EXPORT, Pa., June 28 /PRNewswire/ -- Oerlikon Leybold Vacuum (OLV), an ISO9001 certified company, offers vacuum pumps, research coating systems, leak detectors and related components for use in Photovoltaic manufacturing.  Our process experiences include vacuum generation for supporting crystal pulling and casting of silicon, deposition of thin-film coatings and lamination for today's solar modules.  

OLV recently announced the introduction of a second generation industrial dry-compressing screw-type vacuum pump line called DRYVAC®.  The new DRYVAC has evolved from one design platform comprised of models 650 S, 650 S-i and 5000 RS-i.  Multiple pumping system combinations are also possible for gaining increased pumping speeds and vacuum levels by incorporating the RUVAC® WH line of vacuum boosters.  Both DRYVAC and the RUVAC WH offer improvements in leak tightness, energy efficiency and physical stature over competitive brands.

The DRYVAC Difference

DRYVAC series dry-compression vacuum pumps have been designed to meet the special needs of applications in the Photovoltaic production chain, Industrial Coatings and other Process Industry applications such as Heat Treatments, Metallurgy and general degassing.  DRYVAC pumps are rugged, reliable and ready to fulfill demanding vacuum requirements where high vacuum, fast cycle times, energy efficiency, improved leak –tightness all in a space-saving design are required.  Single pumps can achieve 7.5 x 10-3 torr vacuum and over 2,900 cfm nominal displacement.  Enhanced performance is possible through use of a RUVAC booster stage.

The DRYVAC line is an environmentally friendly alternative to traditional oil-sealed rotary piston and vane pump style vacuum pumps.  With no lubricating oils contained in the pumps' compression stage, DRYVAC offers an improved operating environment with no oil emissions, reduced maintenance, with less down-time and disposal steps resulting in lower operating costs for our customers.  Along with appropriately selected vacuum boosters, turbo-molecular pumps and cryogenic pumps, DRYVAC can also support large volume research experiments where multiple dry-compression pump stages are required to achieve ultra-high vacuum levels where no chance for hydrocarbon contamination is desirable.  

DRYVAC 650 S version is our base unit featuring an integrated frequency converter that allows for a wide operating voltage and frequency drive with no need for motor protection switches.  The DRYVAC 650 S-i version includes the external pump housing, castors, integrated frequency converter, and an on-board PLC with touch screen.  The PLC allows for control and monitoring via intuitive menu navigation software and field bus.  DRYVAC 5000 RS-i includes all the aforementioned features plus an integrated vacuum booster that will achieve a nominal pumping speed of over 2,900 cfm.  Standard and optional integrated gas ballast and purge gas modules are also available on all DRYVAC models.  

Additional DRYVAC features include a hermetically sealed motor design without external shaft seals and motor bearings, water cooling, low power consumption, compact footprint, low noise level and UL listed materials.    

Other Oerlikon Leybold Vacuum Products in Action

The full-line vacuum portfolio offered by Oerlikon Leybold Vacuum supports other applications in the rough, medium, high and ultra-high vacuum regime.  Pumping technologies, systems and services include oil sealed rotary vane and piston pumps, dry compressing and oil-free pumps, vacuum boosters, turbo-molecular, oil diffusion & cryogenic vacuum pumps as well as customized pumping systems and research coating systems.  Repair & remanufacturing of all brands of vacuum pumps is also available.  We support vacuum applications in the Analytical, Industrial, Photovoltaic, Research & Development and Semiconductor sectors.

DRYVAC along with our UNIVEX research coating system will be presented at Intersolar North America, July 13 – 15, 2010 at Moscone Center in San Francisco, booth #8019.  For more information on the new DRYVAC and the full-line vacuum technology portfolio offered by OLV, please visit and .
