Oil-sealed rotary screw vacuum pumps
With Variable Speed Drive (VSD) technology
GHS 1300-1900 VSD+ SERIES

THE INNOVATIVE TECHNOLOGY THAT MAKES IT WORK
1 ) Element • Highly efficient oil-sealed rotary screw. • Outstanding performance. • Robust design. • Element life is significantly longer than screw compressors and vane pumps.
2 ) Inlet control valve Provides modulating vacuum control in conjunction with the VSD+ drive to minimize energy consumption.
3 ) Atlas Copco’s Neos inverter • Atlas Copco’s in-house designed inverter for VSD+ machines. • A robust, aluminium enclosure for trouble-free operation in the harshest conditions. • Fewer components: compact, simple and user-friendly
4 ) Guaranteed oil retention • Optimum design for maximum oil retention. • Longer life because of managed performance means the vacuum pump never overloads the separators. • Innovative and patented oil separator design retains oil at
5 ) Energy recovery options • Allowing you to recover up to 75% of the power input. • Helping you to fulfil your energy management & environmental commitments according to ISO 50001/14001.
6 ) Elektronikon® monitoring system Elektronikon® is a state-of-the-art monitoring system for your vacuum pumps. It is simple and omprehensive, and leads to energy savings. It can also integrate your plant management system thanks to a remote monitoring option.
7 ) Canopy with hot-cool zones The GHS VSD Series features a canopy with a hot-cool design. It isolates all heat producing and temperature critical components (oil separator and element) from all other components. As cool running means higher reliability, this feature extends the lifetime of electronic components and leads to a longer Mean Time Between Maintenance (MTBM).
8 ) Easy to use, simple to maintain • The top cover of the oil separator has a unique hinge mechanism. It slips the cover to the side, allowing the oil separator filter to be changed easily and quickly. • A cleverly designed exhaust pipe (drip drain leg) enables the condensate to be collected in the discharge pipework at the outlet and can be drained via the outside of the canopy

VSD FOR 50% AVERAGE ENERGY SAVINGS* In almost every production environment, the need for vacuum fluctuates depending on different factors such as process changes, the time of day, week or even month. Extensive measurements and studies of demand profiles show that there are many substantial variants with regards to vacuum demand.
WHY ATLAS COPCO VARIABLE SPEED DRIVE TECHNOLOGY? • On average 50% energy savings with an extensive flow range (10-100%). • Reduced electrical installation costs (fuse and cable size). • Integrated Elektronikon® Graphic controller controls the motor speed and high efficiency frequency inverter. • Eliminates peak current penalty during start-up experienced with stop-start machines. • EMC compliance to directives (2004/108/EG
