Portland Specialty Gas Equipment Spotlight: Gas Purifiers


At Cryo-Source, PurityPlus® specialty gases for commercial, industrial, medical, scientific, and agricultural use are what we’re primarily known for selling. But customers know they also can depend on us for everything needed to move, store, regulate, and use those gases safely. One such category of equipment they truly go for is our line of gas purifiers.

The Portland semiconductor industry definitely calls on us for point-of-use gas purifiers that eliminate impurities down to part-per-trillion (pptV) levels. This measure of purity is necessary for manufacturing not only semiconductors but also [[various display, LED, and solar products.

Specifically, we provide …

  • high-pressure gas purifiers, these models designed for use in all sorts of laboratory and industrial research where oil or water have to be kept away from a gas so as to boost its utility and reduce the possibility of equipment shutdown.
  • gas purifiers that, while similar to our high-pressure models, are built to handle higher capacities at a lower working pressure.
Both of these purifiers have to be used in combination with specially made replaceable cartridges that hold one of various adsorbents. As determined by the cartridge/adsorbent ordered, these purifiers can exclude more than oil and water from industrial process gases; they also have the ability to exclude water from inert gases and saturated hydrocarbons, exclude many particulates, and exclude water from unsaturated hyrocarbons, such as acetylene.
  • a series of gas purifiers specifically created to exclude up to 1% of oxygen from a hydrogen stream down to a level under 1 ppm. They achieve this by catalytic action. As long as the catalytic materials aren’t fouled (particularly by sulfur and halogens), they’ll perform pretty much permanently without requiring regeneration.

If you want  quality gas purifiers for your Portland operation, get hold of Cryo-Source, your local PurityPlus® specialty gas supplier today. Remember: specialty gases aren’t our only specialty!
