Purpose-built for bioprocess performance. Engineering control at every operating condition.

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.

Where sterile operation is required, vessel geometry, product-contact surfaces, agitation, instrumentation and transfer connections are engineered to support aseptic processing and validated CIP/SIP cycles.

Each system is designed to support:

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

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
• Closed, aseptic operation for contamination-sensitive cell culture processes
• Sterile media addition, sampling and harvest interfaces

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.
