The advanced ExoFlex™ exothermic gas generator combines our patented ExoInjector™ fuel-injection generator control system with high-efficiency combustion technology to lower the operation and maintenance costs of producing high-quality exothermic gas for heat-treatment furnaces.


  • Lower operating costs and emissions waste from 20-80% of generator capacity
  • Automatic exothermic gas pressure control, eliminating regulator adjustments
  • Filter change indication improves system efficiency and operation time
  • Built-in software for ease of scheduling, maintenance and paperless data logging
  • Optional dedicated H2 sensor for monitoring and controlling percent hydrogen


The generator is equipped with the latest sensors to monitor dew point, unreacted methane, and energy consumption. The large-format touchscreen interface provides easy access to review generator operations, and the integrated paperless chart recorder tracks generator performance to meet production auditing requirements.

ExoInjector™ Control System

A precision gas mixing and control system for exothermic gas generators, the ExoInjector™ incorporates a patented fuel-injection design that utilizes electronic flow measurement and precise ratio control to consistently provide the ideal gas mixture for high-quality exothermic gas generation.
