The Büchi TCU is a temperature control unit designed specifically for jacketed reactors in pilot plants and production-scale chemical processes. It provides both heating and cooling functions using heat transfer oil as the working medium.

Principal Operation

• Heating/Cooling Principle: Heat transfer oil is circulated through the reactor's jacket to ensure uniform temperature distribution inside the vessel.
• Temperature Range: The system achieves temperatures from -80°C to 300°C, depending on the selected oil.
• Circulation Control: Jacketed glass reactors require low jacket pressure, which is precisely regulated by the TCU.
