03 VESSEL TYPES

From bench trials to a 200 m3 train

The organism, product, oxygen demand, shear sensitivity and validation route determine the vessel type and the supporting skid package.

Bench & pilot fermenter

5 L-300 L vessels for process development, media studies and pilot campaigns. SIP-ready options, sanitary sampling and scalable instrumentation.

Seed fermenter

Seed trains from laboratory scale to production inoculation, with controlled transfer, sterile air and repeatable batch records.

Production stirred tank

1 m3-200 m3 microbial production fermenters sized on oxygen demand, broth rheology, kLa and heat load.

Cell culture bioreactor

Low-shear agitation, gentle sparging, tight temperature control and cleanable sterile boundaries for mammalian or insect cells.

Airlift & bubble column

Low-shear gas-driven circulation for selected organisms, products and cell-culture duties where mechanical agitation is not preferred.

Media, buffer & CIP/SIP skids

Supporting vessels, preparation tanks and utility skids for media, buffer, cleaning and steam-in-place sequences.

04 STERILE DESIGN

A bioreactor is a pressure vessel with one extra requirement: nothing gets in

Every penetration through the sterile boundary is treated as a process decision. We define the boundary, the SIP cycle, the cleanability and the documentation before fabrication.

Sterile boundary

A bioreactor is a pressure vessel with one extra requirement: nothing gets in. SIP coverage, drainability, slope, sanitary dead-leg control and sterile air protection are designed as one boundary.

SIP 121-134 C

Condensate drains from every low point, lines slope at least 1:100, and the vessel holds positive pressure with sterile air after cooling.

Hygienic details

316L contact surfaces, orbital or automatic welding, Ra <= 0.4 um finish, sanitary fittings and passivation records support repeatable cleaning.

05 PROCESS CALCULATION

Oxygen is what actually limits your batch

We calculate from your real process data rather than quoting a motor and impeller from vessel volume alone.

Oxygen transfer

Oxygen is what actually limits your batch. We size the vessel and sparger from OUR, broth viscosity, gas rate, kLa and the DO set point.

Impeller selection

Rushton, pitched-blade, hydrofoil, marine and custom impellers are selected for the organism, shear envelope, power per volume and mixing time.

Bubble size

Sparger geometry and gas velocity set the interfacial area. We check dispersion, flooding, foam and gas hold-up before quotation.

Heat removal

Fermentation makes heat. Jacket area, utility flow, insulation and the expected metabolic load are checked against the batch profile.

Required inputs: working volume, peak OUR or DO demand, broth viscosity, organism or cell type, aeration, agitation, feeding strategy, target temperature and sterilisation cycle.

06 ENGINEERING RANGE

Bioreactor size chart

Final dimensions, motor rating and instrumentation are calculated from your process data and validated against the approved URS and P&ID.

Scale	Working volume	Typical duty	Agitation / control
Bench	5-30 L	Organism screening and media studies	Small impeller, pH / DO / temperature
Pilot	50-300 L	Scale-up and pilot campaigns	SIP, sterile air, kLa study
Seed	0.3-5 m3	Inoculum train and transfer	Controlled agitation, SIP, transfer panel
Production	5-200 m3	Microbial or cell-culture production	PLC / HMI, recipe, batch records, IQ/OQ

07 CONTROL SYSTEM

The loops that keep a batch on trajectory

Siemens or Mitsubishi PLC with HMI or SCADA, closed loops for temperature, pH, dissolved oxygen, agitation, vessel pressure and air flow. Probes from Mettler Toledo, Hamilton or your existing brand can be specified.

Temperature

Product temperature, jacket utility flow, heat load and alarm limits.

pH

Probe, acid / base dosing, calibration and recipe control.

Dissolved oxygen

DO cascade through agitation, airflow, oxygen enrichment and back pressure.

Pressure & airflow

Vessel pressure, sterile air by mass flow controller, exhaust and filter integrity.

Foam & level

Foam probe, antifoam dosing, level indication and high-level protection.

Batch records

Trends, audit trail, recipes, alarms, OPC UA and validation-ready reports.

08 FABRICATION

How a hygienic vessel is actually built

Inspection hold points keep material, welding, finish, control and test records traceable from plate intake to FAT.

Plate & component intake

316L heat numbers, thickness, fittings, valves, instruments and certificates are checked before release.

Laser cutting & forming

Shell, heads, openings and jackets are formed to the approved GA drawing and tolerances.

Orbital & automatic welding

Qualified procedures, controlled heat input, weld maps and traceable operators protect the sterile boundary.

Jacket laser welding

Heating and cooling channels are welded to the calculated pattern and independently tested.

Weld examination

Visual, penetrant, radiographic or borescope examination follows the inspection plan.

Polishing & passivation

Product-contact surfaces are polished, cleaned and passivated to the specified roughness.

Assembly & pressure test

Agitator, probes, valves, filters and panels are assembled before vessel and jacket testing.

FAT with water

Pressure, leak, control, mixing time, kLa, sterility hold and documentation checks are completed before shipping.

11 BUYER QUESTIONS

Bioreactor FAQ

What is the difference between a fermenter and a bioreactor?

Both are vessels for biological processes. A bioreactor is built for tightly controlled microbial or cell culture work, with sterilization, sensors and kLa-sized agitation. A fermenter is often simpler. Working volumes range from 5 L to 200 m³. Tell us your organism and process.

How is the vessel sterilized (SIP) and what utilities does that need?

Vessels are designed for steam-in-place sterilization at about 121–134°C, so you need clean steam, condensate removal, cooling water and compressed air. We confirm utilities from your process.

Which sensors and control loops come as standard?

Typical loops control temperature, pH, dissolved oxygen, pressure, level and foam. The exact list depends on your process and is defined in the quotation.

What materials and finish do you use?

Product contact is 316L stainless steel with a polished interior, laser-welded jackets and passivation. Traceable materials are supplied.

What GMP documentation can you provide?

We can provide IQ/OQ documentation, material certificates, weld and test records and factory acceptance documents. Requirements depend on your regulator, so tell us your standard.

How do you check mass transfer before shipment?

Agitation and aeration are sized from kLa, and tests are performed to agreed methods. Acceptance criteria are defined in the project documents.
