Use of ECM-Driven Large Circulators in HVAC Cooling System Applications

Advances in integrated variable speed drives and controls in ECM driven large wet rotor circulators make them an ideal fit for large residential and small commercial two pipe cooling applications.  This presentation will look at various ways to employ these pumps in primary-secondary and primary-secondary-tertiary pumping systems utilizing combinations of the T, DT, and DP functions of the circulator to effectively and efficiently cool and dehumidify the building.
