Western Michigan Specialty Gas Equipment Spotlight: Gas Purifiers


It’s certainly no secret that our main concern at GTW is selling specialty gases for commercial, industrial, medical, scientific, and agricultural use. But customers are well aware they also can depend on us for everything necessary to transport, stock, monitor, and use those gases safely. One such type of equipment they certainly go for is our line of gas purifiers.

The Western Michigan semiconductor industry especially comes to us for point-of-use gas purifiers that extract impurities down to part-per-trillion (pptV) levels. This kind of purity is imperative for making not only semiconductors but also [[various display, LED, and solar products.

In particular, we provide …

  • high-pressure gas purifiers, these built for use in all types of laboratory and industrial projects where oil or water must be kept away from a gas to increase its effectiveness and avert equipment shutdown.
  • gas purifiers that, while much like our high-pressure models, are built to handle higher capacities at a reduced working pressure.
Both of the above must used with specially made replaceable cartridges that contain one of a host of different adsorbents. Relevant to the cartridge/adsorbent provided, these purifiers can exclude more than just 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 designed to remove up to 1% of oxygen from a hydrogen stream down to a level lower than 1 ppm. They accomplish this by catalytic action. If the catalytic materials aren’t fouled (particularly by sulfur and halogens), they’ll perform pretty much forever without requiring regeneration.
