ITME opts for two HP-480 VPurge systems from Johnson Matthey

Johnson Matthey Gas Purification Technology (JM-GPT) group of West Chester, PA, USA has supplied two HP-480 VPurge systems to ITME in Warsaw, Poland, for the purification of hydrogen used in the epitaxial growth of n-type and p-type Silicon Carbide (SiC) layers for high-power and high-frequency devices.

Dr Wlodek Strupinski, director of the Semiconductor Compounds Epitaxy Laboratory at ITME said, “ Johnson Matthey’s hydrogen purifiers are capable of providing 99.9999999 percent pure hydrogen for Silicon Carbide Reactors. That coupled with JM’s extensive knowledge and experience in palladium membrane technology made them the purifier of choice for ITME…in fact, we have been using JM purifiers since 1980, due to their quality and reliability.”

JM-GPT says its VPurge system offers rapid and complete purging of hydrogen from palladium (Pd) membrane purifiers, and total hydrogen removal in the event of power outages and emergency shutdowns.
