The Turbo Air 3000 Centrifugal Compressor Operator’s Manual
Condensate Drain Piping Option
When this option is purchased at the time of order entry, a piping assembly including a solenoidoperated
drain valve and manually operated bypass gate valve is fabricated and attached to the drain
connection of the intercoolers and aftercoolers. The solenoid-operated drain valves are in turn wired to
the Vantage Control Panel. The Vantage Control System will open and close the drain valves at set
intervals to drain accumulated condensate from the heat exchanger chambers.
The Cooper Turbocompressor design is again compact and very effective. It will save installation cost
and efficiently allow condensate to drain from the cooler chambers without wasting compressed air.

WARNING:
Remember that the outlets of these three drain assemblies must not be manifolded together.
They must individually discharge into an open drain or trough to prevent condensate
from higher-pressure chambers being forced back into lower pressure chambers. This
is the single most common error made at the time of compressor installation.

Pneumatic Condensate Drain Option
Figure A—15 illustrates an alternate to the solenoid-operated drain valve system. The Liquidator TM
Pneumatic Condensate Draining System option is a demand-operated trap that automatically drains
condensate without any loss of compressed air. Significant energy savings could result when using this
system instead of other time-based draining systems. The Liquidator Draining System may be purchased
initially with the compressor or retrofitted later. Request additional information from an authorized
Cooper Turbocompressor representative. Engineering Data Release, EDR-D-005, explains this system and
provides complete installation, operation and maintenance information.
