Technical Information, Documentation, Case Studies and Tools


Infra red for industrial processes and Spooling/Rewinding are not black arts. There are technical reasons why the correct infra red wavelength and the optimum winding characteristics required for the particular materials should be used. To this end, Double R Controls Ltd have provided technical documents associated with Infra Red, Spooling and Winding.

These documents are available to be viewed online and are continually being updated. Therefore, we recommend that you visit our web site on a regular basis to view the latest version available. Alternatively, if you register your email address to the left, we will inform you when additional technical information is available for you to view online.

The philosophy of Double R Controls is that 'without measurement we know nothing' and therefore, an understanding of your process is of paramount importance. You can, of course, always contact the author of the documents who will be only too willing to provide you with any additional information that you may require.
