Determination of the permissible watt density
Depending on the intended purpose it is necessary to determine an adequate surface load or watt density of the tube material. This is essential for a for long life cycle and a good and stable operation performance of the heating elements.
The following table gives you a rough idea about the max. surface load of the electric heaters and the ideal sheath material for the specific scope of application. Keep in mind that these are only guidance values and may differ from actual values. Our technical department is available to assist you in finding the most efficient heating solution:
