The centralized system is so quiet that it almost whispers, has low maintenance requirements and saves space. Essen/Hanover, April Essentra Extrusion is one of the leading producers of customer-specific extruded plastic profiles in the Netherlands. At its plant in Buitenpost, the company develops tailor-made complete solutions from product design through to the production process. We cooperate closely with our customers, Marketing Manager Ilja Postma explains. And we have all the know-how and the technology required available in house which makes us unique. Extrusion is used to produce profiles with a defined cross section. The material is either pressed or drawn through a die. Plastic extrusion produces gases that we eliminate using a vacuum system, Tjitze van der Land, maintenance operative with Essentra, explains. This process is very important as product quality would otherwise be impaired. Central vacuum system reduces maintenance requirements The company has 40 production lines. The vacuum required for gas elimination was and still is generated centrally. The plant also features a large number of small pumps for other vacuum tasks. All in all, the maintenance requirements are very high. Initially, Essentra was looking for a new vacuum solution for gas elimination. The new system was Atlas Copco Kompressoren und Drucklufttechnik Atlas Copco Kompressoren und Drucklufttechnik GmbH Langemarckstraße Essen Tel.: +49 (0) Fax: +49 (0) Hotline Industrievermietung +49 (0) Geschäftsführer: Eckart Röttger HR B Essen 1792 UID DE Bank: SEB AG SEB Merchant Banking Postfach Essen Hotline Service: +49 (0) Info.Kompressoren@de.atlascopco.com Frankfurt / Main (BLZ ) Konto

2 2/5 to be stable, reliable and environmentally compatible. The company also wanted to reduce noise levels. Previously, we had used rather loud rotary vane pumps but our plant is located in a residential area, van der Land reports. That made it easy for us to select the new Atlas Copco vacuum pump, because it is really quiet. Moreover, Essentra was always searching for ways to organize production more efficiently. Instead of the old pumps, Essentra now uses a new Atlas Copco vacuum pump in its central vacuum system, a GHS 900 VSD + unit. This series offers high-efficiency, smart vacuum pumps with variable-speed drives; the main focus is on durability and plug and play design. In the development of the pumps, vacuum engineers aimed to obtain maximum performance at the operating pressures usually required in industrial applications. The new central vacuum system at the Essentra plant now provides the various production lines with a reliable source of vacuum. The GHS-VSD + vacuum pump has a 15-kilowatt motor and has replaced two older pumps each with a rating of 11 kw, says Mark Taylor, Marketing Manager of Atlas Copco s Utility Vacuum Business Line. In addition, variable speed control ensures the system always delivers the performance required. The energy savings are correspondingly high. Essentra expects savings in excess of 8,000 per year. And that is not the only benefit in terms of energy efficiency. The company also uses an energy recovery system from Atlas Copco which recovers waste heat from the Atlas Copco units to heat a public swimming pool on the other side of the road. In operation, the Atlas Copco vacuum pump has proven to be highly reliable. It also meets demands for lower noise levels. Essentra can now operate its plant seven days per week and even during the night without receiving any complaints from local residents. In addition, the new vacuum system also lowered maintenance costs.
