220V 100W PTC Ceramic Heating Element for Fast and Safe Incubator Use

PTC Air Heater 220V 100W - Insulated PTC Thermistor Element. Key benefits and why you need this product: - Self-regulating PTC technology provides automatic temperature control without external thermostats, which reduces installation complexity and improves reliability. - Fast warm-up and consistent heat output deliver effective air heating for small systems and appliances. - Surface insulation and high-temperature silicone wiring improve safety and electrical isolation during operation. - Low operational noise and long service life make it suitable for continuous or intermittent use in appliances and equipment. Main specifications: - Nominal power is 100 W. - Nominal voltage is 220 V AC/DC, and the power leads are not polarized so they can be connected without regard to positive or negative. - Overall dimensions are 113 x 35 x 26 mm. - Mounting hole spacing is 103 x 22 mm. - Mounting hole size is 8 x 4 mm. - Heating element material is a PTC thermistor. - Heating method is heat radiation assisted by an airflow. - Connection cable is high-temperature silicone with a total length of 200 mm and 10 mm of stripped conductor. Construction and performance details: - The PTC element is fixed inside an insulated aluminum tube and fitted with aluminum fins to provide a large surface area for uniform heat transfer. - The design is optimized to adapt heating output to airflow, enabling stable operation across a range of air volumes. - The insulated finned construction isolates the heating element electrically while maximizing thermal transfer to the passing air. - The heater operates with low audible noise and is engineered for long service life under normal operating conditions. Compatibility and common applications: - Compatible with 220 V systems used in air conditioners and electric heaters. - Suitable for integration in automotive heating systems and vehicle auxiliary heaters. - Ideal for use in air curtain machines, humidifiers, incubators, and general household and commercial appliances that require directed warm air. - Custom versions for other power ratings, sizes, and voltages are available from the manufacturer for specific application needs. Practical use scenarios: - In a small ducted air conditioner, the PTC air heater provides rapid supplemental heating while maintaining stable temperature without additional control electronics. - In an automotive cabin heater, the unit supplies quiet, self-regulated warm air to improve comfort during cold starts. - In a humidifier or air curtain machine, the insulated fin design delivers uniform heat to the airflow while maintaining electrical isolation from the air path. Packaging and lead time: - Standard packaging is 50 pieces per carton. - Typical delivery lead time is 1 to 3 days for stocked items. Ordering and customization: - Custom sizes, power levels, and voltages are available to match specific equipment requirements.
