Alkaline Immersion Heater is made out of S.S316L; it is used for Heating alkaline solutions, wax, paraffin, Solvent vapor cleaning, salt baths and soft metal melting. Most Alkaline cleaning solutions, detergents and Chemicals are normally corrosive to mild steel. Thus, for heating water or alkali solutions, wax, paraffin, and fuel Oil pre-heating vegetable or mineral Oils, picking, quenching and rinsing solution soft metal melting, solvent Vapors cleaning, electroplating solution, chromic phosphoric, our alkaline heaters are used.
