High Efficiency Circulator
By HPAC MagazineHydronics
Grundfos ALPHA2 high efficiency circulators with ECM motor design offer simple push button control to program in one of three constant speed, three-constant pressure, or AUTOADAPT control modes. The current operating mode is always visible on the circulator’s LED display. The large LED display shows the current energy consumption in Watts and estimated flow in gallons per minute. The circulator is complete with an integrated check-valve, foam insulation jacket, and nut captures for flanges. It comes in both cast iron and stainless steel models. In blocked rotor conditions it will continuously attempt to restart.
