Water Mitigation
The next battle is to remove as much moisture from the air system as possible. I made a grid cooler that I hung from the ceiling of the shop.
The inlet to the grid is at the upper right and the airflow is downhill, A water trap is located at the bottom outlet of the grid. The tubing length in the grid is roughly 16 feet. The nearby ceiling fan used during the hotter months actually blows a little air across the grid. The water trap is a self draining device. The only thing one needs to remember is to not park anything under the trap. I discovered this issue when I first installed the grid and had left my tooling cart for the mill right underneath. Fortunately no damage other than a bruised ego occurred. This grid was built about 2 years prior to the big air compressor addition and has worked very well. I have never found any water in the lines of any amount since the installation. When I powder coat or use the plasma cutter I have a portable micron filter/dryer that is connected inline depending on the device being used. I am using the Motor Guard M60
I built another grid when I installed the big compressor and it mounts on the wall behind and to the left of the compressor in its outdoor location. Inlet is at the top once again. This grid does not trap as much water due to it being out in the heat with the compressor as well as its close proximity to the compressor. This grid was constructed from 3/4" copper.
The last step was to make draining the water form the tank easy! I purchased a 110V air solenoid and installed it in the tank drain tube. The solenoid plugs into another of the Insteon modules and is controlled by the remote kept in the shop. Plans down the road are to program the ISY automation controller to turn on the solenoid for 5 seconds or so every hour the compressor relay is turned on. For now I just cycle the solenoid with the remote, no need to go outside to manually open a valve.
