SmartSource™ water source heat pumps are designed using the latest technology to achieve some of the highest efficiency single-stage products in the market today. McQuay is the first manufacturer to offer ECM variable fan motors as a standard option across the whole product line, even in the smallest cabinet sizes, for unmatched performance and comfort in the industry. High EERs that far exceed ASHRAE 90.1 standards make these units perfect for LEED projects and rebate opportunities. All units are available geothermal ready from the factory with many features to easily match your application requirements.

 

HVAC System Type
Water Source Heat Pump

Building Application
Ideal for schools, clinics, office buildings, government offices, senior living facilities and other other projects.

Featuring
High EER’s, up to 22.2 at full load and 29.8 in part load, efficient ECM motors standard across the whole product line with multiple field selectable airflow, exceptionally quiet with published sound ratings as low as 46 dBA, geothermal ready with options such as MERV 8 and MERV 13 filters.

Benefits
The new SmartSource line delivers unmatched energy efficiencies with quiet relability in a flexable vertical or horizontal configuration!

1: ECM Fan Motor: 4 field adjustable fan speeds with 5 operating mode options provide a wide range of airflow selections for quieter operation and lower energy consumption.

2: Copeland K-5 Scroll: or LG Rotary available in a variety of commercial voltages, mounted on a double isolation system for reduced sound and vibration.

3: Refrigerant Circuit: Utilizes R-410A refrigerant with a biflow thermal expansion valve for easy metering and four way solenoid reversing valve.

4: MicroTech III Controls: Easy open-protocol integration with optional LonWorks® or BACnet®.

5: Unit Status LED: Instant visuals on unit operation for easy troubleshooting and advanced diagnostics.



6: 4-Sides Filter Rack with Standard 2” or Optional 4” Filters: Designed for easy filter maintenance. MERV 8 & 13 filter options with gasketed filter rack meet LEED-NC EQc5 applications with leakage rate at less than 4 CFM per square foot of filter area at 0.5”ESP.

7: Stainless Steel Drain Plan: Sloped with lipless drain connection for positive condensate flow, meets ASHRAE 62.1 Section 5.11.

8: Flush Mounted Fittings: Easy one wrench connection, securely fastened to the cabinet corner posts.

9: Blower and Motor Orifice Ring: Easy service removal without having to remove the blower housing or disconnecting the unit from the duct work.

10: Durable Cabinet Construction: Heavy gauge steel with powder coated textured paint, lined with cleanable foilfaced insulation on the airside.

 

Many Factory-Mounted Options and Accessories

 

Four Unique Dehumidification Options:

  • Smart Dehumidification – Uses hot gas reheat, humidistat, 2-stage thermostat & smart air flow management for precise humidity control.
  • Simplified Dehumidification – Uses a 3-stage thermostat to optimize unit capacity and fan speed for maximum latent capacity while decreasing room humidity levels.
  • Humidistat Controlled Dehumidification – Uses a humidistat and 2-stage thermostat to control room humidity levels.
  • Dehumidification Only – Uses a humidistat in cooling only mode.

Waterside Economizer - Reduces compressor energy consumption by using a cold water coil for cooling under unfavorable conditions.

Loop Pumps - Convenient factory mounted pumps with flow and head capabilities for most geothermal applications.

5, 10, 15 & 20 kW Electric Heat - For alternate heat source with controls for primary, supplemental, boilerless or emergency heat. (Available as a field-installed duct heater kit)

Non-Fused Disconnect Option - Convenient Power shut-off and lockout at the unit.

Extended Range Coaxial Heat Exchanger Coil and Piping Insulation - for geothermal application.

Insulation Options - Foil faced, closed cell or 1/2” standard fiberglass options for the air and compressor side of the unit.

Epoxy Coated Coils - For extra corrosion protection to meet ASTM B-11 3000 hour salt spray test.

Deluxe Sound Package - Reduces sound levels for quieter operation.

5-Year Extended Parts Warranty Available
