One big problem I experienced in the outback was a hail storm with hail the size of golf balls. The fins were bent so much that air flow was drammatically reduced. Just another gem in your HAZOPS --- mechengr1977 <mechengr1977@yahoo.com> wrote:

fin fan is actually  trademark by Hudson (now McDermoot) and has now been accpeted as the generic desc for finned air coolers whtether induced or forced. We have use of lot of these fin fan coolers (Hudson and GEA) in our condensing system. Most of the problems that i have been involved with is assoicated with the accumulation of dirt in the tube banks, high vibration of the fan, and corrosion of the finned tubes.  My guess is the buckling of the tube is a low risk failure event due to the inherent operating limits of the cooler itself. We have actually consider such event the first time we have tried using a ferrules supplied by CTI to repair a leaking fin fan tubes.
