3.2 Three Stage Automatic Condensate Drain System
3.2.1 Description
The automatic condensate drain system operates electropneumatically and is comprised of the follow-
ing:
• An electrically controlled solenoid valve.
• A pneumatically operated condensate drain valve
• A condensate manifold
• A condensate collection system
The automatic condensate drain system drains the intermediate separator and the oil and water separa-
tor every 15 minutes during operation. Additionally the automatic condensate drain system unloads the
compressor during the starting phase and drains these filters at shutdown of the compressor unit.
