Intended use

Self-recuperative burner ECOMAX

®

 for gas with inte-

grated recuperator for the direct and indirect heating 
of furnace systems in intermittent mode.

Direct heating

Flue gases are returned using an eductor.

Indirect heating

Combustion flue gases are separated from the prod-
uct using metallic or ceramic radiant tubes and ce-
ramic segmented flame tubes,

This function is only guaranteed when used within the 

specified limits – see page 15 (Technical data). Any 
other use is considered as non-compliant.
