Description
The cooling system comprises air cooler (Ca) and oil cooler (Co).
On air-cooled compressors, the cooling air flow is generated by fan (FN).
2.5 Condensate system
Water drains
Condensate drains, typical example
Reference Designation
Da Automatic drain connection
Da1 Automatic drain connection of the dryer (only on Full-Feature units)
Next to each automatic drain outlet is a manual condensate drain connection for manually draining of the
condensate.
Electronic condensate drains, typical example
The compressors have an electronic water drain (EWD). The condensate from the air cooler accumulates in
a collector. When the condensate reaches a certain level, it is discharged through the automatic drain outlet
(Da).
On Full-Feature compressors, an additional electronic water drain (EWD1) is provided. The condensate
trap of the heat exchanger is drained by EWD1 and discharged through automatic drain outlet (Da1).
Also see section Air flow.
Testing the electronic water drain can be done by briefly pressing the test button (1) on top of the drain.
