The VST Series provides tremendous power savings at part load points, which save you thousands of dollars in energy costs each year. The compressor matches the supply of compressed air, at the specified target pressure, to your system’s specific demand while minimizing the power required to compress the air. Typical compressors either modulate the inlet valve and/or vary the displacement of the first stage to control the capacity of the package. These methods do not offer the power savings of a variable speed control matched to the most efficient compressors nor are they able to achieve the wide operating range of the VST Series products.
Savings When Air is Not Needed
When air is not needed, the VST Series compressors stop running and do not vent to atmosphere; eliminating any waste of compressed air in the reservoir. The “soft” starting capability of the AirSmart™ controller allows the motor to start against a pressurized system at any time and will do so as often as required by the system. Our attention to this energy saving detail is just another example of the energy savings delivered by Gardner Denver.
