Optimum temperature for perfect products Heat is a key process application in many industries, especially in cable manufacture, where the German company Kurre Systems is a specialist. In the field of heating and thermal systems, Kurre Systems offers a large portfolio that is constantly being expanded.

“A broad field in which heat is used is the desizing or degreasing of products,” said designer Jakob Luft. “In our tube ovens, for example, cables and wires, but also tapes of all kinds, are effectively solved from unwanted substances – even over long distances. A defined, homogeneous temperature distribution and very good temperature constancy are particularly important to us. We also focus on sustainability by minimising energy losses. We achieve the latter in particular through sophisticated insulation concepts.” Occupational safety is also a priority. For example, the surface temperatures of Kurre’s tube furnaces remain well below the permissible limits, even when temperatures of more than 600°C are reached inside. The design of the tube oven was recently further developed: the centre section now consists of two half shells that form the full shell when closed. This simple idea removes the laborious

inserting of the product to be treated. In the open position, the oven simply moves over the product and locks it in the centre in its final position. In the case of a malfunction, this mechanism allows quicker separation of product and oven without damaging the product or injuring the operator. The modular design allows variation of the effective heating distance. The further development of the design also enables a space-optimised stacking arrangement in the form of a deflection oven. In addition to tube furnaces, Kurre Systems develops other heating concepts, tailor-made to individual customer and product requirements. Recent examples include solutions for treating fluorine or carbon materials in both round and tape-shaped configurations. Kurre Systems frequently designs systems or individual machines for this purpose that carry out cleaning processes or initiate structural changes in the thermoplastic, so that the material can be specifically supplied to the downstream processes with the desired properties.
