ZETA bioreactors are engineered around process requirements – not standard vessel templates. Critical performance parameters such as oxygen transfer rate (kLa), mixing time, power input, and heat transfer are evaluated during design to ensure predictable scale-up and stable production. Our fabrication network supports these engineered designs with full material traceability, ASME-compliant construction, and documentation packages prepared for qualification.

Each system is designed to support:

Reliable agitation and mass transfer

CIP/SIP integration

Thermal control under varying loads

Seamless integration with plant automation

Designed for development to commercial scale. From pilot validation to full production capacity.

ZETA bioreactors support the complete scale-up pathway – from development and pilot phases through commercial manufacturing. These systems are not treated as standalone tanks, but as engineered process units – integrated into automation architecture, utilities, and facility layout from the earliest design phase.

These systems integrate seamlessly into:

Standalone upstream skids

Multi-skid modular platforms

Fully automated production suites

Typical Applications

Upstream Fermentation & Cell Culture

Seed fermenters, production fermenters, and cell culture reactors for microbial and mammalian systems.

Process Support Vessels

Harvest tanks, buffer hold vessels, CIP return vessels, and media preparation systems.

Flexible Production Modes

Batch, fed-batch, and perfusion configurations engineered for control and repeatability.

Application Areas

Monoclonal antibodies (mAbs), recombinant proteins, vaccines, plasma derivatives, and cell & gene therapies.

Engineered for fermentation and cell culture.

Bioreactor requirements vary significantly between mammalian cell culture and microbial fermentation processes. ZETA designs fermenters and bioreactors to accommodate the full spectrum of upstream production needs. This capability allows ZETA bioreactors and fermenters to support a wide range of upstream manufacturing strategies across biotechnology and pharmaceutical production.

Microbial Fermentation

Cell Culture Fermentation

For microbial fermentation, reactors are designed to support:

• High oxygen transfer rates (OTR)
• High power input agitation for dense cultures
• Efficient gas dispersion and aeration control
• Robust cooling capacity for heat-intensive fermentation
• Foam control and process stability at scale

For mammalian cell culture, systems are optimized for:

• Gentle mixing and low shear environments
• Controlled gas transfer for sensitive cells
• Stable perfusion and fed-batch operations
• Consistent process conditions across scale-up

Risk-reducing engineering.

First-time-right design backed by data.

ZETA combines bioreactor design with simulation and characterization expertise to reduce scale-up risk and prevent costly rework. Computational Fluid Dynamics (CFD) and performance modeling can be applied during design to validate mixing performance and eliminate blind spots before fabrication begins.

Where required, bioreactor characterization studies can support:
• Agitation optimization
• Gas transfer validation
• Shear assessment
• Heat removal capacity confirmation

This engineering-led approach ensures performance is verified – not assumed.
