Agitator shaft seal (Mechanical & Packing Type)

A critical component of the fermenter stirring system. It provides sealing between the rotating agitator shaft and stationary tank shell. It prevents leakage of process media and fermentation gas, while blocking ingress of ambient air, microorganisms and

Aseptic Sampling Valve

Mounted on fermenter side wall for sterile broth sampling during fermentation. Samples are taken for dissolved‑oxygen, pH and cell‑density testing. It prevents foreign bacterial ingress and avoids cross‑contamination of the entire tank batch.

pH electrode

Core sensor for bio‑fermentation processes, providing real‑time on‑line monitoring of culture‑medium pH value.

Defoamer (paddle & probe)

Device for breaking foam at the fermenter liquid surface. It prevents foam overflow and liquid carry‑over, reduces microbial contamination risk and cuts antifoam consumption.

Sight glass (high temperature resistant)

Allows on‑site visual inspection of fermenter liquid level, foam condition and material mixing.

Tank Bottom Diaphragm Valve

Mounted at the lowest point of fermenter for broth discharge, tank draining and bottom CIP waste removal. Flush‑mounted dead‑zone‑free design prevents material buildup and microbial contamination; compatible with SIP / CIP processes.

Spray Ball (CIP)

Key CIP component for fermenters. It sprays wash liquid to scour tank walls and internals, removing process residues and ensuring cleaning performance.

Dissolved Oxygen Electrode

Provides on‑line measurement of dissolved‑oxygen level in fermenter culture medium to guide adjustment of agitator speed and aeration rate, satisfying microbial oxygen‑supply requirements.

Thermowell

Shields temperature sensors (platinum RTD) from direct contact with fermentation media for accurate temperature measurement.

Respirator filter element

Filter cartridge fitted inside fermenter and storage‑tank breathers. It provides sterile filtration for incoming ambient air and outgoing tank gas, protecting tank contents from microbial contamination.

Jacketed Safety Valve

Over‑pressure protection for fermenter jackets. It automatically relieves pressure when cooling or steam heat‑exchange pressure exceeds limits to avoid jacket deformation and failure.
