TABLE 1 – INLET & PURGE FLOWS @ 100 PSIG
|Model||INLET FLOW RATING1
1 Inlet flows are established in accordance with CAGI (Compressed Air and Gas Institute) standard ADF-200, Dual Stage Regenerative Desiccant Compressed Air Dryers – Methods for Testing and Rating. Conditions for rating dryers are: inlet pressure – 100 psig (7 kg/cm2); inlet temperature – saturated at 100°F (38°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.
TABLE 2 – INLET & PURGE FLOW CORRECTION FACTORS
CAPACITY CORRECTION FACTORS
- To determine maximum inlet flow at inlet pressures other than 100 psig (7 kg/cm2), multiply inlet flow from Table 1 by multiplier A from Table 2 that corresponds to system pressure at inlet of dryer.
- To determine purge flow at inlet pressures other than 100 psig (7 kg/cm2), multiply purge flow at 100 psig (7 kg/cm2), from Table 1 by multiplier B from Table 2 that corresponds to system pressure at inlet of dryer.
- To determine outlet flow capacity, subtract purge flow from inlet flow.
