Product Details
Industry-leading single-stage efficiencies, standard features, and a variety of options – providing energy-efficient solutions to accommodate your building requirements.
Bosch EP
The EP Model, water-to-air heat pump offers high efficiency, value-added features and a single-stage compressor (scroll type 1 1/2 – 6 ton sizes). An optional ECM constant airflow (variable speed) fan motor can give you the flexibility, performance and quiet operation needed to meet the expectations of your clients.
Quiet Comfort
- Floating Compressor Base – Reduces vibration and noise transmission from the compressor to the structure
- Closed-cell Foam Insulation (option) – Helps to provide cleaner, fibre-free air and reduces sound transmission
- Compressor Blanket (option) – Offers optimum low sound levels (not available on smaller units with rotary compressor)
Service Friendly
- Blower Inlet Ring – (available in 015-070 only) Allows quick servicing of blower fan motor without disassembly of the blower housing
- Insulated Divider – 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
- Evaporator Coil Protection with DuoGuard™ (option) – Tin electro-plated copper tubing with high-tech polymer-coated aluminium fins that aid in protecting the evaporator coil from most forms of corrosive elements in the air stream
- Stainless Steel Drain Pan – Resists cracking & 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
- 40A non-fused disconnect (option) – Allows shut off of unit without lockout of the main panel (N/A with electric heat)
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 unit to protect it
Quality Design & Efficiency
- Boilerless Control (option) – Disables the compressor and/or activates electric heater should the water temperature drop below the adjustable set point
- Water Side Economizer (option) – Provides free-cooling without the use of mechanical cooling (compressors)
- Extended Range (option) – Accommodates geothermal closed-loop applications when Entering Fluid
- Temperatures are anticipated below 60 °F
- TXV – Bi-flow thermal expansion valve for optimum performance over a wide range of heating and cooling conditions
- Heat Recovery Package (option for 024-070 in -1 or -3 voltage only) – Provides domestic water heating during the air conditioning or heating mode to supplement your building’s potable water heating needs assisting any electric domestic water heating storage tank
