Emergency Purge (Heat Treating)
Nitrogen Generator for Emergency Purge. The introduction of an inert gas, typically nitrogen gas, into a furnace in which an abnormal condition has developed due to, for example, a power failure or load transfer malfunction. Often times a smaller nitrogen generator package can be paired with a larger nitrogen gas storage tank to accommodate an emergency nitrogen purging to cover all furnaces in the plant. Contact us with help in sizing an Emergency Purge System for your facility.
The purposes of an emergency purge are:
- to maintain the furnace under positive pressure
- to limit air egres
- to remove a combustible atmosphere from the unit and replace it with a non-flammable one, often over a concern that the furnace temperature will drop below the atmosphere self-ignition temperature of 760ºC (1400ºF)
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.
