Indianapolis Specialty Gas Equipment Spotlight: Gas Purifiers


It’s surely no secret that our main concern at American Welding & Gas, Inc. is providing specialty gases for commercial, industrial, medical, scientific, and agricultural use. But customers recognize they also can depend on us for everything necessary to ship, store, monitor, and work with those gases safely. One such category of equipment they really go for is our line of gas purifiers.

The Indianapolis semiconductor industry definitely calls on us for point-of-use gas purifiers that take out impurities down to part-per-trillion (pptV) levels. This standard of purity is imperative for manufacturing not only semiconductors but also all kinds of display, LED, and solar products.

Specifically, we supply …

  • high-pressure gas purifiers, these models made for use in all kinds of laboratory and industrial projects where oil or water must be kept out of a gas to increase its utility and circumvent equipment shutdown.
  • gas purifiers that, while similar to our high-pressure models, are made to take care of higher capacities at a lower working pressure.
Both of these purifiers have to be used in combination with specially made replaceable cartridges that are filled with one of various adsorbents. Depending on the cartridge/adsorbent required, these purifiers can exclude more than oil and water from industrial process gases; they’re also capable of excluding water from inert gases and saturated hydrocarbons, excluding various particulates, and excluding water from unsaturated hydrocarbons – acetylene, for instance.
  • a series of gas purifiers specifically made to exclude up to 1% of oxygen from a hydrogen stream down to a level under 1 ppm. They achieve this by catalytic action. If the catalytic materials aren’t fouled (especially by sulfur and halogens), they’ll perform pretty much permanently without requiring regeneration.
