Three gas mixer type advanced

Industry 4.0 solution

Reliable provision and complete documentation of defined gas mixtures for your production with high-tech gas mixers suitable for Industry 4.0:

  • Convenient and intuitive operation via touch screen, connection to higher-level systems possible thanks to fully automatic control and fully automatic operation
  • Bidirectional data exchange with higher-level systems (e.g. oven control, process control system, etc.) Interfaces: Ethernet, Modbus TCP/IP, Profibus, CANopen
  • Very precise gas mixing: 0.2% guaranteed repeatability
  • Gas analyzer included: Reliable measurement precision
    Extractive continuous concentration determination of flammable or non-flammable gas components in gas mixtures
  • Integrated data logger for documentation of inlet pressures, gas flow rates, gas analysis results.
    Internal data recording, data can be transferred for evaluation via interface on the front of the housing
  • No additional software required

Static gas mixers

(smart or comfort types)

Gas mixture setting

Static gas mixer:
Manual setting via dosing valves, with manual data reading via pressure gauges and flow meters


+/- 0,5%

Achieving exactly the same gas mixture after changing the gas mixture setting

Accurate reproduction is not possible without a gas analyzer due to parallax errors and different metering valve settings with different thread flank stops.

Documentation of the gas mixture

Possible with manual writing, which is subject to parallax errors

Special features

  • durable
  • Safe
  • Easy to maintain

Dynamic gas mixers

(type advanced)

Gas mixture setting

Setting electronically, reproducible via local control unit additionally data transfer from a central control system. Automatic compensation of pressure and temperature changes


+/- 0,2%

Achieving exactly the same gas mixture after changing the gas mixture setting

Exact reproduction using electronically adjustable values.

Documentation of the gas mixture

Fully automatic documentation of the mass flows of the individual gases. Transfer of data via USB or PLS interface for evaluation e.g. through Excel.

Special features

  • Adjustable on the integrated touch screen -> Convenient and user-friendly
  • Comprehensive documentation of the individual values -> Quality assurance
  • Remote controllable -> Integration in higher-level control system possible
  • High accuracy -> Best gas mixing results
  • Further options -> Expandable

* Reproducibility is defined as the repeatability deviation of the individual measurement from the respective reference measured value for the gas mixers offered here. This requires operation within the design limits, approximate temperature uniformity of the gases, constant pressures, as well as professional maintenance and servicing in accordance with the technical rules and manufacturer’s instructions.

What both gas mixer concepts have in common is that the extraction can also be switched on and off remotely via a solenoid valve.

Your specification, our solutions – Advanced gas mixer

  • Supplied gas mixers from
    a few l/min up to 10,000 Nm³/h
  • Redundant versions with fully automatic bumpless switching
  • Gas mixer for 2 to 20 gases for
    • Toxic and poisonous gases
    • Flammable and non-flammable gases
    • corrosive gases

And of course we also take care of commissioning, training, service and maintenance!

Advantages of the LT gas mixer Advanced

Convenient Industry 4.0-compatible and precise gas mixers:

  • Simple operation on site via touch screen or from the higher-level process control system. The gas mixer follows the specifications automatically
  • Even without a higher-level DCS, full automated functionality via on-site operation
  • Automatic restart after standstill
  • No manual intervention for product changeovers; entering the new setpoint leads to automatic adjustment of the desired gas mixture
  • Only a dynamic (= fully automated) design with MFC ensures that the gas mixture quality continuously and precisely corresponds to the setpoint values set in each case

Tried and tested design: Reliable, durable and easy to maintain

  • Technically tight in the long run
  • High-quality and reliable valves and components for demanding production environments
  • Rugged design, resistant to environmental influences
  • Easy accessibility and maintenance
