1 Inlet flows are established in accordance with ISO 7183(based on 1 bar (abs) 0% of at 7 bar (g) working pressure and inlet temperature 35°C (PDP -40°) or inlet temperature 30°C PDP -70°C
2 Average Purge Flow is the total amount of air used to purge and repressurize off-stream towers averaged over the cycle time. Maximum Purge Flow is the flow rate through the off-stream tower during that portion of the cycle the purge/ repressurization valve is open.
