    Tailor made gas mixers for protective gas atmospheres in the food and beverages industry

    To prevent loss of natural freshness and quality, food are often packaged in a protective atmosphere (Modified Atmosphere Packaging – MAP). Using natural gas the quality is maintained and the durability is improved. For this different gas mixtures are needed which can be produced in LT’s gas mixers. I.e..:

    • Raw red meat or raw dark poultry:
      O2 and CO2 (Oxygen and Carbon Dioxide)
    • Raw white meat, cooked meat or sausages:
      COand N2 (Carbon Dioxide and Nitrogen)
    • Raw Fisch:
      CO2, Oand N(Carbon Dioxide , Oxygen and Nitrogen)
    • Smoked fish, boiled fish, crab/shrimp
      COand N(Carbon Dioxide and Nitrogen)
    • Hard cheese, soft cheese, yoghurt
      CO2 and N(Carbon Dioxide and Nitrogen)
    • Vegetables, salads
      O2, CO2 and N2 (Oxygen, Carbon Dioxide and Nitrogen)
    • Beer, Champagne, Sparkling Wines
      COand N(Carbon Dioxide and Nitrogen)

    LT GASETECHNIK’s serial gas mixers for two or three gases for the food industry have a capacity of a few liter per minute (l/min, slm or slpm) to 500 cubic meters per hour (m³/h or scm/h). They are optionally available

    • with or without a buffer vessel
    • with or without gas analyzer
    • as static gas mixer with manual control or
    • as dynamic gas mixer with fully automatic control with MFC (Mass-Flow-Controller)

    Dynamic gas mixers typically display process data, alarms and error messages on a local operator panel and, if desired, are passed to the process control system of the customer.


    Feel free to ask us or request your quotation.

    Project examples

    • MFC-based gas mixer for carbon dioxide and nitrogen (beer gas); capacity: max. 150 m³/h
    • Gas mixers for three gases (N2, CO2, H2)
      for fully automatic test of the tightness of food packaging
    • Gas mixers for N2, CO2, mixing ratio 60% / 40%; Capacity about 125 m³/h


    • Particularly high accuracy and reproducibility
    • Static or dynamic, fully automated systems with cascade ratio control
    • Control, analysis and documentation of results with tailor-made solutions
    • Connection of the equipment to existing plant PLC and / or telemetry
    • High availability incl. remote maintenance
    • Redundant versions: Switching over without pressure peaks
    • Unmatched security: Redundant measurements

    ….just beyond standards
