Atlas Copco Compressors Australia announces a new range of rotary screw vacuum pumps featuring variable speed drive (VSD) to increase energy savings and productivity for customers across diverse industries.

Representing a new innovation in vacuum technology, Atlas Copco’s GHS 350-900 VSD+ rotary screw vacuum pumps give users energy savings of around 50% compared to traditional rotary vane pumps.

Atlas Copco’s GHS VSD+ Series is a range of new-generation highly efficient, intelligent vacuum pumps with VSD based on the proven plug-and-play design principles of Atlas Copco compressors. The new vacuum pumps have been designed by vacuum engineers to deliver peak performance at operating pressures commonly found in industrial applications.

The state-of-the-art VSD technology combines with an innovative inlet control valve to increase efficiency and dramatically reduce lifecycle costs. Offering significantly better performance against benchmarked oil-sealed and dry vane vacuum pumps, GHS 350-900 VSD+ rotary screw vacuum pumps are quiet in operation with the built-in efficiency contributing to sustainable productivity.

The vacuum pump conforms to energy management and environmental commitments according to ISO 50001/14001. Ultra-high oil retention at all operating pressures from ultimate pressure to atmospheric pressure reduces environmental impact.

Key advantages of the GHS 350-900 VSD+ rotary screw vacuum pumps include small footprint; low noise operation; energy recovery minimising hot air in the workplace, avoiding the usual problem of hot air in air-conditioned production environments; market-leading oil retention optimising quality of the exhausted air and contributing to employee well-being; and ability to prevent oil spills on the factory floor, leading to a significantly cleaner working environment.

The plug-and-play design of the GHS VSD+ Series rotary screw vacuum pumps assures easy and fast installation that also saves time and space. Some of the new features have been added in the vacuum pumps to provide extra efficiencies. For instance, the newly designed vacuum specific element offers a significantly longer lifetime than a screw compressor and vane pumps. The new patented inlet control valve provides modulating vacuum control in conjunction with the VSD drive to minimise energy consumption.

Atlas Copco's GHS VSD+ series will be expanded with sizes up to 2,000 m³/hr to be available by summer of 2015, and up to 4,500 m³/hr in early 2016.

The complete GHS VSD+ range is equipped with the Atlas Copco Elektronikon monitoring system, a state-of-the art monitoring system for vacuum pumps, as well as SMARTlink for remote monitoring.
