Features Using PTC ceramic heating parts and aluminum tube, low thermal resistance, high heat transfer efficiency, insulation and high safety. Moisture and temperature resistance, constant temperature heating, durability, safety protection, precise design, wide application. High temperature resistant insulation backing (temperature resistance 230℃), wire (temperature resistance 200℃) and sheath (temperature resistance 300℃), can work long time in environment with humidity less than 90%. Use constant temperature ceramic heating technology to produce heat continuously and work automatically at constant temperature. Quickly generates heat in 10 seconds. After powering on in 0.1s, Neijiang electric energy is converted into thermal energy, which is conducted to the surface of the aluminum shell in 10s. Features: 1. Long service life, 7/24 continuous work, continuous heat source supply, service life over 20,000 hours. 2. No open flame turns red, no toxic and harmful gases, some products contain overheating protection, and the overall surface is electrically insulated.
