The condensate is fed from the condensate collection line via the condensate inlet [A] into the pressure relief
chamber [1]. In the pressure relief chamber [1], entrained compressed air is separated before the condensate
flows through the FRC [2] into the measuring chamber [3] and then into the filter cartridges [10].
The FRC [2] monitors the filling level in the measuring chamber [3]with the following sensors:
•
High Level Alarm (HLA) sensor
•
High Level (HL) sensor
•
Low Level (LL) sensor
When the filling level in the measuring chamber [3] reaches the High Level (HL) sensor, the condensate is
passed through the filter cartridge [10] with auxiliary air. The FRC [2] will perform a discharge operation with
the following steps:
1. The PISTON solenoid valve is switched.
0 The piston in the FRC [2] is pressurised with auxiliary air and closes the connection to the pressure
relief chamber [1].
2. The PULSE solenoid valve is opened at intervals.
0 Auxiliary air is conveyed into the measuring chamber [3].
3. The auxiliary air introduced displaces the condensate from the measuring chamber [3] and forces the
condensate into the collector [8] through the filter cartridges [10].
is controlled and monitored by the flow regulation
