FAQ Heat Exchanger

[+] What properties does a heat exchanger made of graphite have?

  • High thermal shock resistance
  • Excellent thermal conductivity
  • High mechanical compressive strength
  • Operating temperatures of maximum 180°C up to 200 ° C, with PTFE impregnation up to 230°C.

[+] For which applications graphite block heat exchanger to be used?

These heat exchangers are used for aggressive media, because graphite has very high chemical resistance.

[+] Which designs and materials are available?

The thermal plates are available in two versions: as a simplex or duplex cushion profile. These options are delivered in almost every shape and size made of stainless steel, nickel and special alloys such as Hastelloy or titanium.

[+] What kind of applications are thermal plates suitable for?

Due to the efficient heat transfer, the thermal plates are suitable for heating or cooling of containers or liquids (direct immersion).

[+] What are thermal plates used for?

  • Immersion in liquid applications
  • Coating of containers
  • Thermal plates as containers

[+] Can heat exchangers with mixing elements be used anywhere?

Basically, yes. However, this investment makes sense only for applications used for tempering of viscous media, for which plate heat exchangers, etc. are not suitable. Whether pharmaceutical, chemical or food industry – the design (removable or fixed integrated mixing elements) is always configured depending on the application.

[+] Why heat exchangers for viscous media are equipped with mixing elements?

During tempering of viscous media, the product area tubes tend to cake. To minimize and prevent the so-called fouling and to improve the heat transfer, mixing elements are used.

Thus, the product which flows laminar is continuously shifted from the centre of the pipe to the pipe wall and vice versa. As a consequence, the time intervals between downtimes for cleaning the the product area tubes and the construction size / length of the heat exchanger can be reduced as compared with the heat exchangers with no mixing elements.
