Industrial Furnace Radiant Tubes for Annealing, Quenching & Carburizing | FH®

FH® U-type radiant tubes are high-performance heating elements used in indirect heating furnace systems. They are designed to deliver uniform heat distribution, excellent thermal efficiency, and long service life in high-temperature industrial environments.
Compared with direct-fired heating, U-type radiant tubes provide cleaner, more controlled heating, making them ideal for precision heat treatment processes.
Our radiant tubes are widely used in carburizing, annealing, and continuous furnace systems across global industries.
