• 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

• 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
