ILT Energia column filters provide a simple and proven solution for drying the gaseous flow of hydrogen and/or oxygen using hygroscopic salt or adsorbent material that enables Dew point levels as low as -40 °C. Depending on the specific application, it is possible to customize the filter configuration to dry either hydrogen or oxygen individually, or to treat both gases simultaneously.To complete the system, the filters are equipped with backflow preventer safety valves and condensate purge valves.
