Product Details
The EC Model, provides the best combination of performance, comfort, and one-of-a-kind features that satisfy the high demands of any commercial building.
Bosch EC
The EC Model water-to-air heat pump provides one of the best combinations of performance and efficiency available. Safety devices are built into each unit to provide the maximum system protection possible.
Quiet Comfort
- Cabinet – All panels are insulated with ½” thick, 1.5 lb./cu. ft. dual-density fibreglass insulation for both thermal insulation and noise reduction. For vibration isolation, all compressors are mounted on rubber grommets. Vertical cabinets have an insulated divider panel between the blower compartment and the compressor section to minimize the transmission of compressor noise and to permit operational service testing without air bypass
- Closed-cell Foam Insulation (option) – Helps to provide cleaner, fibre-free air and reduces sound transmission
- Compressor Blanket (option) – A high-density sound blanket that minimizes the transmission of compressor noise
Service Friendly
- Unit Arrangement – All units are designed to be serviced from the front of the unit. Schrader valves for the high and low-pressure gauges are standard, along with easily accessible electrical box components, allow the diagnosing and servicing of the unit to
become a simple task. Insulated bulkheads in all vertical EC Models separate the compressor section from the blower section, allowing the unit to be serviced easily during operation. Panels are removable to facilitate servicing of the unit. Separate electrical
knockouts in the unit corner post allow for easy routing of high and low voltage lines to the inside of the cabinet of refrigerant hoses quickly and securely
Robust and Durable Construction
- Galvanized Steel Cabinet – Provides strength and corrosion protection
- Cupro-nickel Coaxial Heat Exchanger (option) – Protects against corrosion when water conditions are of low quality
- Heat Pump Scroll compressors – Provides durability & ensures that each unit will provide many years of trustworthy performance
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
- Condensate Overflow Protection – Continuously monitors the drain pan for high condensate water level, and if this exceeds normal operating levels, the compressor operation is interrupted to protect against drain pan overflow
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)
- Dual Capacity – All units are designed with dual refrigeration circuits for staged operation
