The new, extended-capacity Duplex CenTraVac chiller can produce up to 3,950 tons of cooling. The chillers, nominally sized for 3,000 and 3,500 tons, come standard with the Tracer™ chiller controller. The company states that the chiller is highly efficient because of its direct-drive motor, multistage compressor design, and use of low-pressure R-123. The CenTraVac has received the U.S. Environmental Protection Agency’s Climate Protection Award.
