WHAT IS THE LIFETIME OF THE PURIFIERS?
The palladium membrane technology used in the HP and PSH Series purifiers stops impurities on the inlet side and the impurities are vented, not adsorbed. Therefore, the palladium technology has a theoretical unlimited lifetime. IN practice, some purifiers may require replacement of the palladium tubes due to fatigue in high-volume, demanding applications. For these applications, life expectancy of the palladium membrane in hydrogen purifiers may be 5 years. Zirconium getter used in the PureGuard Wall Mount Heated Getter purifiers, operating at the nominal flow rate with inlet gas quality of 99.999%, have a normal life expectancy of two years. The getter beds can be replaced to provide continued life. Catalytic media used in the PureGuard catalytic purifiers, provided they are properly maintained and regenerated, can have unlimited life.
