PTC Insulative heater (PTC Air heater insulator, PTC Heater for warm air-conditioner) is a type of high-power, non-surface-electrified PTC heater with forced air cooling. PTC elements are securely mounted inside an aluminum tube and remain electrically insulated from the tube. Use: This PTC component is designed for heating air or solid materials. The PTC material features a self-regulating characteristic that maintains a constant surface temperature. Advantage: Safe operation, rapid heating, long service life, automatic temperature control, and low noise. Application: Suitable for use in equipment, electric heaters, appliances, and machinery.
