Temperature range:
Low temperature: less than 160 degree Celsius (insulators thickness: 80mm)
Middle temperature : from 160 degree Celsius to 200 degree Celsius (insulators thickness:100mm to 150mm)
High temperature: from 200 degree Celsius to 650 degree Celsius (insulators thickness: 300mm)
Advantage:
1. During heating, air max temperature can reach 650 degree Celsius, but the surface temperature of the shelth is just around 50 degree Celsius
2. Heat efficient is more than 95%
3. Temperature raise rate : 10 degree Celsius per second during working
4. The heating elements is made of high temperature alloy with good mechanical character
5. Usage time:standard more than 10 years
6. Clean air, small volume
7. Made as client design
8. After reached the max temperate, the working wattage can reduce to half
Shortage:
1. Surface pressure : less than 0.3kg/cm2
2. Just can be used to heat air
