  • Ports: Ports designed according to user requirements
  • Piping and Valve Materials:

Parts that come in direct contact with the product / medium uses SUS-316L EP (≤20 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

E.) Constructed with SUS304 stainless steel



  • Uses (at least) 12” color touch screen
  • User-friendly, graphical control interface
  • Includes secure user accounts, with different levels of access
  • Use stainless-steel controller cabinet
  • 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 a power outage/interruption. When power is restored, the interrupted process will automatically resumed.
