1. The thermal inertia of the electric heating tube is small, the temperature is easier to control accurately, and the use is safe.
2. Improve the thermal efficiency of the electric heating tube while reducing the surface heat load.
3, and not easy to damage, easy to use for a long time.
4, while the metal tube heating heat inertia is large, and it is not easy to control, easy to be dangerous, and is not conducive to long-term stable use of customers.
