Kwiimoto zombane ezicocekileyo, ibhetri ebhodini ibhetri ephezulu, kwaye i-heater yombane iya kukhetha ngokubanzi i-voltage ephezulu, kuba i-voltage iphezulu kwaye amandla ombane afanayo anokuguqulwa abe ngamandla obushushu ngakumbi.
Ngokwendlela isifudumezi sombane se-PTC esisebenza ngayo sinokwahlulwa ngokufudumeza ngqo komoya kunye nokufudumeza komoya ngokungangqalanga ngokufudumeza amanzi.Umgaqo wokufudumeza ngokuthe ngqo komoya kunye nesomisi seenwele zombane, ngelixa uhlobo lokufudumeza kwamanzi lusondele kwindlela yokufudumala.
Imveliso eyaziswa ngeli xesha yi-PTC air heater.
