- Variable speed air compressor
A Variable Speed Drive (VSD) Air Compressor [ [http://www.quincycompressor.com/qgv.html Variable Speed Drive Compressor] ] is an air compressor that takes advantage of
Variable Speed Drivetechnology. This type of compressor uses a special drive to control the speed (RPM) of the unit, which in turn saves energy compared to a fixed speed equivalent.
The most common form of
VSDtechnology in the Air Compressor Industry is a Variable Frequency Drive, which converts the incoming ACpower to DC & then back to a quasi-sinusoidal AC power using an inverter switching circuit. The variable-frequency drivearticle provides additional information on electronic speed controls used with various types of AC motors.
The benefits of this technology included reducing power cost, reducing power surges (from starting AC motors), and delivering a more constant pressure. The down side of this technology is the heavy expense associated with the drive, and the sensitivity of these drives - specifically to heat and moisture.
Typically, a fifth of a factory's electricity bill is attributed to the production of compressed air. The majority of modern factories are heavily involved in cutting costs, and energy awareness should be a key concern. For example, 10-12% of all power generated in the UK is dedicated to the production of compressed air, and a portion of this power is wasted energy.
Large electrical cost savings be achieved by installing a variable speed drive compressor in place of an existing rotary screw or piston machine. Because of this, many governments, including the US & UK, are pushing the industries to move towards this technology in hopes of reducing wasted energy. Governments offers various incentives, such as tax rebates or interest free loans, to cover the upgrades.
A professional air audit is the best way to see if a VFD compressor is right for your application.
