I want to cool oil for bupes to use as lubricant. I'm assuming I need to cool it down (or do I?)
I have a handy dandy AT/steam turbine box cooling my metal refinement and a cooling loop of PW for the base. THere's room in there for another AT. I was thinking to put a small loop to cool oil a few times through the AT and then have it shunted off the line when its 30C or whatever.
Whats the best way to do this?

I was thinking a temp sensor attached to a NOT gate and then a liquid shutoff that bridges the loop. Anyone have a guide link or advice for this sort of thing?

thanks
