A Basco Model 08060 Type 500 shell and tube
heat exchanger with 3/8" copper tubes was used as a lube oil cooler in
a Joy Turbo Compressor. The Joy Compressor has two Inter Coolers (plate fin,
air on shell side, water on the tube side with 5/8" tubes). The lube
oil cooler has oil on the shell side and cooling water on the tube side.
Fouling in these lube oil coolers would cause a drop in performance after
six months and needed replacement within twelve months. At the end of the
twelve month period the tubes would be nearly plugged solid.
