Central Plant Optimization

Too often central plants are controlled to do only one thing – maintain a constant water temperature.

This simple task frequently misses the opportunity to maximize the operational performance of the plant. As experts in chillers, boilers, controls and system performance, MacDonald-Miller can operate your central plant at maximum efficiency 100% of the time. We do so by combining our systems knowledge with Iconics continuous commissioning analytics and visualization reporting software.
