Endothermic Gas Generators
Advanced control and modular performance in one reliable platform

The AFC-Holcroft EZ® Generator is engineered for efficient, expandable operation with unmatched atmosphere stability. Intelligent automation manages ratio, dew point, and pressure to deliver endo gas of consistent quality while minimizing maintenance and operator involvement.

Additional technical features

  • Modular design: up to three generator modules (1,800 – 13,500 CFH total capacity)

  • Single vertical retort with hinged door for simplified maintenance

  • 6:1 turndown ratio or better for wide process flexibility

  • Automatic air/gas ratio and header pressure control via VFD blower

  • Built-in chart recorder trending endo flow, ratio, dew point, and temperature

  • Auto-correct “bump” logic maintains precise dew point control without operator input

  • Advanced HMI with multilingual support, touchscreen interface, and on-screen manual

  • Integrated burnout cycle automation and catalyst management

  • Ceramic fiber insulation (12 in / 305 mm thick) for energy efficiency and low outlet temperatures
