Bimetalic tubes
Aluminnium fins are rolled onto the base tube of optional material .
Parameters:
- enternal diameter of base tube Dz = 12 - 38 mm
- diameter around fin D = 15 -70 mm
- max. height of fin h = 16 m
- lead of fin s = 1,5 - 4,5 mm
- max. lenght of finned tube L = 12 m
Heatransfer coeficient between enternal tube and fins is 0,0002 m2 K/W.
