NITROGEN GENERATOR RANGE
PSA (PRESSURE SWING ADSORPTION)
Pressure Swing Adsorption (PSA) processes rely on the fact that under pressure gases tend to be attracted to solid surfaces, or adsorbed. The higher the pressure, the more gas is adsorbed; when the pressure is reduced, the gas is released, or desorbed. PSA processes can be used to separate gases in a mixture because different gases tend to be attracted to different solid surfaces more or less strongly. If a gas mixture such as air, for example, is passed under pressure through a vessel containing an adsorbent bed that attracts oxygen more strongly than it does nitrogen, part or all of the oxygen will stay in the bed, and the gas coming out of the vessel will be enriched in nitrogen. When the bed reaches the end of its capacity to adsorb oxygen, it can be regenerated by reducing the pressure, thereby releasing the adsorbed oxygen. It is then ready for another cycle of producing nitrogen.
CMS (CARBON MOLECULAR SIEVE)
A molecular sieve is a material containing tiny pores of a precise and uniform size that is used as an adsorbent for gases and liquids.
Molecules small enough to pass through the pores are adsorbed while larger molecules are not. It is different from a common filter in that it operates on a molecular level and traps the adsorbed substance. For instance, a water molecule may be small enough to pass through the pores while larger molecules are not, so water is forced into the pores which act as a trap for the penetrating water molecules, which are retained within the pores. Because of this, they often function as a desiccant. A molecular sieve can adsorb water up to 22% of its own weight.[1] The principle of absorption to molecular sieve particles is somewhat similar to that of size exclusion chromatography, except that without a changing solution composition, the adsorbed product remains trapped because in the absence of other molecules able to penetrate the pore and fill the space, a vacuum would be created by desorption.
Often they consist of aluminosilicate minerals, clays, porous glasses, microporous charcoals, zeolites, active carbons, or synthetic compounds that have open structures through which small molecules, such as nitrogen and water can diffuse.
FEATURES
• Low payback period
• Plug & Play
• Low maintenance
• Auto-standby mode
• PLC controlled with digital display
*Due to our modular construction and the flexible equipment technology it is possible to consider additional requests for bespoke solutions with different flows.
