Auxiliary equipment

Temperature control systems, vacuum pumps, others

Utilities such as temperature control systems, TCU’s, circulators, chillers, vacuum pumps and others are required to run chemical reactors. Buchi and local Buchi representatives support customers worldwide on the supply of complete chemical process systems with the expertise on reactors and auxiliary equipment.

Temperature control of chemical reactors

Jacketed reactors can be temperature controlled by

  • individual TCUs
  • large central units with secondary systems for individual temperature control
  • steam in case of metal reactors

Jacketed glass reactors require a low circulation pressure in the jacket. This circulation pressure of the heat transfer oil can be controlled by TCU’s shown. Heat transfer oil is pumped through the reactor jacket for heating and cooling. This oil can range from -80°C up to 300°C (depending on the heat transfer oil used) which in turn will control the process temperature inside the reactor.

We cooperate with manufacturers of Temperature control units to supply complete packages - Reactor systems including temperature control units.

TCUs installed outside of the Ex zone, connected to reactors inside Ex Zone 1 or 2, require an additional isolation barrier.
