Small Circulator Pumps with Automated Control

Small circulator pumps propel fluid through closed-loop heating and cooling systems to regulate air or water temperature. Researchers evaluated the technology in two common applications at the Denver Federal Center, a domestic hot water (DHW) recirculation system and an air handler unit (AHU). They found that the pumps reduced energy use 26% to 96%, with payback of less than 6 years. View full-size infographic. [PDF - 426 KB]
