MODULAR CENTRAL CHILLING EQUIPMENT
COMPA-CHILL “NAE SERIES” AIR-COOLED MODULAR CHILLERS
(5 Thru 20 TONS CAPACITY)

NAE Series Modular Air Cooled Chillers are used in industrial and commercial applications from central chilling of processes to HVAC. COMPA-CHILL modular chillers has become a popular choice for replacement and or new installations, Modular chillers incorporate high efficiency tandem Copeland Scroll compressors are available on 12.5-20ton modular chillers. A multi-circuit modular system with multiple units can be totally isolated from each other with refrigeration and water valves. Having this capability offers a higher level of reliability and redundancy on critical installations.

Case history shows most large chillers operate at 20-30% of maximum rated load. With the multiple circuits you can operate smaller modules and save energy and maintenance cost. Controls are straightforward off the shelf and in-house maintenance personnel can service the equipment. WPI will provide complete water system design and plant process survey to determine cooling loads.

Isolated chilling circuits contain:
~ Tandem rotary Scroll Compressors
~ Stainless steel plate evaporators
~ Refrigeration TEV w/ external equalization
~ Refrigeration sight glass and filter dryer
~ Refrigeration service valves and ports
~ Charged and tested prior to shipment
~ Wiring diagrams and manuals
~ 1 year parts and compressor warranty
Electrical:
~ Compressor and fan contactors
~ Compressor overload protection
~ Individual temperature control
~ Manual compressor start
~ Fused 24volt control
