
- Water flow: Provide the rated water flow for the unit and install shutoff valves, a strainer and flexible hose kits to simplify service.
- Professional installation: Install by a licensed HVAC professional. R-454B is an A2L refrigerant, so follow current installation codes and the manufacturer's instructions.
Frequently Asked Questions
Can this unit be used for geothermal?
Yes. The CFF series is rated for water loop, ground water and ground loop applications, and the cupronickel coil is suited to open-loop well water.
What does "Left Hand Return" mean?
Facing the front (service panel) of the unit, the return air enters from the left side. Pick the return side that matches your duct layout.
What voltage is this model?
The "-A" at the end of the model number means 208/230V single-phase, 60 Hz. This model is also available in other electrical configurations; search for the same model with a different last letter (A = 208/230V 1ph, C = 208/230V 3ph, D = 460V 3ph).
Where is it made?
Coldflow builds its water source heat pumps in Miami, Florida, USA.
