QuestAir's H-3200 is incorporated into a commercial on-site hydrogen generator supplied by HyRadix Inc., a Chicago-based company and a leading provider of on-site hydrogen generation systems and supply solutions. HyRadix's commercial Adeo(TM) hydrogen fuel generator replaces a prototype Adeo(TM) system that has operated at the SunLine Transit hydrogen station since 2004. The new hydrogen generator provides hydrogen fuel for SunLine's current hydrogen-powered vehicles, as well as supporting SunLine's plans for future expansion of its hydrogen bus fleet.

Jonathan Wilkinson, President and CEO of QuestAir said that QuestAir has had a long association with the SunLine Transit hydrogen station, having supplied a hydrogen purifier to an earlier hydrogen generator installed at the station in 1998.

"We are extremely pleased with the successful start-up of the H-3200 as part of HyRadix's Adeo(TM) hydrogen generator. The system performance has fully met expectations since installation, producing high purity hydrogen that meets the demanding purity specifications of the major fuel cell vehicle manufacturers."

The H-3200 unit was supplied under the terms of a supply agreement with HyRadix announced in June 2005.
