Ma coil otsegula ndiye njira yabwino kwambiri yotenthetsera magetsi komanso yotsika mtengo kwambiri pazotenthetsera zambiri.Amagwiritsidwa ntchito kwambiri pamakampani otenthetsera ma duct, zinthu zotseguka za coil zimakhala ndi mabwalo otseguka omwe amatenthetsa mpweya mwachindunji kuchokera pamakoyilo oyimitsidwa.Zinthu zotenthetsera zamafakitalezi zimakhala ndi nthawi yotenthetsera mwachangu zomwe zimapangitsa kuti zitheke bwino ndipo zidapangidwira kuti zisamalidwe bwino komanso zosavuta, zolowa m'malo zotsika mtengo.

Zinthu zoyatsa zotseguka za coil nthawi zambiri zimapangidwira kutenthetsera ma duct process, mpweya wokakamizidwa & ma uvuni komanso zopangira zotenthetsera mapaipi.Ma heaters otsegula amagwiritsidwa ntchito mu tank ndi kutenthetsa mapaipi ndi/kapena machubu achitsulo.Chilolezo chochepa cha 1/8 '' chimafunika pakati pa ceramic ndi khoma lamkati la chubu.Kuyika chinthu chotseguka cha koyilo kumapereka kugawa kwabwino komanso kofananako kutentha pamtunda waukulu.

Zinthu zoyatsira koyilo yotseguka ndi njira yotenthetsera yamafakitale yosalunjika kuti muchepetse kuchuluka kwa watt kapena kutentha kwapaipi yolumikizidwa ndi gawo lotenthetsera ndikuletsa zinthu zomwe zimakhudzidwa ndi kutentha kuti zisaphike kapena kuwonongeka.
