Brazing (Heat Treating)
Nitrogen Generator for Brazing: Joining metals by flowing a thin capillary layer of non-ferrous filler metal into the space between them. Bonding results from the intimate contact produced by dissolution of a small amount of base metal into the molten filler metal, without fusion of the base metal. The term brazing is used when the temperature exceeds some arbitrary value, typically 475ºC (880ºF). Furnace atmospheres for brazing include Exothermic and Endothermic gas (including nitrogen-diluted Endothermic gas), nitrogen, nitrogen/hydrogen mixtures, dissociated ammonia (including nitrogen-diluted dissociated ammonia), hydrogen and vacuum (partial pressure). The term soldering is used when the temperature is lower than this arbitrary value. Welding is another joining process that is performed at temperature in which melting of both the base metal and the filler metal occur.
Introducing the N2-GEN® – HTS Nitrogen Generation System specifically designed for use within Heat Treating, Brazing and Sintering processes. Designed & Manufactured by South-Tek Systems, the leader in Nitrogen Generation Technology.
Nitrogen gas has been utilized in the Heat Treating Industry for many years in a variety of applications including nitrogen blanketing, nitrogen purging (normal & safety), inert gas processing and much more. Nitrogen gas is often required in the production process of both primary goods (billets, ingots, slabs) and secondary goods (component part manufacturing). South-Tek’s tried, tested and proven PSA Nitrogen Generation Technology safely separates the readily available Nitrogen gas from within the air we breathe.
The air contains 79% Nitrogen; our systems mechanically filter out the other gases, concentrating the N2 into a storage tank for your process usage. Clean, dry compressed air enters one of the two adsorption vessels, containing Carbon Molecular Sieve (CMS). Smaller oxygen and residual molecules are adsorbed into the CMS, allowing the larger Nitrogen molecules to pass through into a storage tank for later process use. Upon saturation, a second absorption vessel is brought on line while the first one regenerates and releases its trapped gas.
