The construction involves the installation of the following functional blocks (depending on the technical specifications):

  • Sample transport unit. Used for transporting samples to the analyzer (DGS) in a constant quantitative and qualitative state.
  • Sample reduction unit. It used to reduce the sample pressure to the value required for measurement.
  • Sample cleaning unit. Used to clean the sample from the mechanical and aerosol inclusions. In some cases, may be used for absorption filters remove corrosive substances or substances which could compromise the analysis.
  • The cooling unit. It serves to cool the hot sample to the temperature required for the measurement and discharge of condensed water.
  • Air conditioner (for execution in the closet). It used for heating or cooling the air inside the cabinet. It maintains the temperature inside the cabinet at +10 ... + 20 ° C (at an ambient temperature of -60 to + 50C).
  • The analyzer security module. It serves to prevent sample flow analysis on high-pressurized and / or high temperature.
  • Gas analyzer DHS Eris 200 series. For measuring the concentration of substances in the sample.
  • Sample ejection module. Serves for tap (into the surrounding atmosphere / a candle / refund process) after the sample analysis.
  • The sample flow control unit. It serves to prevent incorrect measurements in the absence of sample flow.
  • The unit of electrical connections. It serves for the electrical connection equipment.

Field of application (short list):

  • air separation stations. Control of oxygen in inert environments.
  • Steaming machines and containers. Control of the oxygen concentration (3-8%) in the vapor medium at the deactivation pyrophoric deposits.
  • The suction line of compressors operating under discharge. Control of the oxygen content in the fuel gas in the suction lines; inert gas supply in case of excess concentrations.
  • Transportation and desensitization solid combustible materials with inert gases. Control of the oxygen content.
  • The use of inert gases to displace combustible gases and vapors.
  • Control of the oxygen content in the columns operating under negative pressure, which draws a substance capable of forming with the oxygen in the air explosive mixtures.
