October 14, 2020

Greenheck has added three-phase motors to its line of energy efficient Vari-Green electronically commutated (EC) motors. The new three-phase motors accept 208-230V and 460V power supply and are available in sizes ranging from 1 to 10 hp. Typical turndown is factory-set at 75% and speed can be controlled via an onboard dial or a 0-10 VDC control signal. Low maintenance Vari-Green motors run quieter and cooler and offer higher efficiencies compared to standard motors; the three-phase Vari-Green motor operates at IE5 efficiency levels. The three-phase motor is compatible with all Vari-Green controls and other controls such as a building automation system and has an auxiliary contact for motor status or damper actuation. The three-phase Vari-Green motor can be ordered with select sizes of Greenheck models SQ inline fans, AER axial fans and models G and CUE power roof ventilators.

Features:

  •    –   Accept 208-230V and 460V power supply
