Page 5: What Is The Chilled Water System Optimizer
What is the Chilled Water System Optimizer? The Chilled Water System Optimizer (Part# OPN-OPT-OL) provides precise chilled water and condenser water setpoint optimization by carefully balancing the energy use of both the chilled water plant equipment and the chilled water consumers. This results in an overall reduction in energy use and electrical demand. -
