DY-KAST Supply offers a complete line of NITROGEN GENERATORS for the metal casting industry along with other industries such as gas and oil refining. Nitrogen is used to degass and clean non ferrous metals. Degassing of molten Aluminum alloys is a foundry operation aimed to remove Hydrogen dissolved
MAXIGAS and Midigas operate on the Pressure Swing Adsorption (PSA) principle to produce a continuous stream of nitrogen gas from compressed air.
Pairs of extruded aluminum columns are filled with carbon molecular sieve (CMS). Pre-treated compressed air enters the bottom of the ‘on-line’ column and flows up through the CMS. Oxygen and other trace gases are preferentially adsorbed by the CMS, allowing nitrogen to pass through.
After a pre-set time the on-line column automatically switches to regenerative mode, venting contaminants from the CMS.
Carbon molecular sieve differs from ordinary activated carbons in that it has a much narrower range of pore openings. This allows small molecules such as oxygen to penetrate the pores and be separated from nitrogen molecules which are too large to enter the CMS. The larger molecules of nitrogen by-pass the CMS and emerge as the product gas.
