Pittsburgh Specialty Gas Equipment Spotlight: Gas Purifiers


At Greco Gas, PurityPlus® specialty gases for commercial, industrial, medical, scientific, and agricultural use are what we’re primarily known for selling. But customers have no doubt they also can depend on us for everything needed to move, store, regulate, and work with those gases safely. One such kind of equipment they appreciate is our line of gas purifiers.

The Pittsburgh semiconductor industry particularly calls on us for point-of-use gas purifiers that extract impurities down to part-per-trillion (pptV) levels. This kind of purity is requisite for producing not only semiconductors but also all manner of display, LED, and solar products.

Specifically, we provide …

  • high-pressure gas purifiers, these built for use in all types of laboratory and industrial situations where oil or water must be kept out of a gas to enhance its efficacy and avoid equipment shutdown.
  • gas purifiers that, while similar to our high-pressure models, are made to take care of higher capacities at a reduced working pressure.
Note that these two kinds of purifiers must used along with specially engineered replaceable cartridges containing one of various adsorbents. As determined by the cartridge/adsorbent ordered, these purifiers can exclude more than simply 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 specially created to exclude up to 1% of oxygen from a hydrogen stream down to a level below 1 ppm. They do this by catalytic action. If the catalytic materials aren’t fouled (particularly by sulfur and halogens), they’ll function pretty much permanently without requiring regeneration.

If you’re in the market for  trustworthy gas purifiers for your Pittsburgh operation, get hold of Greco Gas, your local PurityPlus® specialty gas supplier today. Remember: specialty gases aren’t our only specialty!
