Isifudumezi sokuntywila seflange sithatha idyasi yetyhubhu yensimbi engenasici, i-magnesium oxide powder eguqulweyo, i-high-performance nickel-chromium electrothermal alloy wire kunye nezinye izinto. Olu chungechunge lwe-heater yamanzi e-tubular lunokusetyenziswa ngokubanzi ukufudumeza amanzi, i-oyile, umoya, isisombululo se-nitrate, isisombululo se-asidi, isisombululo sealkali kunye nentsimbi ephantsi yokunyibilika (i-aluminiyam, i-zinc, i-tin, i-alloy ye-Babbitt). Inokusebenza kakuhle kokufudumeza, ubushushu obufanayo, ukuxhathisa ubushushu obuphezulu, ukumelana nokugqwala kunye nokusebenza kakuhle kokhuseleko.
