What is a radiant tube and what is it used for?
Radiant tubes are fundamental elements in industrial furnaces, designed to transfer heat by radiation without direct contact with the charge. This avoids contamination of the treated material and improves thermal homogeneity inside the furnace.
Main advantages of radiant tubes
- Improved thermal efficiency: uniform heat distribution in industrial furnaces.
- Higher resistance to high temperatures: manufactured with special alloys.
- Reduced maintenance and longer service life: optimized design to reduce failures and wear.
- Energy optimization: reduction of fuel consumption and emissions.
