This is a 150W PTC (Positive Temperature Coefficient) air heater designed to operate on a 220V AC power supply. Specifically engineered for compact appliance integration, this heating element provides a controlled and efficient source of hot air for robot vacuum cleaners and similar automated cleaning devices.

The 220V 900W & 1000W Drying Corrugated PTC Heater is a specialized, high-performance heating module engineered for modern clothes dryers. Featuring a unique corrugated fin design, it maximizes heat exchange efficiency to deliver rapid, uniform hot air flow—significantly reducing drying time while enhancing energy efficiency. As a self-regulating PTC (Positive Temperature Coefficient) heater operating at 220V, it ensures reliable and safe operation in both commercial and heavy-duty residential drying applications.

PTC (Positive Temperature Coefficient) air heaters are advanced electric heating devices built around PTC thermistor technology. Unlike traditional resistive heaters, their resistance increases exponentially with temperature, enabling self-regulating heat output that eliminates overheating risks.
