3.2 Three Stage Automatic Condensate Drain System
3.2.1 Description
The automatic condensate drain is an optional system and may not be included with your unit.
The automatic condensate drain system operates electropneumatically and is comprised of the following:
An electrically controlled solenoid valve An electrical timer
A pneumatically operated condensate drain valve A condensate manifold
A condensate collector tank
The automatic condensate drain system drains the intermediate separator and the oil and water separator
every 15 minutes during operation. Additionally the automatic condensate drain system unloads the com-
pressor during the starting phase and drains these filters at shutdown of the compressor unit.
