Greenheck announced that the DGX and MSX air distribution models can now be configured with full supply fan curved backwards and direct drive. Both models offer an operating range with a capacity of 800 - 25,000 cubic feet per minute and external static pressure of up to 4 inches in gw.
In addition, the DGX-P and P-MSX models offer additional design solutions when an application requires higher external static pressures caused by a wide network of ducts or higher efficiency filtration.
The factory-made variable frequency controller provides an inherent smooth start for the supply fan, while the absence of belts and pulleys also reduces maintenance and simplifies air balance in the field.
Available heating options include, direct with gas, electric heating, hot water and steam coils; while cooling options include direct expansion split, cooled water, and evaporative cooling. The new full-supply fan curved backwards can lead to lower use of motor horsepower and power, compared to other fan options.
