Serial Gas Mixers – beyond standards

LT GASETECHNIK manufactures and supplies standardized serial gas mixers for flammable or non-flammable, corrosive or toxic gases, including associated technical control and analysis technology.

Serial Gas Mixer Serial Gas Mixers









LT Serial Gas Mixer are available for

  • 2 or 3 gases
  • Performance range 15-1000 Nm³/h
  • Inlet pressure 12-25 barg
  • Output pressure 2-9 barg

2. Typical fields of application for Serial Gas Mixers:

  • Shield gas for the welding technology (e.g. Ar/CO2)
  • Protective gas for the food industry (e.g. N2/CO2)
  • Reaction gas for forging technology (e.g. Ar/O2/H2)
  • Forming gas for steel- and rolling mills (e.g. N2/H2 and N2/H2/H2O)
  • Forming gas (HNx) for the glass production (e.g. N2/H2)

4. Features

Our Serial Gas Mixers convince through:


  • High accuracy and repeatability of the gas mixture quality ± 0.5%
  • Reliability
  • Integrated compensation of significant inlet pressure differences (≥ 3 bar), because in every gas inlet line one LTD 1 dome loaded pressure regulator homogenizes the gas pressures.
  • Design according to customer requirements


  • Quality fittings and gas pipes
  • Cryogenic metallic materials (fault protection)
  • Proven interlocking and security concept

Technical features

  • Customized metering (accuracy)
  • High-quality, customized and easy-to-read flow meter
  • Bypass: Precise analysis independent from the buffered gas mixture
  • Blow-off pipe: Set up even without a connected consumer
  • Gas filters in the gas supply lines
  • Extremely low pressure loss
  • Robust, designed for continuous use – more than 20 years of operation are usual
