Pressurized dyno cooling system

[R.Brown]

I have been running a pressurized cooling system, by modifying the cooling tower to withstand the higher pressures and using a pop-off type valve with a spring set to whatever pressure we want.

It has worked alright, but the spring needs to be replaced often, and I always am nervous when we try the higher pressures like what we run on the racetrack.

So.... After some discussion with Depac Dave it was suggested I try a water bath type system, where we use a standard radiator submerged in water, and control the "bath" temperature with cool water.

I already do something like this with a submerged oil cooler to keep oil temps consistent, so I think it should work, and be pretty painless to build.

Anyone else out there doing something similar?

I've done this with both water & oil just like you mentioned, no real problems other then space and thats not a big deal as you can put it across the room if you want to. Tempcontrol takes some work but agian not to hard.

Another way might be to use a marine type heat exchanger.

Go to these guys & get a spring made of the right material to withstand the temps..http://www.centuryspring.com/ or http://www.americanprecspring.com/ or http://www.generalwirespring.com/index.html or http://www.springsfast.com/index.html

I agree with Adger. We've done it both ways & while the radiator set-up works fine - there is a bit more service & maintenance involved.
