Building owners and facilities managers are often looking for a way to improve the performance of their internal systems, reduce time spent on maintenance, and reduce costs—especially when it comes to delivering hot water.
Recent advancements in motor controls have had huge impacts on the circulator pump market. Specifically, circulator pumps with what are known as Electronically Commutated Motors, or ECMs, trigger an intelligent speed control system that provides substantial energy savings. This is because speed-controlled pumps automatically adjust their output to changing demand...
The Hydraulic Institute (HI)—in collaboration with NEEA, pump manufacturers, U.S. Department of Energy, and utilities—developed the HI Energy Rating (ER) Label. The label is designed to clearly indicate the power savings available from pump upgrades and changes. By using the label, manufacturers and distributors can quickly compare the relative power...
Many large buildings and campuses have HVAC water-distribution systems, also called hydronic systems. Water is heated or cooled in a central plant, then pumped to air handlers, where ventilation air is conditioned as needed.
