Endogas Generators

The Almor Wild Barfield Endothermic Gas Generator is based on the well proven Wild Barfield design and is used for the production of a high quality protective gas. Endothermic gas is produced by passing a sub stoichiometric mixture of a hydrocarbon (natural gas, propane etc.) and air through a heated retort, containing a nickel impregnated catalyst.

Design Features

  • Output 15m³/hr to 180m³/hr
  • Modular construction for up rating to higher capacity
  • Electrically or Gas heated
  • Multi-tube catalyst retorts for optimum ‘cracking’ (EN120 – EN180)
  • Better than 5:1 automatic turn down
  • Natural convection air cooling (no water or electric)
  • Fully automatic operation
  • PLC control with HMI for control and datalogging
  • Range of gas quality control devices (dewpoint, CO2)
  • Conforms to BS EN 746:3

Generated carrier gas gives the best controllability, reproducibility and high quality end product, compared with alternative methods of controlled atmosphere production (i.e. nitrogen/methanol, ‘in furnace’ generation) and can be used in a wide variety of heat treatment processes including:-

    • Gas carburising (+ hydrocarbon)
    • Gas carbonitriding (+ hydrocarbon + ammonia)
    • Neutral hardening (+ hydrocarbon)
    • Gas nitrocarburising (+ ammonia)
