Compact gas mixer with stainless steel housing for the production of individually adjustable gas mixtures of two gases


The iMixproVarioX gas mixer operates according to the diffusion mixing principle. It has an integrated constant pressure regulation and features an auto-stop function stopping the production of the gas mixture when the gas supply is interrupted.

The iMixproVario gas mixer is equipped with inlet and outlet pressure regulators for setting the required inlet pressure of the gas mixture. The adjusted pressures are indicated by the integrated pressure gauges.

The iMixproVarioX is perfectly complemented by the mobile gas analyser GA300 for monitoring the set gas mixture based on the thermal conductivity measurement principle.


  • For one individually adjustable gas mixture (within the technical limits)
  • Withdrawal of mixed gas up to maximum capacity of 31,5 m3/h, 42 m3/h or 63 m3/h (depending on product version and pressure ratio)
  • High mixing accuracy even in case of gas withdrawal variations and without additional power supply
  • Integrated inlet pressure regulator and mixture outlet pressure regulator
  • Cost savings due to the avoidance of storage of different premixes
  • Diffusion-mixing principle, no power supply or additional buffer vessel required
  • Prepared for wall mounting


  • Simple mixture adjustment by turning the handwheel
  • Adjustment of the inlet pressures and the gas mixture outlet pressure and their indication by pressure gauge


  • Does not depend on input pressure differences due to integrated constant pressure regulation
  • Does not depend on gas withdrawal variations
  • Mixture production stops automatically when gas supply is interrupted
