Exo Gas Generator

EXO-gas generators produces protective atmosphere for Heat Treatment furnaces. Lean Exo-gas or Rich Exo-gas is produced simply by changing the air to fuel ratio in burner.

Flow Range

We custom design our exo gas generators and offer these from flows ranging from 10 to 5,000 nm3/hr capacity.


Dew Point

Our exo gas generators are designed to deliver very dry gas with dew points as low as (-) 60°C.

Lean Exo-Gas

Lean Exo-gas is produced by burning of fuels at slightly lower sub-stoichiometric combustion air to fuel ratio. This Exo-gas is lean in CO + H2 content. Lean Exo-gas generators are suitable for non-ferrous metals heat treatment.


Rich Exo-Gas

Rich Exo-gas is produced by burning of fuel at high sub-stoichiometric combustion of air to fuel ratio. So the Exo-gas produced is rich in CO + H2 content. Rich Exo-gas generators are used for heat treatment of steel and also brazing and annealing applications.

Technology Features


Burner Technology

These gas generators are fitted with a specially designed Swirl Flame burner which gives soot free combustion and oxygen free Exo-gas even under sub-stoichiometric conditions. Burner is ignited by spark plug and flame is continuously monitored by UV-flame scanner.



By providing a Refrigerated dryer after Gas generator dew point of (+) 5°C is achieved. For (-) 60°C dew point, a Molecular Sieves dryer is provided.


Multiple Fuels

MVS exo gas generators are offered to operate on various fuel types including:

  • Natural Gas
  • LPG
  • Propane


Fuel supply to burner stops automatically and gas generator shuts down safely giving audio-visual alarm due to any problem like-low combustion air pressure, flame failure, low water flow or low fuel pressure.
