Edwards nXDS is the great new shape of dry vacuum pumping The nXDS has taken scroll vacuum technology to the next level. Improved performance, exceptional pumping capability, quiet operation and extended service intervals make nXDS the ultimate dry choice. Quiet operation Better working environment Hermetically sealed for a lubricant-free vacuum environment Contamination free process and no oil to dispose of Low power consumption Low cost of ownership Intelligent and easy to use controls Flexibility of operation Superior vapour handling Wider range of applications Long service intervals Maximised...

nXDS scroll pump sectional view Optimum bearing placement for long lifetime and easy replacement High efficiency radial air-gap motor for low power consumption Wide range voltage input with automatic selection for simple operation Easy to use manual control buttons Standby speed control buttons for efficient processtuning USB port for service use only Remote control interface for convenience of operation nXDS Dry Scroll Pump

Hermetic bellows sealing for contamination free vacuum Optimised scroll profiles for each model to maximise performance Advanced tip-seal technology for long service lifetime Thermally controlled fan for reduced noise nXDS Dry Scroll Pump

Performance nXDS has been designed to combine the latest advances in scroll technology with an intelligent drive coupled with the long established, truly dry, hermetically sealed mechanism of the XDS series. Class leading pumping speeds are an improvement over previous XDS models and, with the drive, are of course consistent worldwide. Likewise, ultimate vacuum pressures which are below 10-2 mbar are now comparable with those of oil-sealed rotary vane pumps – without the inconvenience of oil. Hermetic sealing ensures that the vacuum environment is not contaminated by bearing lubricant and, conversely,...

Pump controller The advanced controller allows for several modes of control: Manual Push button START, STOP and STANDBY. Accurate speed control of 1% of maximum running speed. Parallel remote From your own control system via the 15 way d-sub connector giving the same START, STOP and STANDBY with the option of analogue speed control. Serial communication remote Option of either RS232 or RS485 with a choice of Edwards’ proprietary ‘DX’ protocol or industry standard Modbus protocol. A USB port has been included for service use only. The pump controller is able to accept voltages from 100-127 and...

Controllers The TIC (Turbo and Instrument Controller) automatically recognises the nXDS pump when connected to the backing pump connector as the controller adopts serial communications mode when connected to the nXDS. There is no need to use a relay box to interface to nXDS. Speed control and pump run hours etc can be readily accessed from the display. The TIC can also control an nEXT turbopump plus, up to three gauges at the same time as a nXDS pump. Customers already owning a TIC can upgrade their software to enable interfacing to nXDS.
