Temperature control units (TCU) used with jacketed reactors
TCUs are used for accurate temperature control in combination with jacketed reactors. By circulating a heat transfer oil through the reactors jacket, efficient heating and cooling of the process media as well as stable process temperature is achieved. Temperature control with TCUs is used for chemical reactors made of glass, glass lined steel, but also made of stainless steel, Hastelloy and other metals.
TCUs installed outside of the Ex zone, connected to reactors inside Ex Zone 1 or 2, require an additional Buchi isolation barrier. For large TCUs, see also glass equipment, auxiliary equipment.
Chemical reactors can be operated by TUCs with heat transfer oils of different temperature ranges from -80°C up to 300°C - info on request. Typical operation temperature: -50 °C to +250 °C
