GXS, IDX and Drystar® 80 Pumps8Page278Edwards is a market leader in dry pump technology and haspioneered the use of dry vacuum in some of the harshestapplications.The Edwards GXS range incorporates our unique screw technologywith a world leading high efficiency drive to achieve excellent vacuumperformance with low running costs.The IDX uses the very latest in double ended screw pumpingtechnology, whilst the Drystar 80 range utilises a reverse clawmechanism, proven over more than 10 years and 100,000installations worldwide. Both provide reliable and economicalsolutions to the demands of today's industrial processes.The product range is available from 80 m 3 hr -1 / 47 ft 3 min -1 to3450 m 3 hr -1 / 2031 ft 3 min -1 .Why Dry?Dry Vacuum pumps - why not you? The competitive nature of today’sbusiness means changes are required to improve performance, lowercosts, and provide optimal process solutions. The Dry pumpingsolution is the change from traditional oil sealed pumps to a proventechnology for this industry. Edwards, a world leader in dry pumptechnology, has demonstrated the ability to provide a low-cost,custom tailored solution to your vacuum application. The benefitsoffered by the GXS/Drystar 80/IDX Dry pumping solutions are:• Maintenance- Low capital cost and minimal maintenance requirements lead tolowest cost of ownership- Extended periods between user intervention- Lower consumable costs• Environmental- No oil disposal- No oil emissions into atmosphere• Performance- Very stable pumping speed gives repeatability to processes- Continuous pumping at atmosphere- Ability to handle particulates- Dry eliminates back-streaming, thus protecting reactive alloysfrom contamination- Significantly higher capacity for water vapour pumping thantraditional oil sealed pumps• Safety- Unobtrusive noise levels- No unsightly oil spills- No hazardous oil vapoursAll Edwards dry pump ranges are ideally suited to:• Metallurgy- Vacuum Induction Melting (VIM)- Precision Investment Casting (PIC)- Vacuum Arc Refining (VAR)- Electron beam welding- Vacuum sintering- Steel degassing• LED manufacture• Lithium Battery manufacture• Solar- Lamination- Silicon Crystal growing- Solar coating• Heat treatment- Hardening- Plasma & LP nitriding- LP carburization- Vacuum brazing• Coating- Roll coating- Architectural glass coating- Optical filters & lenses- Vacuum metallising• Drying- Lithium Ion Battery (Drying and Degassing)- Transformers, capacitors & cables- Leather- Spices & fragrances- Nuclear industryand many more.With such a range of pumping speeds combinations and applicationsavailable, Edwards retains a comprehensive ApplicationsEngineering capability and are able to offer a solutions package thatincludes:• Process design• Equipment specification and selection• Safety and operating procedures• Vacuum system and control integration• Commissioning adviceSolutions EngineeringShop online at www.edwardsvacuum.comThe range and complexity of industrial applications means a 'one sizefits all' policy does not result in system optimization. A detailedappreciation of the process, environmental and safety issues isrequired to tailor systems to match performance and process.Applications Design & Support Edwards comprehensive designservice is based on in-depth knowledge of the industries andapplications involved. This expertise is held in the highly focused andexperienced applications team, which consists of a CentralApplications Group supported by a regional network of ApplicationsSpecialists. Proprietary software is used to define pumpingrequirements and a suite of optional accessories or modules areavailable. For larger or more unusual applications a customengineering service is available.Solutions could cover:• Process design• Equipment selection• Safety and Operating Parameters• Integration with plant control system(s)• Commissioning advice and more...Contact your local office to request an initial discussion with anApplications Specialist. Typically, discussions will include gases /materials to be pumped, cycle times and duty pressures, systemcapacities, control systems, utilities, system footprint and all otheraspects of the vacuum system to ensure that we are able to offer themost effective solution for your application.
