Are there any threads here of building a refrigerated air dryer using a mini fridge/freezer?
I have a fridge. Sam’s Club has a freezer for few hundred.
Little dorm fridge, the cooling happes in the little freezer portion at the top, lines run up the back.
40’ of 1/2 copper turbing coiled inside the fridge. Drill two holes in the side of the fridge, one for air in, the other for air out - air in is a higher hole, out is lower. Install drip leg on the output with a drain valve.

I just googled “mini fridge air dryer”……piles of Youtube videos of people who have done just that……
I made one from a mini fridge. Toughest part was trying to find where NOT to drill holes that would go through the cooling lines. I put about 20 feet of copper tube coiled inside the fridge. Really takes any remaining water out of the compressed air… after the transmission cooler on the compressor. I haven’t changed silicon drying beads in a year or more. I run the fridge at about medium cooling on the dial… and only start it up about an hour before cutting… in the warmer weather. $30 for the used fridge. Great investment.
