The RB Series raises the bar for boiler/tower applications by providing fl exibility and effi ciency into a compact cabinet at a competitive price. A
compact cabinet is important when choosing a replacement heat pump. Many water source heat pumps of the 1980-90’s were relatively low
effi ciency models with a small footprint. Once they are installed in a building and piping and ductwork is piped around the unit replacement with
a larger footprint is nearly impossible. The RB Series combines the high effi ciency of 21
st
century product in a footprint that matches a 1980 heat
pump for easy replacement. The chart below shows a comparison of a typical 1980 legacy wshp and current competitor data versus the RB
Series.
This full range product offers all the standard commercial voltages using high effi ciency rotary and scroll compressors along with either
3-speed permanent split-capacitor (PSC), 5-speed ECM, or variable speed ECM blower motors.
RB Series Highlights
• High effi ciency performance
- With PSC Blower Motor Up to 14.0 EER and 4.7 COP (ISO/AHRI 13256-1-WLHP)
- With Variable Speed ECM Blower Motor Up to 14.7 EER and 4.9 COP (ISO/AHRI 13256-1-WLHP)
- With 5-Speed ECM Blower Motor Up to 14.7 EER and 4.9 COP (ISO/AHRI 13256-1-WLHP)
• Unrivaled cabinet footprint that can fi t most application requirements
- A four ton horizontal unit less than four feet long means the smallest horizontal cabinets in the industry!
• All-Aluminum rifl ed tube-and-fi n air coils are not susceptible to formicary corrosion.
• Dedicated 460V 5-Speed ECM does not require use of a neutral!
• Aurora Base microprocessor control capable of operating 5-speed ECM or variable speed ECM with internally mounted 2-way valve
• Flexible factory installed options
- Corrosion-proof composite or stainless steel drain pan; including internally mounted secondary drain connection option
- Copper or cupronickel heat exchanger and optional low temperature insulation
- Filter options: standard 1 in. MERV 4 or option 2 in. MERV 13 with either fi lter rails or option deluxe four sided fi lter rack that
is fi eld switchable between 1 in. and 2 in.
- Aurora Base Control FEC 2611 with N2, LonWorks, or BACnet cards
- Factory mounted internal water valve and/or fl ow regulator for variable speed pumping systems saves on installation costs
- Other options: Sound Kit, Coated Air Coil, Phase Guard, Internally Mounted Non-fused Power Disconnect
