Designed for applications requiring continuous production of mixed gas

The Thermco® gas mixer is designed to mix two non-flammable and non-corrosive gases. The gas mixer is normally used with a process where the supply gases are drawn from bulk sources, and the mixture is produced on-site where it is supplied to the process by a pipeline.

Gases Applications

  • Carbon dioxide/Argon Oxygen/Argon Helium/Argon – Welding shield gas
  • Carbon dioxide/Nitrogen Oxygen/Carbon Dioxide – Food packaging
  • Helium/Nitrogen Helium/Air – Leak detection
  • Oxygen/Nitrogen – Blanketing atmospheres
  • Nitrogen/Argon – Lamp filling
