Cool cooling tower

Back in the fifties and early sixties dairy farms had to find a way to cool milk until the truck arrived and picked it up and so they used a system that used a cooling tower to cool water and then in turn that water cooled the milk in an inside out radiator contraption , so when they came up with refrigerated vats cooling tower became obsolete, the farm next to me still had a tower standing and when the fires destroyed the dairy I asked if I could have the tower to put it up on my farm to explain to people that this is how we cooled things in the past.

After several years of sitting in the bottom tank cooling off in the summer it was discovered that the legionella bacteria was present in the water so no more sitting in it.
