Purging with nitrogen reduces the risk of combustion, contamination and degradation caused by atmospheres containing oxygen and other undesirable substances.
Nitrogen is introduced continuously into the container or conduit to be purged, reducing the concentration of the component to be removed.
Nitrogen is introduced into the container to be purged acting like a piston, displacing the flow to be purged.
The pressure of the system is increased, and the gas is then released at a lower pressure. The amount of nitrogen purged pulls with it the contaminants to be separated.
The result of combining purging by dilution with different vacuum cycles.
