I put a radiator between the output of my 5hp two stage pump and the tank mounted on the belt guard. The fan/pulley on the pump pulls air through it. There is an automatic water drain after the radiator. The temp drop is huge from inlet to outlet and so far it seems to do it's job. I get very little moisture from the tank now. I have 50' of 3/4" copper to make a condensing cooler but I'm not sure it will make a lot of difference. We'll see this summer as I use it more. I used this video as a guide but my hardware and tube size is different.
