Indianapolis Specialty Gas Equipment Spotlight: Gas Purifiers06/05/2018 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 comes to us for point-of-use gas purifiers that extract 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. To be specific, we supply … high-pressure gas purifiers, these models designed for use in all kinds of laboratory and industrial research where oil or water must be kept out of a gas to increase its usefulness and prevent 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.Each of these purifiers have to be used in combination with specially designed replaceable cartridges that are filled with one of various adsorbents. As determined by the cartridge/adsorbent required, these purifiers can eliminate more than oil and water from industrial process gases; they also have the ability to eliminate water from inert gases and saturated hydrocarbons, eliminate many particulates, and eliminate water from unsaturated hyrocarbons, such as acetylene. 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 corrupted (especially by sulfur and halogens), they’ll perform pretty much permanently without requiring regeneration. If you need quality gas purifiers for your Indianapolis operation, get hold of American Welding & Gas, Inc., your local PurityPlus® specialty gas supplier today. Remember: specialty gases aren’t our only specialty!
