        3. Color LCD Integrated Microprocessor Controller system
        4. Validation support documentation available(IQ,OQ)
        5. Fermentor system represents ideal intermediate step for scaling up
        6. Automatic control and data saving of DO, pH, temperature agitation
            and nutrient feed for fermentation process.
        7. Processing parameter are controlled by microprocessor controller.
        8. Automate or Manual sterilization in place by external steam supply
            or optional steam generator.
        9. The modular design consists of the supply unit the culture vessel
            and the control cabinet.
        10. The open frame design of the supply unit provides ready access
              and ease of maintenance and operation.

Microprocessor based PID




Using 316L stainless steel it is polished mechanically or electrically


316L stainless steel prevent contamination and is polished by electrically


Viton or silicon material is used for the O-ring and the EPDM is used for gasket


Built-in heater makers the in-situ sterilization for the vessel, head plate, filter, aeration pipe lines in 105℃~130 temperature range automatically



From 3oC above the cooling water temperature to 80oC (accuracy ±0.1 )




The built-in heater cartridge raises and cooling water pulling downs the water temperature and water pump circulates the water inside of the jacket

Data Storage

pH, DO, Pressure, Temperature and Agitation speed


  • Stainless steel (SUS 316L) is used to prevent contamination and rust.
  • Water jacket system is adopted for precise temperature control.
  • 6~8 toggle bolts make it easy to assemble and dissemble the head plate.
  • Sight glass makes to monitor the status of the media.
  • Spare ports are installed on the head plate that the auxiliary sensor can be installed.
  • Sensor ports are installed in the circumferential direction on the lower side of the vessel
