I have a 7.5 HP Ingersal-Rand system with an automatic drain. It
vents for 2 seconds every hour. Besides keeping the tank bone dry it
has the advantage of scaring the hell out of the cats if they are any
where near by.
Turn the bottom outlet on just a tiny bit. Do this at pressure.
You don't want to drain the tank, but have a nominal leak that
blows water out the bottom.
My pump turns on every 6-7 hours when not using it. If a long time off,
I unplug the pump.
Since doing that, my air has been much dryer and the dryers and active dryer
does the rest.
Just what I am doing.
I've had an upright Sanborn (similar to your C-H) for the past 20 years
and I *never* release the pressure from the tank, at least not unless
I'm draining the water, which isn't all that often. I don't run it
balls-out too often, but when I do moisture in the lines is rarely a
problem because I use one of these:

I've had it for the same 20 years and it works like a champ. WAY better
than those glass bowl filters.
See Nad. See Nad go. Go Nad!
To reply, eat the taco.
Another thing to consider is an auto drain assembly.
It is an enclosed ball and needle vale that drains the tank when ever the
ball float goes above a certain level.
It is piped to the drain valve connection.
I have them on both compressors and they stay nice and dry.
I also use a filter on the line just in case.
Got everything throough Grainger's or McMaster Carr, I don't recall which.
