Performance nXDS has been designed to combine the latest advances in Scroll technology with an intelligent inverter drive coupled with the long established truly dry hermetically sealed mechanism of the XDS series. Class leading pumping speeds are an improvement over existing XDS models and, with the inverter 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. nXDS is available in four sizes: Hermetic sealing ensures that the vacuum...

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 connector has been included for future connectivity. The pump controller is able to accept voltages from...

Ordering information Standard product Corrosion resistant (C) variants (R) Variants without gas ballast Controllers and accessories 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 as an option, up to three gauges at the same time as a nXDS pump. Customers...
