Cylinder Passivation System

New WELDCOA Specialty Gas Product


Cylinder Passivation System

Passivation System 1


This is a new specialty gas product offering, exclusively designed and built by Weldcoa. If you are interested in this system, please contact us at sales@weldcoa.com to discuss further.

Ensure the Highest Level of Cylinder Preparation

Our new cylinder passivation system is designed for applications that require the highest level of prep before a fill, such as reactive gas mixtures for environmental monitoring that may be in the single part per million range with a very tight blend tolerance. This system would be used to further prepare cylinders that have already been processed through a bake out oven or similar prep system.

The cylinders that come off of this unit can be under a deep vacuum and sent to fill right away or purged with positive pressure and stored for later. 

Features and benefits

  • All process piping orbitally welded and constructed of high quality 316L stainless steel
  • High integrity connections throughout for a leak free system
  • ½” high integrity diaphragm valves designed for high flow through system
  • Vacuum pump and all process piping installed and tested to ensure system can reach single digit micron/mTorr vacuum levels
  • Manifold designed to allow for purging and vacuuming of 100% of the process piping upstream and downstream of all valves/ regulators to allow the use of pyrophoric gasses (gasses that spontaneously combusts in the presence of air)
  • Large diameter process piping for high vacuum conductance
  • Integrated manifold for connecting “Pickling” gases to manifold for purging
  • All connections (electrical and mechanical) easily made in the field
  • 10 cylinder linear manifold incorporated
  • m/Torr digital vacuum gauge suitable for rated environments
  • Each unit is shipped fully assembled and pre-tested.
  • Made in the USA
