Mtundu wa G wophatikizidwa ndi spiral finned chubu umakonzedwa kuchokera m'lifupi mwake mu chitoliro chachitsulo ndi kuzama kwa poyambira, kenako ndikuyika riboni pa chitoliro chachitsulo ndi zida.Mu mapindikidwe ndondomeko, monga chisanadze zomangitsa mphamvu kumlingo winawake kotero Mzere adzakhala mwamphamvu mu ozungulira poyambira, kuonetsetsa pali kukhudzana m'dera pakati zitsulo gulu ndi zitsulo chitoliro.Pofuna kupewa kuti kasupe wa Mzere usagwe pa chubu chounikira, mbali ziwiri za mzere wachitsulo ziyenera kuwotcherera pachitoliro chachitsulo.Kuti mukhazikike mosavuta, payenera kukhala pakati pa lamba wachitsulo ndi groove yozungulira.Ngati chilolezocho chili chaching'ono kwambiri, njira yokhazikitsira idzakhala yovuta kuti ichitike bwino.Kuphatikiza apo, lamba wachitsulo wokhotakhota nthawi zonse pamakhala kuchuluka kwa rebound, zomwe zimapangitsa kuti zisagwirizane bwino pakati pa lamba wachitsulo ndi pansi pa spiral groove.Zipsepse zophatikizika zimatha kuchitidwa pazida wamba, ndipo zimakhala zotsika mtengo.Makampani a Mcelroy ku United States omwe ndidagwiritsa ntchito zida zopangira zida zapamwamba, ukadaulo wolumikizira slotting ndiwotsogola, kuchokera ku khola, lokhazikika, lokhazikika, lotulutsa mphamvu zosachepera 70 n, kutentha kovomerezeka kumatha kufika 400.℃,ali ndi mphamvu yamphamvu yokana kutentha ndi kugwedezeka kwamafuta, amagwiritsidwa ntchito kwambiri mu petrochemical air cooler.
