Atlas Copco claims the GHS VSD+ series represents "a quantum leap forward" for vacuum technology, promising energy savings of 50% compared with conventional oil-sealed and dry vane vacuum pumps.
The GHS 350-900 VSD+ range, generating nominal displacement of up to 900m3/h, incorporates variable speed drive technology, which enables vacuum generation to adapt precisely to demand, according to Christoph Angenendt, communication manager of Atlas Copco's utility vacuum business unit.
Coupled with an innovative motor design, the new range sets new standards for energy efficiency of vacuum pumps, resulting in a dramatic reduction in total cost of ownership, he says.
Also on show at ComVac will be a prototype of the new GHS 1900 VSD+ vacuum pump, offering nominal displacement of 1900m3/h, which Angenendt says will soon be added to the vacuum range.
"From a technology and design viewpoint, the new vacuum pumps are based on Atlas Copco compressors, and therefore provide fully wired, complete systems in a single housing," states Angenendt.
"Compared to oil-sealed and dry-valve vacuum pumps, the new range provides noticeably greater performance, and these pumps are considerably quieter than comparable machines."
