8. MISCELLANEOUS DRYER DATA
Capacity Correction Factory
All dryer ratings shown are at 100ºF inlet temperature,
100ºF ambient temperature, 100 PSIG inlet pressure. To
correct for different conditions, use Table A, B, C, and D.
Correction Formula:
New Capacity SCFM = (Cat. Rating SCFM) x (A) x (B) x (C) x
(D)
Example: What is the new rating for a Model 3000 at:
(A) Operating PSI of 100 PSIG
(B) Ambient Temperature of 90ºF.
(C) Inlet air temperature of 110ºF. and
(D) Dew point of 35 - 39ºF
Answer:
(SCFM) = 3000 x (1) x (1.05) x (.83) x 1 = 2614.5 SCFM
