Oil-Sealed rotary screw pumps with variable speed drive (VSD) technology
Thanks to the variable speed and the set point control, GHS VSD+ is delivering the desired flow without excess. There is no waste of energy. The state-of-the-art screw technology directly driven with an IE3 Premium Efficiency Motor contributes as well to a low power consumption.
The hot and cool zones isolate the heat producing high temperature components from electronic components, which warranty the great performances of the pump, avoiding condensation. This assures a perfect cooling and a long life to the electronic components. Besides, the screw element life is significantly longer than vane life which allows to increase significantly the time between maintenances.
With an innovative and patented design of oil retention that retains oil at <3 mg/m³, even under the greatest load, gives you an optimal exhausted air quality. Besides, thanks to the silent components, canopy and variable speed drive, the noise level is reduced by two, comparing to traditional technologies.
GHS VSD+ is a plug-and-play solution, including an Elektronikon controller, cubicle, and canopy. Besides the installation is in a single, neat enclosure with a small footprint (equivalent to the size of a standard pallet for GHS 350-900VSD+).
