Wherever hygiene, economy, reliability and compactness are required, the new, standardized NDi vacuum system from Leybold ensures a reliable supply. The vacuum 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, and medical and laboratory applications.
Process-dependent flexibility is required for vacuum values such as the final pressure or pumping speed. "In view of these requirements, the strengths of our oil-free, air-cooled Novadry screw vacuum pump in particular come into their own," says the product manager responsible, Dennis Schröder. In addition to air and water vapor mixtures, the robust screw vacuum pump tolerates contamination of the gas stream with organic acids, food additives or other residues. This ensures long operating times.
