Friborator - Model TRG - Gas/Liquid Mixing Turbines with Pressure Support

For many large-volume production procedures in chemistry or biotechnology when using aerobic micro-organisms, the economic efficiency calculation shows the energy consumption of the reactor agitators as an important post, as well as the costs of the raw material. And this is exactly where we focus our TRG technology offerings. Excellent gas transfer rates with comparably small drive capacities for primary pressure-supported TRG turbines and the respective compressor unit characterise TRG technology. No dynamic agitator or static gas introduction system known to us has a similar efficiency (kg_Gas/kWh or kmol_Gas/kWh) with comparable installation costs. 

Comment:
The drive capacities for the TRG ventilation units in aerobic fermentation are normally only between 1 and 2 kW/m³, depending on the working volumes of the industrial bioreactor. With these capacities, oxygen transfer rates of 4 - 8 kgO₂/m³/h can then be achieved. However, our portfolio also includes extensive ventilation systems and systems with considerably higher specific energy transfers
