Project story
The challenge
The existing Trane plant operated at approximately COP 4.5, with no VFD on the pumps or cooling towers, and reported annual electricity use of 2,112,000 kWh.
Our solution
APC selected a SMARDT oil-free chiller and CPECS control of the chilled-water pumps, condenser-water pumps and cooling towers. The Cooling Division profile records a 450 RT installation.
The result
The reference reports approximately 67,830 kWh per month of plant electricity consumption over the first four months. The original proposal expected 30% savings; the monthly figure is consumption, not energy saved.
