In purposes requiring a clear central vacuum, the new standardised vacuum system NDi ensures a dependable provide. The innovation from Leybold is based on the dry-running NOVADRY screw pump, which is robust over the whole pressure range, and the built-in VAControl CAB controller for sensible control. The range of functions for the NDI central system contains meals and packaging processes, analysis & improvement, vacuum conveying systems in addition to medical and laboratory functions.
Hygiene, economic system, reliability
In these areas of software, hygiene, financial system, reliability, compactness and ease of operation are important to the operators. For vacuum values corresponding to the ultimate stress or pumping velocity, process-dependent flexibility is required. “In view of those necessities, the strengths of our oil-free, air-cooled screw vacuum pump NOVADRY come into their own”, emphasises the accountable Product Manager, Dennis Schröder. “In addition to accumulating air and water vapour mixtures, the strong screw vacuum pump introduced in 2019 tolerates, among other things, contamination of the fuel circulate with natural acids, meals additives or different residues. This ensures lengthy working times,” Schröder continues.
Smart control of all processes
By equipping the standardised NDi pump methods with the VAControl CAB, Leybold ensures intelligent control of all processes. Continuous information recording ensures most manufacturing high quality, with the encrypted pump information available no matter location. Individual users can access the server at any time – customers can choose between native, distant or cloud connectivity. Direct control of the system is possible via various interfaces and finish units.
Maintenance and repair suggestions of the vacuum system
The clever software program capabilities that Leybold has saved within the control system are all sensible and user-friendly and serve the complete process planning: For instance, they can be utilized to regulate the begins and stops of several pumps, the stress control and the cloud
communication by way of GENIUS. The upkeep and service suggestions of the vacuum system are generated by the powerful computer relying on the working times.
Strong vacuum efficiency
The standardised NDi vacuum techniques can be found totally assembled in several pumping speeds: as ND 400i with four hundred m3/h pumping velocity and as ND 600i model with 600 m3/h pumping speed. Fast as a lot as a working strain of 5 mbar, intelligent pressure adjustment and management of the target stress complete the features of the smart NDi vacuum package from Leybold.
