Screw compressors feature VSD technology

Screw compressors feature VSD technology

Starting mid-2016, more of Atlas Copco’s GA oil-injected rotary screw compressors will be available with energy-saving variable speed drive plus (VSD+) technology.

Atlas Copco has been phasing in this new technology. Until now, only GA 7-37 compressors came with VSD+. But that will change soon. Starting in mid-June, all pack and full feature versions of the GA 37, GA 45, GA 55 and GA 75 kW compressors will also be available worldwide with VSD+ technology.

A VSD compressor automatically adjusts its motor and element speed to the air demand. A traditional fixed speed compressor is either on or off. A VSD only runs at the required speed, considerably cutting energy use and costs.

An Atlas Copco GA VSD+ compressor features an iPM (Permanent Magnet) motor, a new compression element and a sentinel valve. These new technologies allow it to deliver more energy savings than the first generation of VSD compressors, says the company. Free Air Delivery (FAD) and Specific Energy Requirement (SER) are both improved by up to 9%, says Atlas. This means customers get up to 9% more air while using up to 9% less energy with the GA VSD+ compared to the GA VSD.
