Pall Corporation Showcases Contamination Control and Water Reclamation Technologies for the Solar Energy Industry at Intersolar North America 2010

PORT WASHINGTON, N.Y., June 28 /PRNewswire-FirstCall/ -- Pall Corporation (NYSE: PLL), a global leader in filtration, separation and purification, will showcase economical and eco-friendly products and systems for the photovoltaic (PV) industry at Intersolar North America in San Francisco. The products are designed to help increase yield and reduce reworking times in solar cell manufacturing.

Purification of the process gases utilized in solar cell production has become critical to enhancing yields and conversion efficiency. Pall will feature two new media for its Gaskleen® purifier assemblies. The AresKleen™ HCLP media is highly effective in removing trace moisture down to < 15 parts per billion (ppb) levels from HCl gas used in the formation of trichlorosilane, a key ingredient in the production of polysilicon. Silane, also involved in making polysilicon as well as amorphous silicon PV cells, frequently contains trace siloxane and moisture. AresKleen SIP medium reduces these detrimental contaminants to sub-ppb levels. All Pall purifiers have integrated, highly efficient particle filters.

"The Pall GasKleen purifier with SIP material was evaluated by CVD Equipment Corporation and was found to lower dopant metal contaminants (As, P, Al and B) in a low grade silane line, resulting in improved silicon-epitaxial layers with impurities in the parts per trillion atomic (ppta) range," said Karlheinz Strobl, VP of business development, CVD Equipment Corporation. "We, therefore, find the Pall Purifier to be eminently capable of achieving below ppb levels of these contaminants in hydrogen, argon and silane process gases utilized in silane epitaxial film deposition."

Pall will present its fully automatic Water Reclaim System for recovering over 90% of deionized water used during silicon ingot shaping. The system efficiently and economically removes the resultant silicon fines without the need for chemical additives, providing essentially particle-free water for cost-effective recycling. A major supplier of shaping and grinding tools for the solar industry highly recommends this reclaim system.

Another exhibit will highlight Blowback Filtration Systems for the protection of CZ ingot puller vacuum pumps. A display of innovative filters and uniquely designed housings for chemical and water filtration will round out Pall's showcase at Intersolar. The systems and products provide long-term service without the interruption of frequent change-outs, increasing uptime and reducing maintenance costs for solar cell producers.
