Home Made Air Dryer Idea

[Complete_Loser]

This Air Dryer forum doesnt have an option for "New Topic" so i will just post here for now.

I have an idea for an air dryer. But not sure if it will work.
I was thinking of getting an A/C window unit and plumbing my copper airline into its cooling radiator. And down stream have an auto water blow off valve.

This would be much cheaper than me buying a refer air dryer, yet would be the same concept (i think).

Too much plumbing and provisions for venting the hot exhaust.

Small refrigerators are cheap - dormroom size.
Run your air into a spool of copper tubing inside the unit. All it would take is a couple of quick-disconnects running to the outside of the unit and a long coil of tubing. Put a water seperator at the outlet and plug it in.

One idea I found...........pretty nice actually, as long as you don't mind buying ice.....could act as a beer cooler simultaneously....

Yes, this concept works!!!!!!!!!!! Check out my post titled cheap homebrew air dryer. The copper tubing is more eficient than the plastic line I used but, the plastic seems to work fine. I have not had a drop of water in my lines since installing it. I used the plastic because I already had a bunch of it lying around and i was looking to prove the concept on the cheap.

As for the air conditioner idea, it would use alot more power and be harder to fabricate than using a fridge.

How much copper tubing would you need to put in the frig for it to work. Where I work we coil bundle for small hot water heaters. I could get a pretty big copper coil drill some holes the frig and pipe it up and be all set to go.

Would i need to put a filter on the airline to help out.

I think it works best if the coils were looped horizontally instead of vertically, like itsnotlevel has shown. I've seen quite a few built with the loops at 90 degrees to his.

With the verticle, moisture is being trapped at the bottom of each loop. With a top-down horizontal design, the moisture would all drain down by gravity.

Just a suggestion.
