Features

Self-Regulating & Safe: The PTC characteristic means the power output automatically adjusts based on ambient temperature. As the temperature increases, resistance rises, reducing power consumption. This prevents overheating and eliminates the need for external thermal fuses or thermostats in most applications.

High Thermal Efficiency: The corrugated or comb-type aluminum fins significantly increase the surface area for heat dissipation. This structure maximizes heat exchange with the surrounding air, ensuring rapid warm-up and uniform temperature distribution.

Durable Construction: The aluminum fins and tube construction are resistant to oxidation and corrosion. The all-metal design is robust, vibration-resistant, and suitable for demanding environments.

Wide Voltage Compatibility: These heaters can operate effectively across a wide voltage range without significant changes in surface temperature, making them ideal for unstable power grids or applications with fluctuating voltages.

Customizable Design: Available in various shapes (flat, circular), sizes, voltage ratings (110V-400V), and power outputs to meet specific customer requirements.

Application

Due to their superior safety features and efficient heat transfer, comb-type finned PTC heaters are widely utilized in:

•HVAC Systems: As auxiliary or primary heating elements in air handling units, fan coil units, and duct heaters.

•Automotive Industry: For cabin heating in electric vehicles (EVs), defrosting systems, and battery pack thermal management.

•Household Appliances: In dehumidifiers, hand dryers, hair stylers, and food warming cabinets.

•Industrial Equipment: For anti-condensation heating in switchgear cabinets, control panels, and communication base stations.

•Medical Devices: Providing controlled and reliable heat in incubators and diagnostic equipment.
