Silicon Nitride Ceramic Air Heating Element Si3N4 Liquid Heating Element

Si3N4 Ceramic Air Heating Element uses high-performance silicon nitride ceramic (Si3N4) as the substrate, has excellent properties such as: high mechanical strength at high temperatures, high thermal shock resistance, acid corrosion resistance, high electric insulation and thermal conductivity. Due to its special formula and the hot pressing manufacturing technology, this product has the following

Features in applications:

High electric insulation strength: No breakdown for 1 minute, at 2500V, 50Hz, and room temperature
High application temperature: maximum 1200 0C in air
High power at unit surface, up to 25 W/cm2
Small thermal inertia and fast heating
Acid and alkali corrosion resistance
Small size
Long life

Typical applications include:

Die heater
Packaging machinery heater
Tobacco equipment heater
Industrial heating equipment
Hot and cold drink machine heater
Burner appliance ignition system
Welding furnace heating
Petrochemical industry heater
High temperature ignition

Caution during application:

Sudden cold and sudden heat are strictly prohibited in working environment
At high temperature, the hot surface of element should avoid from splashing water or other liquids
