I did hydro test. The term hydro implies water. I used a pressure washer to get up to the necessary pressure. Hydro tests are safer if vessel ruptures plus it's easy to get pressure needed with pressure washers.
Didn't need to. The velocities in the small tubing I used will easily push water droplets out to the air dryer which has a separator with auto drain. The few droplets that might exist after the compressor shuts off will be stuck in the bends.
It's a high temperature (750F) high pressure (750#) hose off Amazon that minimizes the vibrations on the air cooler. I originally had copper tubing in this spot but decided to switch to flex hose.
I should also mention that Derale states the MAWP for this exchanger on their website (250psi) which makes me feel much better. Many coolers have no rating.

I really don't think there is any oil. My first thought was to simply install a separator, but they all seem to be filter separators and most of them have regulators built in which I don't need or want. Makes me feel like I am the only guy out there doing this.......
I'd like to just send all...
I'd like to add a filter separator before the dryer just in case there is any oil, etc but every filter separator I look at has like just a few ounces of capacity. You'd think it would be easy to find one with maybe a 1/2 gallon or so but nope. I guess I could put a auto drain on it. Here is one...
The test was performed with water hence the term "hydro". 1.2x would have been fine but I just wanted a little more safety factor and went all the way to 1.5x. I am putting the tank up high on a wall out of the way and don't look forward to doing this test again anytime soon. I have picked out...
I'm installing an Emax 5hp 80 gallon unit in my garage along with their refrigeration dryer. I don't want to run the dryer all the time which is what will happen if I simply plug it in. I thought about tying the dryer to my light circuit or maybe a countdown switch or flow switch but I think...
