PTC Insulated Ripple heating are dynamic heating elements designed to heat up moving air. This system allows an automatic regulation of the heating power within certain ranges. The large area of the aluminum fins ensures a homogeneous heat transfer adjusting the air volume . PTC Insulative corrugated heater(PTC Air heater insulator,PTC Heater for warm air-conditioner) is a kind of large power Non--Electrified PTC heater with wind blowing.PTC is fixed in aluminium tube and keep insulated with the aluminium tube. Due to the features, there are many application possibilities. In addition to the standard types, special versions for specific applications are available., Manufacturer: Ounfhtrttk
