MegaTorr^® Palladium Hydrogen Gas Purifiers

Our PD Series advanced palladium gas purifiers offer two to three times higher capacity than other models, with lower cost and improved durability for high-volume manufacturing processes.

Palladium acts as a catalyst causing hydrogen (H₂) gas molecules to dissociate into atoms upon contacting the membrane surface
The atoms are small enough to diffuse through the palladium membrane, driven by differential H₂ pressure across the membrane, they then recombine into molecules after passing through the membrane
Palladium provides a solid barrier with no breakthrough as compared to catalysts and getters that rely on chemical reactions on reactive surface areas
Optimized design provides sub-ppb performance in small footprints with flow rates up to 2,170 slpm (130 Nm³/hr)
Includes models PS7-PD05, PS7-PD1, and PS7-PD2 with various flow capabilities for all your application needs
