Isifudumezi sokucwiliswa kwe-flange sisebenzisa ijazi leshubhu lensimbi engagqwali, impushana ye-magnesium oxide eshintshiwe, intambo esebenza kahle kakhulu ye-nickel-chromium electrothermal alloy wire nezinye izinto. Lolu chungechunge lwe-heater yamanzi e-tubular lungasetshenziswa kabanzi ekushiseni amanzi, uwoyela, umoya, isixazululo se-nitrate, isisombululo se-asidi, isixazululo se-alkali kanye nezinsimbi ezincibilika kancane (i-aluminium, i-zinc, ithini, i-Babbitt alloy). Isebenza kahle ekushiseni, izinga lokushisa elifanayo, ukumelana nokushisa okuphezulu, ukumelana nokugqwala nokusebenza okuhle kokuphepha.
