Greenheck's Vari-Green products are designed for energy-efficiency, controllability and low maintenance. They are an environmentally progressive option when specifying products for your next project.
The Vari-Green motor is a low-cost, easy to control, electronically commutated (EC) motor that uses AC input power and internally coverts it to a DC power supply. This highly reliable, energy efficient, low maintenance motor is capable of an 80% turndown and is changing the way the industry designs, specifies and operates air movement equipment
Greenheck’s Vari-Green® Controls have been developed to maximize the efficiency of ventilation systems in a wide variety of applications when used with the Vari-Green motor. By choosing a Vari-Green control with the Vari-Green motor, compatibility issues are eliminated and installation is simplified. These controls are designed to meet the needs for manual or automated operation in demand controlled ventilation systems.
The Vari-Green® Drive is a factory mounted and wired, pre-programmed variable frequency drive designed for 3-phase applications where a Vari-Green motor isn’t an option. Units are compatible with induction and permanent magnet motors and feature a NEMA 4X enclosure. R3 Filtering technology mitigates harmonics to levels in compliance with IEEE 519 without the use of external reactors.
