3.2 4 Stage Automatic Condensate Drain System
3.2.1
Description
The automatic condensate drain system operates electropneumatically and is comprised of the following:
An electrically controlled solenoid valve.
An electrical timer
Two pneumatically operated condensate drain valves
A condensate manifold
A condensate separator/silencer
A condensate collector bottle
The automatic condensate drain system drains the intermediate separators 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 separators at shutdown of the compressor unit.
