Piping and valve materials

Parts that directly contact with the product/medium uses 316L stainless steel (≤25 Ra/in) internal polished tubing (BPE standard) :
A.) Internal EP polished diaphragm type pneumatic valve and manual valve (BPE standard)
B.) Tubing all welded with orbital welding
C.) Vessel bottom drain uses a diaphragm valve, to minimize dead volume
D.) Piping designed for ease of transfer to scale up (can be used as a seed fermentation system) or downstream process

Parts that do not directly contact product/medium
A.) Constructed with 304 stainless steel

Controller

10.4” color industrial touch screen

* User-friendly, graphical control interface
* Includes secure user accounts, with different levels of access
* Modularized and standardized design (Module Skid): ergonomically designed according to height, ease of vessel clean
   up,  and ease of extraction in relation to vessel bottom valve
* Includes maintenance page with system diagnostics
* All programmed setting values are automatically stored into the built-in memory; the settings will not be lost in case of power outage/interruption. When power is restored, the interrupted process will automatically resume

Setting

* Automated sterilization process
* Automated fermentation program

DO

pH

Pump

* Built-in peristaltic pumps

* Each feeding pump can run adjustable 15-step program
* Each pump can be adjusted for speed, forward and backward direction, and manual or automatic mode
* Each of the four peristaltic pumps can be designated for different functions: acid pump, base pump, antifoam pump, or 
   substrate feeding pump
* Optional fifth and six peristaltic pump available

Temperature

* Vessel temperature is measured with a side-inserted PT-100 temperature probe and maintained using PID control.
* Control range: 0-130°C, ±0.1°C. Operational range up to 0-60°C

Agitation

* Manual or automatic control of agitation speed
* 15-step program to change speed, or use DO cascade control

Air supply and exhaust

Gas supply and dehumidifer: uses in-house air compressor or air dehumidifier
* Includes re-useable, autoclavable 0.2μm air filter for gas inlet
* Gas Inlet (air)
    Includes mass flow controller:
    2 vvm maximum according to the vessel capacity
* Gas Inlet (oxygen)
   Includes pure oxygen rotameter (manual flow control):
   1 vvm maximum according to the vessel capacity
* Includes oxygen gas solenoid valve, with automatic pulsed time control

Air outlet / Exhaust
* Exhaust port with stainless steel condenser
* Includes re-useable, autoclavable 0.2μm air filter
* Includes automated adjustable gas outlet valve to adjust vessel back pressure
* Can control manually or automatically via software
