Edwards predicts future trends in vacuum systems at AVS

CRAWLEY, UK (22 September 2009) – Vacuum pump and abatement specialist Edwards will be presenting its predictions on the future evolution of vacuum process pumps at the AVS 56th International Symposium and Exhibition in San Jose, US in November.

The company, which celebrates its 90th anniversary this year, will consider the key drivers behind today’s vacuum pump technology and discuss future developments in a paper entitled ‘Vacuum Processing for the 21st Century’. This will be presented on Monday November 9 2009 by Dr Stephen Ormrod, Chief Technology Officer, and Nigel Schofield, Technical Manager for Core Technology.

The ability to design and machine complex, high precision shapes has already led to the proliferation of different pumping mechanisms, such as Roots, Claw, Screw and Scroll. Rotational speeds are limited by conductance and so, while future pump generations will run at increasingly higher speeds, analysis shows that many pumps are already approaching their ceiling, and some mechanisms will win out over others.

Edwards believes product design will be driven by the demands of a few critical and rapidly growing applications: semiconductor and solar panel manufacture, scientific instrument development and high purity steel processing.

The continuing need to increase pump safety and reduce carbon footprint will also play a significant role. Designers will need to be more inventive in terms of cooling and reducing purge dilution gases, as well as reducing pump power consumption, to reduce the contribution of vacuum pumps to global warming. Manufacturers such as Edwards will also need to reduce their side of the carbon footprint through, for example, not adding electronics unless they can be used to reduce consumption during the product’s life.

“Vacuum processing has come a long way since it was first developed for lamp manufacture at the beginning of the 20th century,” says Nigel Hunton, Edwards chief executive. “The inventors of the early mercury based technology would hardly recognise today’s dry and turbo molecular pumps, and we now use vacuum in a vast range of industrial applications.

“The challenge now is to use techniques such as computer modelling to design a whole new generation of pumps that will make a further step change in what we can do with vacuum.”

A Flash presentation on the 90-year history of Edwards is now available on the company’s website, www.edwardsvacuum.com.
