Jonathan Wilkinson, President and CEO of QuestAir said that the H-3200 pressure swing adsorption ("PSA") system will be included in a hydrogen plant that Hydro-Chem is supplying to an industrial customer in Eastern Europe.

"This is our first sale of a full-scope PSA system to Hydro-Chem, and follows the manufacturing license agreement that we signed with Hydro-Chem earlier in 2006 which covered our larger capacity H-3100 PSA systems," said Wilkinson. "We are extremely pleased to extend our commercial relationship with Hydro-Chem to include our smaller capacity H-3200 systems."

Dennis Norton, Hydro-Chem's president said, "QuestAir's H-3200 PSA hydrogen purifier has established a market-leading position in hydrogen purification market, and we are very pleased with the performance and cost benefits that the H-3200 offers to Hydro-Chem's smaller-capacity hydrogen plants."
