(1) There must be a temperature control system (electric control cabinet) in the oven, which ensures the life of the oven electric heating tube of the oven and safety.
(2) When installing the electric heating tube into the dryer machine, please pay attention to the followings:
In the circulating air duct, the dryer machine electric heating tube has heat exchange by convection, also has radiative heat exchange, and it is related to the installation position. The electric heating tube is installed in the middle position, which has high temperature on the surface of the tube, but low temperature if is installed on the side position. So in order to increase the surface load of dryer machine electric heating tube, the number of horizontally arranged electric heating tubes should not be too much.
