I have something slightly different I'm gong to try, however it may take a while to get around to it since I've got some other higher priority things. I had to replace the outside unit of our heat pump this winter and I had the HVAC guy leave me the old unit. I plan to re-plumb the condensing coils and use them for an air dryer. Looks like on the hot gas side a 1/2 in copper line branches out to 10-12 lines of 1/4 inch tubing. On the other side I can remove the asmaller liquid tubing and re-plumb it to the same 10-12 1/4 inch lines branched to a 1/2 inch pipe arrangement.
