Welcome to our store! 1. PTC HEATING PLATE: Upon electrification, the PTC rapidly converts electrical energy into heat energy, which is conducted to the aluminum shell surface within 10 seconds and can be used for extended periods. 2. NO OPEN FLAME: Surface temperature is 200℃, and cable length is 15cm. No open flame, no redness, no toxic or harmful gases, suitable for use in humid environments. 3. CERAMIC THERMOSTAT: The PTC heating element uses ceramic constant-temperature heating technology to continuously output heat and automatically operate at a constant temperature. 4. INSULATION HEAT RESISTANCE: The PTC thermostat heating plate uses polyimide film to wrap the chip inside, which has insulation, temperature resistance, and long-term stable heating performance. 5. LONG SERVICE LIFE: The ceramic thermostat plate can work continuously for 7x24 hours and continuously provide a heat source for more than 20,000 hours, meeting your needs.
