The EcoFit Water-Source Horizontal Heat Pumps are designed to address the unique needs of the New Construction market. EcoFit Water-Source Heat Pumps feature a wide array of selectable options to allow design engineers and owners to optimize the equipment required to address unique building requirements and provide excellent efficiency.

The ProFit Horizontal Replacement Water-Source Heat Pumps are designed to be a “drop-in” replacement for most existing Water-Source Heat Pumps. 

Capacity:

½ - 12 ½ TONS

SPECIFICATIONS

  • Applications
    • Horizontal configuration water-source heat pumps, from ½ to 12 ½ tons
    • Multiple levels of efficiency


  • Performance
    • Large face area DX coil improves the efficiency of the unit, minimizes air pressure drop, and reduces required fan horsepower. Aluminum microchannel coils on the EcoFit minimize refrigerant charge and overall unit weight. Factory provided return duct flange connection is available.
    • High-efficiency direct drive forward curved supply fans available with Permanent Split Capacitor (PSC) motors or Electronically Commutated Motors (ECM).
  • Quality
    • Replacement-ready size matches with conventional water-source heat pumps.
    • Left or right-hand return
    • Left, right or end discharge
    • Integrated hanging brackets with rubber vibration isolation
    • Floating water connections reduce sound
    • Sloped stainless steel drain pan includes automated TIG and induction welding.
    • Induction brazed copper piping connections
    • Integrated two-inch filter rack - standard!
    • 5-year parts warranty - standard!

  • Standard Features
    • R-410A scroll compressors are included on units 2 tons and larger. R-410A rotary compressors are included on units from ½ through 1 ½ tons. Compressors are isolated from the cabinet for reduced vibration.
    • Coaxial heat exchanger provides reliable operation. Cupronickel heat exchanger option is available for additional corrosion resistance.
    • AAON Pioneer Silver Controller with terminal block for connection to standard heat pump thermostat

  • Options
    • Corrosion-resistant cupronickel coaxial refrigerant-to-water heat exchanger
    • Factory installed non-fused disconnect switch
    • Low sound package reduces unit sound
    • Factory provided return air duct connection
    • ECM fan speed control dehumidification
    • Hot gas reheat dehumidification
    • Waterside economizer with three-way motorized valve
    • Ground/ground water loop insulation for geothermal application

  • Sustainability
    • Sturdy galvanize steel construction with fiberglass insulation
    • 5-year parts warranty - standard!
  • Health/IAQ
