Profins can offer rapid
deliveries of integral low fin tube for use in situations
where extended surface is required, but lack of space
or heat exchanger type dictates otherwise. Material
selection can be carbon steel, stainless steel or copper
based alloys. Profins low fin tubes can be ordered bent
into U-tubes if required. With tube diameters from 5/8"
through to 1" O/D,(15.88mm to 25.4mm) and fin density
ranging from 16 to 36 fins per inch (632 to 1417 fins
per metre) we can accommodate almost any enquiry.
Integral Low Fin Tube has the advantage
that it can improve the thermal performance
of a Heat Exchanger without the necessity
for changing shell size, flow arrangement or the repositioning
of piping.
The external surface of the tube is increased by the
formation of “low fins” by direct extrusion
from the material of the base tube.
