Lean Exothermic Model XH Inert Atmosphere Generators

Check up to five results to perform an action.


Gas Atmospheres inert gas generators are completely piped, wired and assembled in a “packaged” unit, providing ease of installation and maintenance. The two-pass combustion chamber with a shell-and-tube heat exchanger, provides effective cooling to within 15° F (7° C) of the cooling water temperature. Stainless steel, Type 304, is utilized in construction of the firing chamber, return flue tubes and tube sheets to provide maximum equipment life.

Safety controls are provided for automatic shutdown in event of utility failure.

In addition to the standard features...Gas Atmospheres will design and engineer equipment to suit specific applications.

Specifications on standard models are available upon request.

Use of the inert gas generators include:

  • Purging & blanketing of storage tanks
  • Inert gas packaging of foods
  • Bright annealing of non-ferrous alloys
  • Preventive insect or rodent attack in silos
  • Processing requiring LOW OXYGEN in gas.
Gas Atmospheres inert gas generators feature:
  • Fused interlocking door disconnect
  • Water flow switch
  • Ultra-violet flame scanner
  • Low & High & fuel pressure switches
  • Product gas relief regulator
  • Unit-piped and wired as a package
  • NEMA-12 electrical enclosure with NEMA-1 components
  • Timed purge prior to ignition with “SAFE START” indicator
In addition to the standard features, the following auxiliary equipment is available:
  • Oxygen and combustibles analyzers
  • Refrigerant
  • Heat recovery - Steam or hot water
  • Catalyst purifier to reduce oxygen to less than 10 PPM.
