Bioreactor Gas Panels and Exhaust Condensers: The Lungs of Every Fermenter

At a glance. A bioreactor breathes through two sub-assemblies: a gas panel that feeds air, oxygen, nitrogen and carbon dioxide at controlled flows, and an exhaust condenser that dries the gas leaving the vessel. The Tech Inc. Bioreactor Gas Panel and Exhaust Condenser supplies both, built and tested before it reaches the bioreactor maker or the plant. For biotech, vaccine and pharma plants it is one of the best upgrades a fermentation line can get.

How it works

Each gas line has a filter, regulator, gauge, solenoid valve and mass flow controller.
Gases go to a sparger outlet under the culture and a headspace overlay outlet above it, each through a sterile filter.
The exhaust condenser cools the exhaust gas and returns condensate to the vessel.
A heated exhaust filter stays dry, so it does not blind and stop the vessel breathing.

Versions

Version	Use
Two-gas panel	Air and oxygen for microbial fermentation
Four-gas panel	Air, oxygen, nitrogen and carbon dioxide for cell culture
Panel with exhaust set	Gas panel, condenser and exhaust filter together
Retrofit panel	Replaces the gas train on an existing vessel

Why it is one of the best things to happen to a fermentation line

Precise gassing. Mass flow control on every line keeps dissolved oxygen and pH where the process needs them.
Dry exhaust filters. The condenser and heater stop filters blinding during long runs.
Ready to fit. Built to the bioreactor maker's connections and control signals.
Gas panel experience. Built by the team that makes our gas panels and pressure-reducing stations.

Where it is used

Cell culture and microbial bioreactors, vaccine and biologics plants, research and pilot fermentation, and bioreactor makers who buy gas trains as standard sub-assemblies.
