NOTE:
The following procedures refer only to the use of the BioFlo 4500
equipped with the ML-6100 controller .
There are four high watt density cartridge heaters at the bottom of the vessel. Water is
heated by the cartridge heaters in the jacket, where heat is transferred through to the
media in the inner vessel. Cooling water is admitted to the jacket through the
temperature control valve and the flow control valve.
Vessel temperature control during the growth cycle is controlled from 5
°
C above the
coolant supply temperature to a maximum of 85
°
C. An RTD temperature sensor and
thermowell are provided as standard. The RTD probe provides the signal for a PID loop
capable of holding the vessel temperature to within
±
0.2
°
C. Temperature control and
setpoints are controlled at the touchscreen interface of the ML-6100 if applicable.
The temperature control loop is configured as shown on the following page.
