The highest quality for finned tubes THE PERFORMANCE DEGRADATION OF A HEAT EXCHANGER IS ESSENTIALLY DUE TO TWO PHENOMENA WHICH OCCUR OVER TIME: • Fouling resistance due to impurity accumulation contained in both fluids • Increased thermal resistance at the tube-to-fin bond due to thermal cycling dilatation of the materials and to corrosion at the fin base or root. These factors creates a loss of contact or bond pressure in between the fins and the tube. Extruded finned tubes HOW TO PREVENT LOSS OF PERFORMANCE ? • Fouling impact on heat exchanger performance can be reduced by an internal and external cleaning on a regular basis. • There is No remedial solution (except tube replacement) for correcting performance degradation due to increased tube-to-fin resistance but this can be prevented by using aluminum extruded finned tubes. WHY POWERFIN ALUMINUM EXTRUDED FINNED TUBES PREVENT LOSS OF PERFORMANCE DUE TO TUBE-TO-FIN BOND RESISTANCE ? • The aluminum completely encloses the tube material, No gap between fins No possibility of contaminant accumulation underneath the fins No possibility of corrosion in between fins and tubes. Aluminum which completely covers the tub

Extruded aluminum fin attachment* • More than 1200 psi (>85 bars) applied on aluminum when forming the fins on tubes Excellent mechanical bond No risk of fin detachment over the years due to thermal dilatations or vibrations. OTHER IMPORTANT BENEFIT OF POWERFIN ALUMINUM EXTRUDED FIN TUBES : • Cold forming finning process Much more rigid fin than aluminum ribbon of same thickness Easy maintenance (severe coil cleaning without fin damage) Did you know ? EXTRUDED ALUMINUM FINNED TUBES ARE ALSO CALLED : • Integral aluminum finned tubes due to the fact this is the only fin technology where...
