When checking the Kobelco unit this afternoon, I found there was a standing puddle of water (~1/4in deep) on the right side (looking at control screen) of the enclosure. Moving to the back side it was found to be a leak in the aftercooler auto drain line, right at the isolation ball valve. There was a continuous spray of water coming from the threads on the upstream side of the ball valve.
The dewpoint at the drying towers was still -81C, same value as this morning, so it did not cause any issues downstream of the compressed air line. The drained water was simply collecting in the bottom of the enclosure instead of flowing out of the drain line.
There was no in-chamber work happening at HAM1 at the time of discovery so after a phone call with Gerardo, I shut down the compressor unit and isolated the air line between the compressor and the receiving tank. I then closed the purge air inlet valve at the HAM1 chamber.
There is currently no purge air going to the LVEA.
Kobelco unit
The compressor remains off, the new leak, a coolant leak was found at a ball valve, and it needs to be fixed. We have contacted the vendor and are awaiting on a response.
HAM1 Update
HAM1 remains closed for business until further notice, or a work around can be established.
Caution, watch out for volume on your device, lots of noise present on attached video.

A tech from Roger's Machinery came out to the the site today to diagnose the issue. It was indeed the ball valve on the aftercooler drain line, the valve body had cracked right through the threads. He swapped the ball valve and cleaned the water from the bottom of the cabinet.
Compressor was restarted, open to the receiving tank and drying towers, but the purge air outlet valve was not opened. No other issues found, the dewpoint at the drying towers dropped quickly (currently at -56C and still dropping).
There is still no purge air going out to the LVEA/HAM1, the compressor/dry air skid will continue to run over the weekend before opening back up to the LVEA purge air line.

Here is a trend of the dew point from 17:00 Fri 20th Feb through to 09:00 Sun 22nd Feb.
