Izinto zekhoyili ezivulekileyo lolona hlobo lusebenzayo lwento yokufudumeza yombane ngelixa ikwayeyona inokwenzeka ngokwezoqoqosho kuninzi lwezicelo zokufudumeza.Isetyenziswa kakhulu kwishishini lokufudumeza umbhobho, izinto zekhoyili ezivulekileyo zinezijikelezo ezivulekileyo ezifudumeza umoya ngokuthe ngqo kwiikhoyili ezixhonyiweyo.Ezi zinto zokufudumeza kwimizi-mveliso zinamaxesha obushushu okukhawulezayo aphucula ukusebenza kakuhle kwaye zenzelwe ukugcinwa okuphantsi kunye nokulula, iindawo zokutshintsha ezingabizi kakhulu.

Izinto zokufudumeza iikhoyili ezivuliweyo ziqhele ukwenzelwa ukufudumeza inkqubo yombhobho, umoya ngenkani kunye nee-oveni kunye nokufakwa kokufudumeza kwemibhobho.Izifudumezi zekhoyili ezivuliweyo zisetyenziswa kwitanki nakwimibhobho yokufudumeza kunye/okanye kwityhubhu yesinyithi.Ubuncinci bemvume ye-1/8 '' iyafuneka phakathi kwe-ceramic kunye nodonga lwangaphakathi lombhobho.Ukufakela i-coil element evulekileyo iya kubonelela ngokugqwesileyo kunye nokusabalalisa ukushisa okufanayo kwindawo enkulu.

Izinto ezivulekileyo zesifudumezi sekhoyili sisisombululo esingathanga ngqo sokufudumeza kwimizi-mveliso sokunciphisa iimfuno zoxinaniso lwe-watt okanye ubushushu bobushushu bommandla womphezulu wombhobho oqhagamshelwe kwicandelo elifudumalayo kunye nokuthintela izinto ezibuthathaka zobushushu ekuphekeni okanye ekuqhekekeni.
