Most industrial compressors (IE rotary screw, scroll, rotary vane, etc) have aftercoolers, because the temperature of compression is pretty high.
The aftercooler causes most of the water to condense out.
So what you lose is efficiency, because it will take compressing more intake air to get the same yield of compressed air at a certain pressure/dewpoint.
(this is why you often see a lot of wet storage tanks for air - leaving it in the tank lets a lot of the intake air water condense at the bottom)
Aftercoolers remove a ton of of the water, and so you often get an 20 degree approach temperature.
Removing more than that requires some form of air dryer.
