1. Long service life, no maintenance, no maintenance replacement cost; Service life up to 10 years. Don't need maintenance, basic no maintenance costs. 

2. High efficiency and energy saving: hot start very fast and the average preheating shorten by more than 60% time than the circle of resistance heating mode, thermal efficiency is as high as 90% above at the same time, under the same condition, than resistance coil heating power saving 30-70%, greatly improving the production efficiency. 

3. Accurate temperature control, real-time accurate temperature control, improve product quality, high production efficiency. 

4. Good insulation, electromagnetic coil to customize special cable winding resistance to high temperature and high pressure, insulation performance is good. 

5. Improve the working environment: the way of internal heat, heat accumulation in the heat inside the body. Equipment surface temperature can be improved to the human body can touch, greatly improved the production field work environment, strong production workers enthusiasm, reduce the plant ventilation cooling costs in summer
