Atlas Copco presented its new variable speed drive vacuum pump series GHS 3800-5400 VSD+ at Glasstec 2018 in Düsseldorf.

The GHS VSD+ series was developed according to Atlas Copco’s proven philosophy and is therefore designed as a durable plug-and-play system in a single housing. 

“The energy- efficient units deliver higher volume flows per hour and kilowatt power consumption than vacuum pumps with comparable performance,” explained Christoph Angenendt, Communications Manager Industrial Vacuum at Atlas Copco.

It therefore makes particular sense to convert several decentralised pumps to a central vacuum supply. With a GHS VSD+ system, users can significantly increase their productivity; Atlas Copco reports that energy savings of up to 50% can be achieved in glass production compared to conventional rotary vane vacuum pumps.

“The payback time for a converted system is correspondingly short,” added Angenendt.

Cleaner, cooler working environment

During development of the GHS 3800-5400 VSD+ Atlas Copco’s design engineers drew from the experience with the established GHS 350-900 VSD+ and GHS 1300-1900 VSD+ series. They also feature high efficiency and reliability and are available as a compact, user and service-friendly package.

The screw element at the heart of the pumps offers a lifetime guarantee, while intelligent turbo and humid versions ensure trouble-free performance even in the most difficult application environments.

The coarse vacuum pumps are optionally equipped with air or water cooling. An energy recovery option makes it possible to use the work of the IE3 high-efficiency motor.

A clear advantage in ergonomics: the oil retention improves the quality of the exhaust air compared to alternative technologies.

“This results in a cleaner and cooler working environment,” said Angenendt, explaining the benefits for users.

Minimal energy consumption, low maintenance requirements

The Elektronikon® Mk5 control system and the speed-controlled drive system (VSD+) make pump operation extremely economical: The pressure setpoint control function ensures that the pumps deliver the lowest possible vacuum flow to maintain the required vacuum. This minimises energy consumption and reduces operating costs over the lifecycle.

The low maintenance required by the series also contributes to efficiency. “There are no rotary vanes that need to be replaced, and the screw element is also maintenance-free for years. In addition, suction filters and oil separators can be replaced without dismantling the piping,” said Angenendt explaining the simple handling of the pumps.

Via SMARTlink software, the operator can dial in and inform himself in good time about the necessary maintenance work. The system displays all relevant information on an intuitively understandable, graphical user interface. The operating vacuum can be adjusted or changed by pressing a key. This allows users to easily adapt the pump’s performance to the respective process requirements.
