Si/SiC radiant tubes are offering unsurpassable physical properties, faster heat-up times, longer life, and higher efficiency at competitive prices.

An innovation in the radiant tube technology without changing your burners.
Si/SiC radiant tubes are made of natural raw materials according to a particular process. Their advantages in comparison to conventional tubes made of heat-resistant high-quality steel or monolithic ceramics include:

• durability and reliability at temperatures up to 2450 °F

• outstanding resistance against:

• thermal shock
• overheating
• oxidation
• carburization
• creep elongation
• corrosive atmospheres
• vibration
• magnetization
• residues of detergents

heat flow: 110 BTU/in²

Si/SiC radiant tubes can be used in all heat treatment processes in gas or electrically heated hardening or tempering furnaces and adapt to your existing burners.
The tubes can be supplied with open ends, closed ends (recuperative system) and with corresponding flanges.
Exchange systems ready for installation with radiant and flame tubes up to
6” diameter made of Si / SiC composite material for recuperative burner equipments are available immediately.

Si/SiC recuperative radiant tubes are absolutely maintenance-free.
