QuestAir to supply hydrogen purifier to Hydro-Chem for Eastern European hydrogen plant

VANCOUVER, B.C. – QuestAir Technologies Inc. (AIM: QAR; TSX: QAR) announced today that it will supply one of its H-3200 hydrogen purifiers to Hydro-Chem, a leading global supplier of industrial hydrogen plants. Hydro-Chem is a division of Linde BOC Process Plants LLC.

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.

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.”
