Production Process

A high temperature resistance wire is placed in the metal tube, and the crystalline magnesium oxide powder with good insulation and thermal conductivity is tightly filled in the gap, and the heat is transferred to the metal tube through the heating function of the heating wire, thereby heating up. The stainless steel cylinder is used, which is small in size, occupies less space, is easy to move, and has strong corrosion resistance. A thickened thermal insulation layer is used between the stainless steel inner tank and the stainless steel outer shell, which minimizes temperature loss, maintains temperature, and saves electricity.
