Edwards’ latest nXDS dry scroll vacuum pumps are said to be more reliable and require less maintenance than alternative pumps, resulting in less downtime and a lower cost of ownership. The range also has a lower environmental impact.
The nXDS oil-free vacuum pump has no lubricants in the vacuum and therefore has many advantages over oil-sealed pumps as there is no need for regular oil changes and users can benefit from low maintenance.
The pumps also feature intelligent control functions. Control modes include serial, USB, remote parallel and analogue as well as manual operation with simple up/down buttons. Full serial communications mode provides feedback about the state of the pump, enabling scientists to schedule routine maintenance at their convenience. It also assists with preventative maintenance regimes, as the pumps indicate when service is needed via a light indicator on the control panel.
The nXDS is quiet – with a low acoustic noise of 52dB(A) – and is up to 20 times quieter than some comparable pumps in the laboratory, the firm says. A standby mode reduces power consumption and allows users to set speeds ranging from 66% to 100% of full speed, saving money associated with energy use, while also improving carbon footprint.
‘The nXDS is based on some of the proven technologies of Edwards’ XDS dry scroll pump brought right up to date with much improved performance and increased functionality,’ says Ian Olsen, market sector manager (scientific) at Edwards. ‘Its green credentials and low cost of ownership make it the small dry pump of choice for today’s most advanced technologies, saving users time, energy and money.’
Users can choose from four sizes to suit their pumping requirements. The nXDS6i, nXDS10i, nXDS15i and nXDS20i have pumping speeds between 6m3hr-1 and 20m3hr-1.
The 10i and 15i in particular have base vacuums below 10-2 mbar. A gas ballast switch allows for applications involving water vapour to be easily managed.
