Superior by Design
State-of-the-Art
The CGWR Series of Water Cooled Chillers includes models ranging in capacity from 15 to 75 tons to meet a wide range of load conditions. Each model is designed for quiet, reliable, high efficiency operation and built to withstand demanding continuous duty cycles.
At the heart of the NWCR product line are the highly efficient scroll compressor and brazed plate evaporator, and the serviceable shell-and tube condenser.
The integral controller continually optimizes unit operation, undertakes fault avoidance strategy during abnormal operating conditions, and displays operational and diagnostic information at the unit and at a remote location if needed.
Efficiency
CGWR chillers combine high efficiency Scroll Compressors and Brazed Plate evaporators to offer full and part load efficiencies that are unmatched when compared to products utilizing reciprocating compressors. Still higher efficiencies are realized at part load conditions.
Reliability
Since its introduction, Scroll Compressors have proven to be one of the most reliable compressors available. While high reliability is inherent with the scroll technology, digital control technology has proven to increase reliability and minimize downtime through sophisticated operational logic, fault avoidance strategy and the ability to stably control peripherals such as water regulating valves and cooling tower fan and pump VFDs.
The 40 through 70 ton models have dual refrigerant circuits to eliminate 100% capacity loss in the event of a compressor failure.
Construction
All CGWR products are assembled on a rugged steel frame with integral lifting provisions and topcoated with industrial two-part epoxy direct-to-metal paint.
Vessels
All NWCR products have cleanable and serviceable shell-and-tube condensers with enhanced copper tubes for high efficiency. This makes the NWCR products suitable for open loop systems and cooling tower applications.
Control
The powerful controller provides complete chiller control and standard interface to BACnet IP and Modbus BMS controls. LonTalk, BACnet MS/TP or Johnson N2 interface is optional.
Control Panel
All CGWR Control Panels are complete with fused control power transformer, safety and operational control components and digital controller boards. Digital controller display/input screen is located in the front door of control panel.
Warranty
All CGWR products are backed by the Standard One Year Limited Warranty. Optional 5 year compressor warranty is available.
Options
Available factory-installed options for CGWR products include non-fused disconnect, full sound attenuation enclosure and/or sound blankets, phase monitor, integral digitally controlled condenser water regulating valve, LonTalk, BACnet MS/TP, Johnson N2 and ice building control. Ship loose options include flow switch and vibration isolation kit.
