1. Confirm the working environment and heating medium,these factors are helpful to the design for the surface load.
2.Confirm the volume of the heating target,how many degree from low -high temperature.
3.The target degree of the heating object determine the heating element's material,the surface tube temerature can be 0-900°。
4.The heating element's application,dimensions ,voltage and power.
5.The assemble way is drilling hole or plug-in?Different assemble way determine the shape of the heating element.
