  • INDUSTRY

    SECURITY WHERE STRONG CURRENTS FLOW
    The industrial life is rough. In metallurgical, steel and rolling mills, refineries, cement and lime plants, or in the oil or gas industry, electrical components are often subjected to extreme stress. Therefore, we guarantee a solid design and robust processing of components as well as ease of access for installation and service from the word go. The modular construction of our switching gear reduces engineering and manufacturing complexity and provides flexibility for different tasks.

    Use JANSSEN energy technology for the efficient and safe distribution of electric current. Worldwide - wherever strong currents flow.

  • POWER PLANTS

    Complete electrical installations from JANSSEN in hundreds of power plants guarantees smooth operation. In lignite or hard coal, pumped storage and gas turbine power plants, as well as in biomass and hydroelectric power plants, and nuclear power plants. Everywhere it is used, our technology ensures that energy is produced and used safely. In addition, it both reduces pollutants and regulates their environmentally sound recycling.

    • System integration of control levels and plant operation
    • Electrical installation and wiring
    • System and process commissioning for entire systems, personnel training
    • Remote maintenance and tele-service.
  • ENVIRONMENTAL ENGINEERING

    REDUCING EMISSIONS AND PROTECTION FROM IMMISSIONS.
    The JANSSEN group is involved with technical and technological aspects of environmental engineering, including the development and use of special procedures to safeguard and protect the environment, as well as restoring previously damaged ecosystems.

    • Disposal (i.e. waste disposal, waste treatment, recycling, construction of landfills, and waste water treatment)
    • Electrical and technical measurement and control of contaminants and remediation of environmental damage
    • Technical measurements for water pollution, noise, and radiation protection, and methods for reducing air pollution (flue gas de-sulfurisation, exhaust gas purification, de-dusting).
    • Development and installation of electrical engineering concepts for the effective use of renewable energy (solar / geothermal / biofuels).
    • Concepts and technical guidance for environmentally friendly production, energy savings, and avoiding or reducing emissions, imissions and waste.
  • HYDRO-ENGINEERING

    CREATE POWER WITH WATER.
    From cleaning to distribution, we offer important support for the water cycle.
