Dairy Plate Chiller

[a-slayer]

These plate chillers are not used for cooling milk from body temperature. They are used, you have two of them in a dairy, for rapid heating up to 75c, for pasteurisation then rapid cooling down to about 3c.
I don't think it will have any problem with cooling your wort.

I have a dairy and I use a plate cooler to pre-cool milk from cows body temperature before going into the bulk tank to finish the cooling, it is doing the job it was designed for and that is nothing to do with pasteurization.

Interesting, they are also used for pasteurisation though, well that's how we used to do it, it's been a few years though since my Dad had a dairy.
