I would go for an air dryer, besaus air becomes by compression cold. A dryer also will eleminate tha water in the air.
Slight correction...air when is compressed it becomes hot. Thats how its able to hold so much moisture.
@Jack_the_dentureman If your compressor doesnt have an after cooler, you need do drop the air temp somehow before going into most refrigerated dryers, or get one specific for a hot air supply. An after cooler could be as simple as a long air hose, suspended above the level of the compressor with no drooping low spots...like a snake attached to the ceiling. The air will cool, moisture will condense and drip back down through the hose into your tank. You will need an auto drain set up on your tank. Desiccant dryers like youve shown are a real pain. Those arent auto-recharging, so you would need to replace the beads at least every couple months. Dry air for milling is so important.Its not just hooking a couple pieces together. Its a system.
You can get by with what youve shown, but its a constant pain. Do it right the first time or youre wasting money. Then you can start another thread wondering why your margins are chipping. Moist air makes Zr dust sticky. When your burs start to wear they will easily collect Zr dust and then they wont cut well. Margins chip and youre losing time and money.
Just to be clear...you need a refrigerated dryer and a desiccant set up similar to what youve shown. Not one or the other.
You could use something like this...
Its a refrigrated dryer that allows a high air temp inlet, and has built in filters.
