Enhanced
The ES 2-stage, water-to-air heat pumps offer high efficiency, value added features and dual capacity with standard features like a two speed scroll compressor and a ECM constant airflow fan motor, giving you the flexibility, performance and quiet operation needed to exceed the expectations of your clients.
Quiet Operation
- Floating Compressor Base - Reduces vibration and noise transmission from the compressor to the structure
- Closed-cell Foam Insulation (option) - Helps to provide cleaner, fiber-free air and reduces sound transmission
- Compressor Blanket (option) - Offers optimum low sound levels
Service Friendly
- Blower Inlet Ring - Allows quick servicing of blower fan motor without disassembly of blower housing
- Insulated Bulkheads - Separates the compressor and blower sections, allowing the unit to be serviced easily during operation
- Schrader Charging Valves - Facilitates service diagnosis by allowing the connection of refrigerant hoses quickly and securely
Robust and Durable Construction
- Galvanized Steel Cabinet - Provides strength and corrosion protection against the elements
- Stainless Steel Drain Pan - Resists cracking and corrosion which provides long-lasting reliability for condensate collection
- Cupro-nickel Coaxial Heat Exchanger (option) - Protects against corrosion when water conditions are of low quality
Safety
- Flow Proving Switch (option) - Prevents the operation of the compressor should the water supply fail
- Unit Protection Module (UPM) - Monitors the unit operation and safety controls that protect the unit
- Dual Refrigerant Freeze Sensors - Monitors if refrigerant temperatures reach freeze limits and disables the compressor to protect it and prevent nuisance trips
Quality Design & Efficiency
- LEED® Friendly Design - Helps qualify for the most credits possible with a water source HVAC system
- Boilerless Control (option) - Disables the compressor and/or activates electric heater should the water temperature drop below set point while in the heating mode
- Water Side Economizer (option) - Provides free-cooling without the use of mechanical cooling (compressors)
- Extended Range - Accommodates a wider range in temperature swings commonly found in geothermal projects
- Heat Recovery Package (option) - Provides domestic hot water at 120°F to supplement your needs while the unit is in operation
