The Tubular Air Heater is an efficient and reliable electric heating element designed for heating air. It uses a metal tube (such as stainless steel, copper, etc.) as the outer shell, and spiral electric heating alloy wires (such as nickel-chromium, iron-chromium alloy) are evenly arranged along the central axis inside, and the gaps are filled with crystalline magnesium oxide sand with good insulation and thermal conductivity. Silicone seals are used at both ends of the tube to ensure the sealing and safety of the element. The electric heating alloy wire is heated by electric current, and the heat is transferred to the metal tube through magnesium oxide powder, thereby heating the surrounding air.
