Temperature Control

About TCUs

Depending on your application, our chemical reactors may require temperature control:

  • Jacketed metal reactors can be operated by steam or oil
  • Jacketed glass reactors require a low circulation pressure within the jacket which can be controlled by TCUs

TCUs circulate heat transfer oil through the reactor jacket, which can be heated and cooled. Depending on the heat transfer oil, the TCUs can keep process temperatures inside the reactor between -80°C and 300°C.

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

We cooperate with temperature control unit manufacturers to supply complete packages - reactor systems including temperature control units.


Please do not hesitate to contact one of our Sales Engineers at Buchiglas USA Corp. for a specific TCU quote.
