NEW GENERATION OF CENTRAL CHILLING EQUIPMENT
(10 – 100 TONS CAPACITY)
NAC Series Air Cooled Multi-Circuit Chillers are used in industrial and commercial applications from central chilling of processes to HVAC. Whaley Chillers have become the number one chilling equipment of choice. In these systems, we incorporate new high efficiency Scroll compressors and stainless steel plate evaporators. The multi-circuit design is used on critical process loads that absolutely cannot be down. WPI will provide complete water system design and plant process survey to determine cooling loads.

Systems are shipped with maximum of 5/20 ton circuits per 100 ton chilling bank. Main internal chiller header allows ease of connecting future loads. This allows your chiller system to grow with your operation and reduces the initial investment. Various configurations are available to fit your space requirements. Multi-circuit chillers can be built with integral or remote pump tanks.
