[labnetwork] N2 Pressure Builder

[Paolini, Steven]

Travis,
  Does this application use a lot of volume? If not, would you consider using an N2 cylinder with a high pressure output regulator? We have had a few pieces of equipment that required HP N2 and we were able to use a cylinder and regulator that could put out the required pressure. Of course, these applications did not require a lot of volume. Please keep in mind that it is CRITICAL to only use thickwall Stainless tubing and any other components that are rated for pressure that is higher than the regulator can put out.

Subject: [labnetwork] N2 Pressure Builder

Hello everyone,

Here at QNF we have a need to bring our house N2 pressure (sitting at 100psi) up to 500-750psi for a Nanonex NX2600 Nanoimprint tool. We currently utilize a Maximator system which is controlled pneumatically with house CDA. We are having a lot of issues with o-rings drying up and needing regular regreasing which becomes labor intensive. I am curious what everyone uses for N2 pressure builders in their facilities. Thanks!
