AC Vacuum Pumps GHS 350-1900 VSD+ Series With Variable Speed Drive

Product Specification

GHS 350-1900 VSD+ series
Oil-sealed rotary screw vacuum pumps with Variable Speed Drive (VSD) technology

Innovative, intelligent vacuum pumps
The GHS VSD+ Series is a range of new-generation,intelligent, oil-sealed rotary screw vacuum pumps with Variable Speed Drive (VSD) technology from Atlas Copco. Based on the well-known and durable plug-and-play design principles of Atlas Copco compressors, these vacuum pumps have been designed by vacuum engineers to deliver peak performance at your operating pressure.These unique products offer:
• Superior performance against benchmarked oil-sealed and dry vane vacuum pump technologies.
• Increased efficiency – State-of-the-art screw technology,Variable Speed Drive (VSD) and innovative motor design combine to produce a leap forward in efficiency.
• Quiet operation – Noise level is far below that of comparable technologies.
• Sustainable productivity thanks to built-in efficiency.
• Reduced environmental impact due to ultra-high oil retention at all operating pressures.

Perfect for diverse markets
The GHS VSD+ Series vacuum pumps are ideal for a range of applications in plastics, glass, bottling,canning, wood, packaging, printing and paper,meat packaging and many more. The GHS 350-900 VSD+ is the ideal solution when a dedicated pump is required in the production area. The GHS 1300-1900 VSD+ can also be set up as a dedicated solution but is normally used in the plant room of central vacuum system applications.
Low lifecycle costs
Here are two examples of the impressively low lifecycle costs of the GHS VSD+ Series:
• For replacement pumps, the GHS VSD+ Series offers a very low lifecycle cost (including service activities and energy).
Generally the payback time against existing oil-lubricated or multiple dry vane installations will be much less than two years, considering power and maintenance costs alone,without taking into account the ease of installation.

Outstanding, unmatched benefits
With these vacuum pumps you can potentially save 50%* or more in energy costs. They are among the
most energy-efficient oil-lubricated vacuum pumps on the market in the capacity range where some other
technologies (e.g. oil-sealed vane) start to become mechanically inefficient and expensive in terms of
capital expenditure.
As much as 90% of the electrical energy used by a vacuum solution is converted into heat.
With Atlas Copco’s integrated energy recovery system, it is feasible to recover up to 75% of that power
input as hot water without any influence on the machine’s performance. Through efficient usage of the
recovered energy, you obtain important energy cost savings and a high return on investment.

The innovative technology that makes it work

1.Element

• Highly efficient oil-sealed rotary screw.
• Outstanding performance in a robust design.
• Element life is significantly longer than screw compressors and vane pumps.

2.Inlet control valve
Modulating vacuum control in conjunction with the VSD drive to minimize energy consumption.

3.Atlas Copco’s Neos inverter(GHS 1300-1900 VSD+)
• 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 due to managed performance: the vacuum pump never overloads the separators.
• Innovative and patented oil separator design retains oil at <3 mg/m3 even under the greatest load.

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 comprehensive,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 potential energy savings of 50%* or more
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?
• Potential energy savings of 50%* or more 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).

Numerous configurations to match your application
Choose the version that matches your specific application requirements:

1.Standard
This machine focuses on delivering the exact performance you demand,at the lowest possible lifecycle cost. Ideal for applications where you need to maintain a set vacuum level (set point).

2.Humid
Suitable for high water content duties (up to 100%),for applications such as plastics, clay molding, drying pipelines, salad cooling, freeze drying etc.Configuration for high water vapor tolerance constitutes the humid version.

3.Turbo
This fast evacuation version enables faster cycle times – meaning more production. It’s ideal for meat, cheese and chicken packaging,
as well as cooling, freeze drying and general vessel evacuation applications.Turbo versions for fast cycling machines are available in 350, 585, 730, 1300 and 1600 sizes and come with upgraded motors and logic.
