Direct drive supply fan for make-up air
DGX and MSX can be configured with a direct drive, backward-curved plenum supply fan.
Greenheck's air models DGX and MSX can be configured with a direct drive, backward-curved plenum supply fan. Both models offer an operating range capable of 800 to 25,000 cfm and external static pressure up to 4 in. wg. The DGX-P and MSX-P offer additional design solutions when an application requires higher external static pressures. The factory-mounted variable frequency drive provides an inherent soft-start for the supply fan. Available heating options include direct gas-fired, electric heat, hot water and steam coils; cooling options include split direct expansion, chilled water, and evaporative cooling. The new backward-curved plenum supply fan offers low motor horsepower and energy usage.
