WarningCO₂ Transcritical
CO2 Multi-Ejector Fault
On ejector-equipped racks the multi-ejector block recovers high-side pressure energy to lift MT suction gas into the receiver, cutting compressor work. A stuck cartridge or control fault kills the efficiency gain and upsets receiver control.
Symptoms
- Ejector cartridges not staging with high-side pressure / load
- MT suction pressure higher than design; poor efficiency in transcritical mode
- Receiver pressure control hunting when ejectors should be active
