Extruded finned tubes are main devices for air coolers and the common application fields are:

� Heat exchangers for power plants ( electric, nuclear, thermal and geothermal power plants ).
� Steam condensate systems.
� Chemical and petrochemical industry.
� Food processing plants and refrigeration technology.
� Industrial ( steel mills, incinerators, gas compression facilities ).
