EVER FIN delta


Outline
Answering the demand for a heat transfer tube with a heat transfer capability greater than Ever Fin L, Furukawa Electric developed Ever Fin . There are two types of Ever Fin ; for boiling and condensing. In comparison with the former Ever Fin L, a higher coefficient for overall heat transfer has been obtained. This product has been widely used for air conditioning and freezing equipment, binary system, etc.

Features
  • High heat transfer performance
    In comparison with the conventional EVER FIN L with 26 fins for general use, the performance of EVER FIN has drastically improved; 2-10 times in terms of outside heat transfer coefficient and 1.3-3 times in overall heat transfer coefficient.
  • Excellent boiling heat transfer performance
    EVER FIN provides excellent heat transfer performance at small temperature differences, so that it is best suited for energy saving equipment.
  • Making heat exchangers compact and lightweight
    Due to its superior heat transfer performance compared to low-fin tubes, EVER FIN can reduce the heat transfer area needed for heat exchange, thus making heat exchangers compact and lightweight.
  • Wide range of tube geometry
    Tube's both ends and the land portion on its middle may optionally be left un-finned, making it possible to fix the tube onto tube plates in the same way as for smooth tubes.
