Field of application

Cleanfit COA451 is a retractable assembly for all fields of dissolved oxygen measurements. It is equipped with a stop bolt, O-ring seals and a ball valve, enabling complete isolation of process and sensor compartment. This allows you to access the sensor without interrupting the process or emptying the pipe or tank. Better still, benefit from increased process and operational safety and significantly reduced maintenance effort across the whole measuring point.

Cleanfit COA451 is a retractable assembly for oxygen sensors with a diameter of 40mm in:

  • Wastewater treatment plants:
    - O2 control in the aeration basin
    - Process water treatment and monitoring

  • Water works:
    - Status monitoring of drinking water
    - Water quality monitoring in rivers, lakes or seas

  • Utilities of all industries:
    - O2 control in the biological treatment
    - Process water treatment and monitoring

  • Fish farming:
    - O2 control for optimum growth conditions

Benefits

  • One assembly for all applications: The 'one for all' principle optimizes stockholding, speeds up project handling and simplifies life cycle management.

  • Easy and safe maintenance: Sensor service and cleaning without process interruption.

  • Robust design: Process pressure up to 10 bar (145 psi), manual operation up to 2 bar (29 psi).

  • Convenient and time-saving operation: Rinse-water connection allows cleaning without removing the sensor from the process.
