Pilot-scale systems

TLM500 pilot bioreactor
TLM500 pilot bioreactor

Pilot scale is the scale-up step before commercial production. Talamus pilot systems run the sterilisation in place (SIP), controlled cooling and cultivation phases automatically. The system integrates with plant utilities (steam, cooling water, compressed air).

TLM120

20 L seed reactor + 100 L pilot reactor

TLM120 is a pilot system with automated phase management, consisting of a seed reactor and a pilot reactor. We deliver both vessels on a shared skid together with valves, instrumentation and the control unit.

  • Sterile transfer from the seed reactor to the pilot reactor
  • Automated sterilisation in place (SIP) and phase control
  • Time-stamped logging of the defined process variables for scale-up studies

TLM500

500 L working volume (600 L total)

The TLM500 photographs on this site show this system.

TLM500 is a jacketed, stirred pilot and pre-production reactor. It operates with plant steam, cooling water and compressed air connections. SIP, controlled cooling and cultivation phases run automatically. Harvest follows steps defined on the control unit.

TLM500 components

Automated SIP, cooling and cultivation phases

The operator selects the process phase; the related valve positions, permissives and control loops engage in a defined sequence.

TtSchematic view; set points are defined in the project documentation.

Plant steam is used for jacket heating, while the product-contact sterilisation in place (SIP) circuit uses steam of a quality suited to the process requirement. Steam distribution, condensate drainage, temperature measurement points, hold time and any required isolation or protection arrangements are defined within the project. SIP conditions are managed within equipment and sensor limits.

  • SIP including the vessel and the inlet and exhaust gas filter lines
  • Automated SIP cycle started from the control unit
  • Sterility maintained on sampling and feed lines

Process instrumentation

  • Analogue or digitally communicating pH measurement chain depending on the selected model, and optical dissolved oxygen sensor
  • Hydrostatic level and vessel pressure measurement
  • 4–20 mA analogue signal or digital communication such as Modbus, depending on the sensor/transmitter model
  • We select instrumentation with calibration, technical service and spare-part availability in mind
  • Process analytical technology (PAT) options: in-line biomass/optical density, viscosity, exhaust gas analysis and dissolved CO₂

Sterilisation and cleaning

  • Automated steam sterilisation in place (SIP) including filter lines; scope defined in the project documentation
  • Cleaning in place (CIP) equipment; chemicals, temperature, flow, duration and return design set per project scope
  • Maintenance access with a lid lifting device

Site conditions defined before installation

We review the plant utility values in the first meeting and define them in the project documentation.

  • Plant steam: availability, pressure and quality
  • Compressed air: flow, pressure and oil-free/dry conditions
  • Cooling water or chiller capacity
  • Water quality, flow and pressure required for process and cleaning
  • Electrical infrastructure and panel location
  • Layout: skid, control unit and service clearances

Technical consultation request

Information on the target batch volume, seed stage and the steam, air and cooling utilities available on site is sufficient for an initial assessment.
