  • Model PreMix 2000
    PreMix 2000 Analyzer

    Forehearth zone temperature is critical to proper flow of molten glass to fiber forming equipment. The combustion atmosphere in fiber forming baskets is equally important to ensure fiber quality and consistancy. Forehearth zone temperature and fiber forming atmosphere are both controlled by adjusting the air to fuel ratio of discrete premix burner stations feeding these systems. Continuous analysis of resultant excess oxygen or excess fuel from air to fuel ratio adjustments is needed to automate the glass fiber manufacturing process.

  • THERMOX  Model WDG 1200 Insitu
    WDG 1200 & 1210 Insitu

    The WDG 1200 Insitu and the WDG 1210 Insitu are rugged, reliable flue gas analyzers for net oxygen that use industry-proven zirconium oxide sensor technology. The outer probe tube is 310 stainless steel so no abrasion shield is needed for most applications. The controller features precision temperature control for optimum stability, built-in diagnostics, and over-temperature protection. Modbus and 4-20 mA outputs are standard; automatic calibration is available. The unique sensor design allows the entire sensor assembly, including the heater, to be removed without disturbing the outer protection tube which remains in the process. This makes field service fast and easy, and because there is no need to return the probe to the factory for repair, there’s no expensive downtime.

  • Model WDG Insitu Probe
    WDG Insitu Probe

    Modern gas, oil and coal fired boiler operations require dependable, low-maintanence, application flexible devices to monitor and control combustion processes. The measurement of excess oxygen in flue gas is particularly important for obtaining maximum combustion fuel efficiency while minimizing thermal or fuel-bound Nitrogen oxides generation. The zirconium oxide insitu probe has become the industry standard for making this flue gas-oxygen measurement. However, most insitu probe designs do not afford ideal accessibility to filter, cell and heater components, requiring removal of the probe from the process flange for servicing.

    WDG-IV UOP/RP Analyzer

    The UOP Continuous Catalyst Regeneration Process requires low-level continuous oxygen measurement during the regeneration process to protect the Platonized catalyst from oxidation. The process is operated at elevated temperature and pressure. The flue gas contains low levels of HCL and catalyst fines. The critical oxygen measurement analyzer must be able to survive the veracious nature of the process while maintaining a high level of accuracy at low level oxygen concentrations.
