Features PTC ceramic heating parts and aluminum tube have low thermal resistance, high heat transfer efficiency, surface insulation and high safety. The heater is resistant to moisture and temperature, heating at constant temperature, durable and widely used. High temperature resistant insulation support (temperature resistance 230℃), cable (temperature resistance 200℃) and sheath (temperature resistance 300℃). Using constant temperature ceramic heating technology, continuous output heat, automatic working at constant temperature. Generate heat quickly in 10 seconds, convert electrical energy into heat in 0.1 seconds after ignition and lead to the surface of the aluminum housing in 10 seconds. Feature: 1. The heater has a long service life, can operate 7 hours a day, 24 days a week uninterruptedly and continuously provides a heat source, with a service life of more than 20,000 hours. 2. No open flames, no toxic or harmful gases, some products contain overheating protection and general electrical insulation.
