Compact, the FHP LV Model is a single-stage water-source heat pump designed for use in retrofit or replacement applications. Available in ½ to 6 tons and in horizontal or vertical (upflow or downflow) configurations, the heat pump exceeds ASHRAE 90.1 efficiency standards and can be used for either water-loop or geothermal applications. Horizontal cabinets come standard with blower systems that can be easily reconfigured from end to straight discharge in a matter of minutes, said the company. The vertical cabinet’s blower assembly can be selected for top or side discharge to meet different ducting configurations. A copper coaxial heat exchanger is a standard feature. When water quality is in question, an optional corrosion-resistant cupronickel coaxial heat exchanger is available to enhance the life of the unit.
