In addition to the support given by its technical personnel, Suntec provides to its customers an on-line tool for the calculation of heating elements, that can be activated by a dedicated code. The functioning is very simple: the user has to choose the type of heating element (mat, strip, snake, one-line) and then he has to enter the desired dimensions. The system automatically calculates the actual dimensions and voltage according to constructive tables. There is also the possibility to download a Pdf file and/or to print the obtained result.
