Ma coil okhazikika a nthunzi, makamaka a Model S, amapangidwa ndi maulumikizidwe mbali zina za coil. Mtundu uwu wa coil umalola nthunzi kulowa mu supply header ndikugunda mbale kuti igawire nthunzi ku machubu onse. Kenako nthunzi imaundana motsatira kutalika kwa chubu ndikutulutsa mutu wobwerera.

Advanced Coil imalimbikitsa kuti kutentha kwa mpweya kupitirire 40°F. Timapanga chitsanzo ichi ndi maulumikizidwe mbali zosiyana za coil. Ma coil okhazikika a nthunzi amagwiritsidwa ntchito m'mafakitale osiyanasiyana opumira mpweya komanso ntchito zowumitsa m'mafakitale osiyanasiyana. Kawirikawiri, ma coil mu mndandanda uwu amasankhidwa pamene kutentha kwa mpweya komwe kukubwera kuli pamwamba pa kuzizira ndipo mphamvu ya nthunzi imasungidwa pa kupanikizika kosalekeza.

Ma coil a Type S amapezeka ngati ma coil ozama a mzere umodzi ndi mizere iwiri okhala ndi kulumikizana kwa nthunzi kumapeto amodzi ndi kulumikizana kobwerera kwa condensate kumapeto ena. Timaonetsetsanso kuti chitsanzochi chili ndi chubu cholumikizidwa ndi TIG panthawi yomanga, ndipo timatha kupereka sitampu ya ASME 'U' kapena kapangidwe ka CRN.
