Arinox

“Heat exchange” is a process or a fundamental step for very widely differing applications: From the production and the distribution of heat for domestic and industrial uses, to refrigeration in the widest sense (eva- porators and condensers), from the cooling of fluids used in manufacturing processes to heating for domestic uses. Arinox produce a wide range of stainless steel strip, which is particularly suitable for the production of: Plate heat exchangers consisting of corrugated stain- less steel plates coupled using braze welding, or with gaskets (in this case the pack of plates is mounted on a frame and assembled with tie rods). Heat exchangers with finned pipes. In this case the stain- less steel fins are pressed with a particular undulation for the purpose of increasing the heat exchange and then wrapped in a spiral along the tube to permit the load drop to be contained. Heat exchange batteries for air conditioning and heating. In this case the stainless steel plates that make up the finned pack are pressed and holed for later welding to the pipes.

During the later pressing stage, these often interfere with the smooth flowing of the material (in the press) and can therefore reduce the efficiency of the tools used for working the strip, over time. Arinox have overcome these matters once and for all with the exclusive process: SUT ® (Surface Ultra-cleaning Treatment). Through an electrochemical treatment, this process makes it possible to remove the initial surface layers of the material and therefore enables a totally clean and impurity-free surface to be obtained. SUT ® technology is particularly indicated for applications with deep drawing and anyway in all those cases where a lower tool wear is required such as for components in the electronics and precision engineering industries.
