Zozungulirazinthu zamagetsi zamagetsiimakhala ndi ma cylindrical spirals opangidwa ndi waya umodzi kapena ziwiri zopinga za aloyi yoyenera kutengera ntchito.
Mbali zake zazikulu zikuphatikiza kuphatikiza kwa nickel-chrome alloy wire heat element ndi kupsinjika kwanthawi zonse kwa -230 V.
Zomwe zimagwiritsidwa ntchito nthawi zonse ndi: zowumitsira mafakitale, zotenthetsera mpweya, masitovu, etc.
Komanso, malinga ndi aloyi waya iwo ali, tikhoza kusiyanitsa mitundu itatu ya zitsanzo:

• M zitsanzo, zokhala ndi 20-5 komanso makamaka zopangira masitovu.
• Mitundu ya MS, yokhala ndi mtundu wa 80-20 komanso yothandiza pamapulogalamu onse.
• Mitundu ya MC, yokhala ndi mtundu wa 20-5 ndipo imagwiritsidwa ntchito mu machubu a quartz ndi infrared.
• Mafotokozedwe Akatundu
