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.
The Tubular Air Heater has the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, easy installation, and long service life. It is widely used in aviation, shipping, petroleum, chemical industry, washing, chemical fiber, machinery manufacturing, automobile, motor, radio, instrumentation, plastic, textile, food, printing and packaging, rubber, medicine and health, household appliances and other industrial sectors, and is used in fusible metal melting furnaces, air heating furnaces, drying ovens, hot pressing molds and other equipment.
1. Heating element material:
Shell material: various stainless steels, copper, etc.
Electric heating alloy wire: nickel-chromium, iron-chromium alloy
Filling material: crystallized magnesia sand
2. Heating temperature range:
Tubular Air Heater can reach up to 450℃ at room temperature (depending on the model and design)
3. Power range:
Depending on different models and application requirements, the power can range from tens of watts to hundreds of kilowatts
4. Structural features:
