Retrofit magazine recently recognized Greenheck model ECV-40 as one of the publication’s Top 25 Products of 2020. The eighth annual Top 25 Products, which appears in Retrofit’s January/February 2021 issue, celebrates the products that received the most reader inquiries from the magazine’s November/December 2019 through September/October 2020
The ECV-40’s design features a dual-fan arrangement consisting of direct drive mixed-flow plenum fans with variable frequency drives (VFDs) replacing the forward-curved fan typically found in energy core ventilators. The mixed flow fan, a hybrid between an axial propeller and centrifugal fan, reduces brake horsepower requirements by up to 50%. The VFDs facilitate ease of balancing at start-up. Sound power levels are reduced, and no belts make maintenance easy.
