<div dir="ltr">Hi Darrell,<div><br></div><div>IMHO, I would recommend against your planned course of action. </div><div><ol><li>All coolers on air compressors are placed between the pump and the tank where the air is the hottest and the heat transfer will be the greatest.. In your design, most of the heat will be absorbed by the tank before it gets to the radiator. It will not be an efficient heat transfer located after the tank.</li><li>I also believe that putting it on the tank outlet will restrict your flow as that is where you need the maximum flow. You can take advantage of the "surge capacity" of the tank which is only limited by the size of the piping from the outlet of the tank to the air device you are using. Placing a cooler between the tank and the air device could limit the flow of the tank to the device.</li><li>If you put it between the pump and the tank, the cooler only needs to flow at the capacity of the pump (e.g., 10CFM). You potentially could get 100X that flow out of the stored capacity of the tank if the piping is large enough. You do not want any restriction between the tank and your air devices</li><li>Whatever you choose to do for a heat exchanger, I sincerely believe that it will not be effective, and it probably will diminish the overall performance of your system, if you do not put it between the pump and the tank.</li></ol><div>IMHO</div></div><div><br></div><div>doug</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Aug 12, 2020 at 8:53 AM Darrell Walker <<a href="mailto:darrellw360@mac.com">darrellw360@mac.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div style="overflow-wrap: break-word;"><div><br></div>The transmission cooler I’m looking to use is a "stacked plate” design, and has a pressure rating of 200 PSI.

<div> <font size="3">That's a clever idea. It is an excellent heat exchanger and is good for the pressure. But it could restrict air flow. Most are just a long, serpentine tube with fins. It all depends on what air tools you are using. It is possible that you couldn't run a sand blast cabinet through it. But you could hook up the high volume users to bypass the cooler and save the dry air for the tools that need it.</font><br>

I’d be concerned with using a transmission cooler for an aIr cooler because they are not designed for pressure use. I wouldn’t think a trans cooler would need to be rated at more than 10psi. </blockquote></div>

<div>An air conditioner condenser would probably be better. It even has "condenser" in the name.... </div>
