Umzimba wokumelana wenziwe nge-stable resistance alloy.I-elementi yeribhoni ilinyazwe onqenqemeni ngendlela ye-helix, bese iphothwa kubakaki be-ceramic.Izinga lokushisa eliqhubekayo langaphezulu aweqi ku-375ºC.Uchungechunge lwe-REWR-G lusetshenziswa kakhulu ekubhulekini kwe-VFD, ukulawulwa kwezimoto, amabhange okulayisha kanye nokusekela okungathathi hlangothi nokunye. Usayizi womkhiqizo kanye nenani kungaklanywa ngokuya ngezidingo zekhasimende, noma kuhlanganiswe kube izingxenye.
