Specialty gas reflections… Proper sizing and selection of a changeover manifold is important to system performance


Many applications require a continuous supply of gas to the process, stopping the flow of gas during operations to replace empty cylinders is not an option.

The laser cutting operation is a perfect example of an application that may operate on a single eight hour shift basis but requires continuous flow throughout the operating period. Stopping production to replace empty cylinders can be costly – time is money.

There many other applications where the flow of gas must be maintained 24/7. Helium for gas chromatographs and carbon dioxide for incubators are two simple, but good examples where loss of gas flow can have very unwelcome results. These applications require continuous flow for long periods of time not only during working hours, but when the system is unattended in the evening and during weekends and holidays. Running a gas chromatograph (GC) out of helium carrier gas can result in costly repairs and days without analytical results. An incubator without carbon dioxide can result in destroyed samples and the loss of years of research.
