Finned radiant tubes
Open tube systems have been used for many decades, primarily for tempering furnaces. The recuperative burner systems, however, are relatively new.
AVION finned radiant tubes offer a larger surface area considerably improving their heat efficiency and distribution.
Because the fins are thread-shaped, an optimum flame distribution from the burner tip to the tube exit is achieved.
Further advantages of Si / SiC radiant tubes are:
- durability and reliability at temperatures up to 2450°F / 1350°C
- outstanding resistance against: thermal shock, overheating, oxidization, carburizing, creep elongation, corrosive atmospheres, vibration, magnetizing, residues of detergents
heat flow: 125 BTU/in² / 7800 kWh/cm²
