Feature: 1. Using PTC ceramic heating parts and aluminum tube, low thermal resistance, high heat transfer efficiency, insulation and high safety. 2. Moisture and temperature resistance, constant temperature heating, durability, safety protection, accuracy design, wide application. 3. Insulation high temperature resistant bracket (temperature resistance 230℃), wire (temperature resistance 200℃) and sheath (temperature resistance 300℃), can run for a long time in an environment with humidity less than 90%. 4. Use ceramic constant temperature heating technology to continuously output heat and automatically work at constant temperature. 5. Quickly generate heat within 10S. After power‑on within 0.1S Neijiang electric energy is converted into heat energy, which is conducted to the surface of the aluminum shell within 10s. 6. Long service life, 7/24 uninterrupted work, continuous supply of heat source, service life over 20,000 hours. 7. No open flame does not turn red, no toxic and harmful gases, some products contain over‑temperature protection, and the overall surface is electrically insulated.
