I've had my air operated diaphragm pumps "ice" up from time to time on really busy days. After a lot of research, I thought I'd share an Intercooler that I've added to my compressor. Unlike a tank drain, the moisture is removed BEFORE it enters the tank. You see, hot air can hold much more moisture than cool air, therefore the trick is to cool the humid, hot, and moist air thereby causing the water to condense out.
I purchased a racing transmission cooler online for about $100. The hot compressed air enters the cooler at the top and the cooler air exits the bottom. FWIW, I've checked the air going in at 240 degrees F, and it exits at about 4 degrees above ambient.....approximately 75 degrees. A Rotron fan (Used on ebay about $35) pushes air across the heat exchanger. An moisture separating air filter is placed in the exit line between the heat exchanger and the tank. Mine has an automatic "dump" so the whole operation operates "unattended".
It's amazing how much water this setup removes. I've had no problems with "icing" since.
