This system was a retrofit to a existing MCC and a new control panel to provide chilled water to several injection molding machines. The previous control’s were out of date and no longer reliable. We designed, built, programmed and commissioned this new system. Chilled water pumps, recirculation pumps, chilled water tower pump down and chiller cooling fans were all incorporated into a fully automatic on demand system.
The system ran with input from the demand of machines running, analog sensors monitoring temperature, and flow to maintain adequate cooling of the injections machines. Manual interface could be achieved to bypass certain areas for maintenance and high demand areas.
