Atlas Copco introduces new screw vacuum pumps, underlining its commitment to sustainable glass production. Thanks to their long service life and greatly improved oil cooling and retention, these robust pumps contribute to savings in production processes. Compared with existing technologies, their use has resulted in significantly reduced life cycle costs.
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 energyefficient units deliver higher volume flows per hour and kilowatt power consumption than vacuum pumps with comparable performance," explains Christoph Angenendt, Communications Manager Industrial Vacuum at Atlas Copco. It therefore makes particular sense to convert several decentralized 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 percent can be achieved in glass production compared to conventional rotary vane vacuum pumps. "The payback time for a converted system is correspondingly short," adds Christoph Angenendt.
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," says Christoph Angenendt, explaining the benefits for users.
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 minimizes 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“, Christoph Angenendt explains 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.
While the Elektronikon® Mk5 system allows integration into the user's plant management system, Atlas Copco's SMARTlink provides the ideal solution for remote monitoring. It simplifies maintenance and the provision of data also for service technicians to adjust operating settings in real time. Equipped with customer-oriented plug & play design principles and a compact design, the GHS VSD+ series is quick and easy to install. All necessary components are supplied to the users as a complete package.
