Ceramic radiant tube SER-C

  Burner seal

  Flange connection

  Radiant tube (SiSiC)

4

  Mounting gasket

For heat treatment processes in which combustion 
gases must be kept separate from the product. The 
patented flange connection is gas-tight.
Material: SiSiC, max. application temperature: 

1300°C.
The SER-C is not supplied with the ECOMAX

®

 and 

must be ordered separately.

Flue gas guide tube FGT

To guide the flue gases if smaller burners are used 

than those normally intended.
Material: vacuum moulded pulp.

Available on request in different sizes suitable for the 

SER-C radiant tube and ECOMAX

®

 burner sizes.

Segmented flame tube SICAFLEX

®

Segmented ceramic flame tubes to guide hot flue 
gases in radiant tubes.
Material: SiSiC.

The SICAFLEX

®

 is not supplied with the ECOMAX

®

 

and must be ordered separately.

P/P set Eco

Nozzle to limit the volume of purging air in order to 
achieve safe ignition and monitoring of the ECOMAX
