PTC Insulative corrugated heater(PTC Air heater insulator) is a kind of large power Non-Surface-Electrified PTC heater with wind blowing.PTC element is fixed in aluminium tube and keep insulated with the aluminium tube. Insulated air heater with wave frame are dynamic heating elements designed to heat up moving air. The large surface area of the aluminum fins ensures a homogeneous heat transfer adjusting the air volume flow. This system allows an automatic regulations of the heating power within certain ranges. Due to the features, there are many applicaton possibilities. In addition to the standard types, special versions for specific applications are available. It has a lot of advantage as follow: 1. it is safety and reliability. 2. the power is stable. 3. the sound is small. 4. the life is longer. 5. give out the heating continuous. 6. used for wide voltage, from 12V to 240V. 7. dimension is nimble various Applications: PTC Insulative corrugated heater is mainly used in large-power house heater such as cold/warm air-conditioner, eater, disinfecting cabinet, dryer and so on.Product Model BZ/1500 B /300*45*32 A BZ Abbreviation of BiZhuo 1500 means the power of Heating element B indicates a heating element whose surface is not electrified. 300 express the length of product 45 represents width of product 32 means thickness of product A represents the voltage is 220V or above It can be customized orders as per clients specifications. The length , the width, the thickness, how much watt all could customized as per your request.
