For many years, FRINGS has been providing gas/liquid reaction technology to the chemical, biotechnology and food processing industries. We offer our application engineering, reactors and customized equipment based upon practical experience.
Rotor-stator aerators for process technology
The core component of our high performance mass transfer reactors is the FRINGS rotor-stator aerator FRIBORATOR. It provides:
- Fine-bubble aeration (gas/liquid interphase boundary)
- Free jet mixing
The gas transfer from fine primary bubbles through the gas/liquid interphase boundary into the solution determines the absorption and reaction speed, providing that the reaction is independent from the dissolved gas concentration.
The ingredients of the solution to be aerated, especially salts, alcohols and organic acids, determine the coalescence of the bubbles, the decrease in the number of bubbles and the effective mass transfer area.
