Heating and Cooling Combination Ceramic
General Information
Heating and cooling systems, with or without intensive air cooling, are used to heat or cool metal extrusion cylinders in industrial applications. The process begins by heating the metal cylinder. Once the operating temperature has been reached, the heating output is reduced via a control system, and the frictional heat generated during the production process sometimes provides the necessary temperature.
If the operating temperature is exceeded, the flanged fan is switched on and the extrusion cylinder is cooled down. This ensures optimum temperature control along the entire length of the plasticising cylinder.

In general, individual customer requirements regarding materials, dimensions, electrical parameters and, for example, quick-release fasteners can be accommodated following consultation and clarification of all technical details.
Installation and commissioning
During installation, care must be taken to avoid deformation and excessive spreading of the heating element. Difficult installation conditions should be taken into account at the design stage. The heating elements must only be operated with a suitable temperature control system.
The following points must be observed:
The cooling fins (for intensive air cooling) and the associated heating elements must be fitted with a positive fit around the cylinder surface to be heated. To do this, it is necessary to partially dismantle the heating-cooling combination, which is fully pre-assembled for transport and dispatch. To do this, the upper cooling jacket shell is removed or, depending on the design, opened up so that the clamping screws on the heating bands can be loosened and removed. The transport protection can now be removed. The heating and cooling system, now opened up in this way, is then fitted onto the machine cylinder and lightly secured using the clamping screws on the heating bands. Once the upper cooling jacket shell has been fitted or folded shut, the heating-cooling combination can now be aligned. After opening the upper cooling jacket shell again, the clamping screws on the heating elements are finally tightened (torque 2 to 4 Nm).
Once the upper half of the cooling jacket has been closed, the heating-cooling unit is ready for use without the need to remove the wiring. However, care must always be taken to ensure that no mechanical damage occurs to the metal parts or the wiring. If the connection is not a positive fit, the heating element will be destroyed by overheating.
The heating element must not be put into operation until assembly is complete. During initial commissioning, until the operating temperature is reached, the secure fit of the heating element must be checked at regular intervals. If necessary, the clamping screws must be retightened to 3 to 3.5 Nm.
Storage
The heating element must be stored in a dry and dust-free environment. If stored in too humid conditions, the insulation material used may absorb moisture, posing a risk of short-circuiting.
