About Gastek
Serving industry since1993
33 years of designing and building plants that make nitrogen, hydrogen and oxygen on the sites where industry uses them.
In 33 years the work has stayed the same at heart: take air, ammonia or water, and turn it into the gas a process needs, at the flow, purity and pressure it needs, on the site where it is used.
01Engineer
Sized from your duty data.
Every plant starts from the process it serves: the flow, purity, pressure and dew point it needs, the application and the site. Gastek engineers set the cycle, choose the adsorbent and size the vessels and air package to that duty.
Air compressor
Ambient air, compressed
Dryer and filters
Oil, water and dust removed
Twin adsorbers
Carbon molecular sieve holds back oxygen
Buffer vessel
Steady flow and pressure
N₂ to process
95–99.999% purity
A PSA nitrogen plant, as Gastek sizes it. Hydrogen and oxygen plants follow the same discipline.
