The getter only approach is ideal for facilities that already have a good quality hydrogen supply, but require ultra-high purity (UHP) quality hydrogen for critical processes.

The MegaTorr PS7 Series Heated Getter Hydrogen Gas purifiers utilize a heated getter process to provide ultra-high purity (UHP) gas. This simplified approach provides outlet impurity levels to < 1 ppb for O₂, CO, CO₂, H2_O, CH₄, and N2.

This purifier series is provided in three sizes flows up to 20, 40, and 100 Nm³/hr. Getter column replacement can be performed in the field by an authorized SAES Field Service Engineer.
