Vari-Green Motor Technology Added to Greenheck Axial Rooftop Fans

Greenheck recently incorporated its Vari-Green motor in select models of axial direct drive rooftop fans. This industry-first offering provides all of the controllability of a variable frequency drive in a smaller, low-maintenance package that simplifies installation and reduces field costs.

Greenheck axial direct drive fan models now available with Vari-Green technology include exhaust and supply-hooded rooftop models RE2, RS2, RCE3 and RCS3 in seven sizes ranging from 24 to 60 and exhaust upblast rooftop model RDU in five sizes ranging from 24 to 48. These models are available with Vari-Green single- and three-phase motor options up to 5 horsepower and are ideal for warehouses, distribution centers and manufacturing facilities.

Vari-Green motors feature IE5 ultra-premium motor efficiencies and integrated, pre-programmed drives that eliminate the need to purchase a separate VFD. Additional Vari-Green features include standard onboard internal shaft grounding and onboard motor protections including overheat, locked rotor, stall and overload.
