LOW-FIN TUBE EVER FIN L


Outline
Ever Fin L is a heat transfer tube formed integrally with low fins on its outside. The tube's outside surface area is remarkably expanded due to the tube's outside fins and the heat transmitting ability is greatly improved. Ever Fin L has been widely used in freezing, air conditioning, and petroleum plants and others because it can reduce the size of heat exchangers and help reduce expenses shapely.;

Features
  • High heat transfer performance
    Integrated with low fins on its outside, the tube has excellent heat transfer performance as well as durability.
  • Wide range of materials
    The tube can be manufactured using a variety of materials including copper, copper alloys, low carbon steel, stainless steel, aluminum alloys and titanium.
  • Making heat exchangers compact and lightweight
    Because of its superior heat transfer performance compared to smooth tubes, EVER FIN L can reduce the number of tubes, thus making heat exchangers compact and lightweight.
  • Wide variety of fin configuration
    Tubes with various fin pitches are available. Furthermore, both tube ends and the land portion on its middle may optionally be left un-finned, which makes it possible to fix the tube onto tube plates in the same way as for smooth tubes.


Use
Heat exchangers for turbo refrigerator, absorption type refrigerator and screws; general refrigerators, petrochemical plant equipment, boilers and solar energy equipment.
