PNEUMATICS In applications requiring a clean central vacuum, the new standardised vacuum system NDi from Leybold is claimed to ensure a reliable supply. The system is based on the dry-running NOVADRY screw pump, which is robust over the entire pressure range, and the integrated VAControl CAB controller for smart control. The range of applications for the NDI central system includes food and packaging processes, research & development, vacuum conveying systems as well as medical and laboratory applications. Hygiene, economy, reliability In these areas of application, hygiene, economy, reliability, compactness and ease of operation are important to the operators. For vacuum values such as the final pressure or pumping speed, process- dependent flexibility is required. “In view of these requirements, the strengths of our oil-free, air-cooled screw vacuum pump NOVADRY come into their own,” says product manager, Dennis Schröder. “In addition to accumulating air and water vapour mixtures, the robust screw vacuum pump introduced in 2019 tolerates, among other things, 32 HYDRAULICS & PNEUMATICS September 2022 www.hpmag.co.uk Central vacuum system for food & packaging, research & development and analytical application s contamination of the gas flow with organic acids, food additives or other residues. This ensures long operating times.” Smart control of all processes By equipping the standardised NDi pump systems with the VAControl CAB, Leybold ensures intelligent control of all processes. Continuous data recording ensures maximum production quality, with the encrypted pump data available regardless of location. Individual users can access the server at any time – users can choose between local, remote or cloud connectivity. Direct control of the system is possible via various interfaces and end devices. Maintenance and service recommendations of the vacuum system The intelligent software functions that Leybold has stored in the control system are all practical and user-friendly and serve the entire process planning: For example, they can be used to control the starts and stops of several pumps, the pressure control and the cloud communication via GENIUS. The maintenance and service recommendations of the vacuum system are generated by the powerful computer depending on the operating times. Strong vacuum performance The standardised NDi vacuum systems are available fully assembled in different pumping speeds: as ND 400i with 400 m3/h pumping speed and as ND 600i version with 600 m3/h pumping speed. A strong vacuum performance up to a working pressure of 5 mbar, intelligent pressure adjustment and control of the target pressure complete the features of the smart NDi vacuum package from Leybold. This makes the NOVADRY VDi pump system with integrated VAControl CAB suitable for the following applications: Food and packaging processes (i. e. packaging of red meat with modified atmosphere (MAP)) Research & Development (i. e. to evacuate a chamber) Pick & Place (i. e. picking glas windows with a roboter) Production of electronic components. www.leybold.com/en-uk
