  • Page 24: Cooling Water System

    Components of the System and Their Role 4.2.8 Cooling Water System The cooling water has the task of absorbing and dissipating the heat produced during ozone generation in the chamber of the ozone generator (1-2). This heat dissipation is important in order to keep the ozoniferous gas at a low temperature to maintain the excellent ozone output and to protect the internal components of the ozone generator.

  • Page 25: Safety Equipment

    Components of the System and Their Role 4.2.9.2 Electronic Power Units Every electronic power unit (1-20) supplies a HV transformer (1-21) with medium frequency alternating voltage. The HV transformer (1-21) generates the alternating high voltage needed for the ozone generation process from this voltage. The medium frequency tech‐ nology provides significant advantages over the mains frequency conventionally used in ozone generation.

Fatal injury by electrocution The system produces high voltage. – For safety reasons, only allow appropriately qualified technical personnel to install, operate and service this system. – Ensure that all technical personnel are trained by the manufacturer about the specific system.
  • Page 35 Assembly and installation The room in which the system is installed must be monitored by an ozone warning device, which switches off the plant in the event of a leakage of ozone. The gas detector must provide a visual and acoustic warning. The ozone sensor should be installed where the highest concentration of ozone is to be expected in the event of an accident.

  • Page 37: Ozone Removal From Filters And Reaction Section

    Assembly and installation CAUTION! It is imperative that a non-return valve is fitted directly at the point of injection for the correct and proper operation of the ozone generation system. The pressure drop through the valve with a nom‐ inal gas flow rate must be low (< 0.1 bar), and the valve may only be manufactured from ozone- resistant materials.

  • Page 38: Assembly

    Assembly and installation CAUTION! If the correct and proper functioning of the removal system in the filters or reaction vessels cannot be guaranteed, there is a risk that ozoniferous water may inadvertently pass through the system to the discharge point. Service and maintenance to comply with regulations is thus important.

  • Page 47: Adjusting The Initial Gas Pressure

    Commissioning CAUTION! – During commissioning, the personnel respon‐ sible for the OZMa ozone generation system must be instructed on the operation of the system, as well as on its measuring technology (calibration of sensors etc.). They must also be trained in all safety-related issues.

  • Page 48: Adjusting The Cooling Water Flow Rate

    Commissioning The "gas flow rate" is displayed on the touch panel. Once the operating gas flow rate has been set, ensure that the adjustable operating gas throttle valve (1-4) is firmly fixed using the appropriate locking nut. A gas flow rate below the nominal flow rate results in a higher concentration of ozone and lower ozone emissions from the system.
