Innovations in detail can make a big difference in everyday use. This is especially true if this innovation leads directly to a tangible improvement in the interface between the product and the user. Such an innovative step is very well proven with the Cool+ handle technology, which is used in WMF cookware series. This is about keeping the handle temperature as low as possible in all practically possible cooking situations, i.e. not to just meet the relevant standards and requirements, but to exceed them greatly.
Many consumers appreciate the superior durability and the outstanding cooking qualities of stainless steel pots. In order to keep the handle temperature as low as possible for stainless steel cookware, it is about preventing the transfer of heat as effectively as possible. At the same time, there is the requirement for a permanently resistant force-fit connection of the handles as well as their feel and the aesthetically successful design. Conventional handle technologies usually compromise here and mostly meet the relevant requirements under the DIN standard as well as the design quality, but could still be greatly improved. This can be seen by using a thermal imaging camera. In the image to the right, you can see the blue handles with Cool+ Technology.
The WMF concept in developing the innovative Cool+ handle technology consists of an extensive reduction in contact surfaces between the pot body and the pot handle. This prevention of heat transfer is made possible by the combined use of high-strength and tensile-stressed stainless steel connection elements with an extremely reduced cross-section. The handles attached to these tension rods are in turn force-fit and permanently supported with insulating "silicon dots" on the opposite side of the pot body. This results in a high strength and insulting handle connection. In order to make this technical feature clearly visible, these "dots“ are made in a contrasting red colour.
During use, both for quick intense heating as well as for long-lasting cooking, the temperatures of the pots equipped with the WMF Cool+ handle technology always remain below the level of comparable products and are always comfortable to touch.
In use, this results in a clear plus for user friendliness through the consistent implementation of a sensible detail innovation, which is used exclusively for WMF cookware and was applied worldwide for a patent.
