First, the advantages:
1. Rapid heating, aluminum sheet is more compact and has higher thermal efficiency.
2. Healthy, environmentally friendly, glue-free bonding is healthier.
3. Ultra-long, durable, oxidation-free, service life up to 6000 hours.
4. The thermal efficiency of PTC heating element is as high as 99%.
Second, the disadvantages:
1. Not energy saving.
2. Metal electric heating materials, high temperature easy oxidation, power attenuation, short service life. Due to its faceted metal shape, the area in contact with air is larger and the life is shorter than that of wire.
