Technical Specification Sheet

Edwards nXDS15iR Dry Scroll Pump

  • Bearing shield ensures separation between process gases and bearing lubrication to ensure clean vacuum and no possibility of contamination.
  • Smart motor drive means consistent performance globally, pump overload protection and remote start/stop capability.
  • High flow gas ballast feature allows pumping of vapours including water vapour at up to 240 gh-1
  • Simple single sided scroll design allows maintenance to be done in minutes for low cost of ownership and maximum up-time.
  • Enhanced versions offer up to 20% lower peak power requirements during initial pump down.
The nXDS allows a wide range of control and communication options
The nXDS comes as standard with a manual, easy to use, gas ballast port
A perfect companion for your turbomolecular pump
With exceptional pumping capability, ultimate vacuum performance and state-of-the-art design features Edwards nXDS is the best performing pump in its class. nXDS improves on legacy XDS pumps by offering increased pumping speeds, combined with lower ultimate pressures, lower power consumption and lower noise - up to 20 times quieter than other pumps. Gas ballast allows for pumping of condensable vapours including, water, solvents, dilute acids and bases. nXDS pumps also feature the latest in tip seal technology giving significantly longer life between tip seal changes. Integrated inverter drive with auto sensing voltage input delivers optimized pumping performance globally.

Unlike the standard nXDS15i, the Edwards nXDS15iR is designed for specialist applications such as gas recirculation, rare gas pumping and recovery or other applications where the dilution of the pumped gas is undesirable, or where sealing is integral to minimizing potential gas loss.
