Purification Units for Controlled Atmospheres

Elimination of H2O and/or O2 from Neutral Gases (Ar/N2/He)


JACOMEX systems have unique technical specifications which ensure long-lasting maintenance of purity with regenerations spaced out over time.


  • Substantial gas savings
  • Automatic regeneration (N2-Ar mix.3-10% H2)
  • Stable purity over time without regeneration or maintenance
  • Automatic pressure regulation without vacuum pump (including in use)
  • Silent operation (noise level <50dB)

Shared technical data

  • PLC-controlled purification unit
  • Contrôle de température de l’épurateur
  • Colour touch screen interface: continuous monitoring and recording of functional data
  • Automatic regeneration N2 / Ar / He + H2
  • Leakage rate <10E-5mbar l/s
  • Closed loop circulation
  • Configurable H2O and O2 alarms
  • Configurable automatic gas flushing
  • USB and Ethernet ports: data export and remote control


Gas Purification and Management

Jacomex expertise allows us to answer your specific needs while taking critical parameters into account:


  • Volume, number of gloves, glove box leak rate
  • Internal process, materials and products handled.
  • Application field, research, production
  • Risks analysis and security constraints
  • Running and maintenance costs
