INNOVACERA’s silicon nitride heating elements are normally rectangular in shape. These heaters have a lot of operation zone up to 1000 degree C and a cold zone in the contact area. The encapsulated terminal can prevent short circuit caused by conductive contamination. They can be operated with or without a controller. Silicon nitride heater has several times the durability that silicon carbide products.
The performances of Si3N4 ceramic heater:
1) Electrical safety. The current leakage after the break is less than 10 mA
2) High-temperature resistance. Dry point up to 1300 ℃
3) High surface load. Heating liquid surface load up to 78w/cm2
4) Small size
5) The thermal inertia is small, faster heating up.
6) Long service life
7) Acid and alkali corrosion resistance
Their have specification as below:
1) Rated Voltage: 230V，220V，110V，120V
2) Hz: 50/60HZ
3) Rate power
500-3500W
4) Max Power: 3500W
5) Service life: 5000 hours
6) Electric insulation strength: 2500V、50HZ (Room temperature)，no breakdown in 1 minute
7) Leakage of current: No more than 0.025 mA under normal working conditions, no more than 10 mA in water after breaking
8) Acid corrosion resistance: Boiling in 5% sulfuric acid solution for 6h, the corrosion rate is less than 10g/m2•h
9) Alkali resistance: Boiling in 30% sodium hydroxide solution for 6h, corrosion resistance less than 0.6g/m2•h
10) Medium: liquid, water
11) Dimension, power and input voltage are customize according to your requirement. Stock dimensions as below:
