J. DESIGN CONDITIONS
Each dryer is shipped complete and ready for installation. Every dryer is tested and preset at the factory for
optimum service at the design conditions. The following are the standard design conditions for a refrigerated dryer
operating at 60 HZ:
38°F (3.3°C) Pressure Dew Point
100°F (37.8°C) Inlet Temperature (Compressed Air)
100 PSIG (7 bar) Compressed Air Pressure in PSI Gauge
100°F (37.8°C) Ambient Temperature (Room Temperature)
SCFM (Model #/min.) Rated Flow in Standard Cubic Feet per Minute.
K. SHUT-DOWN
All dryers may be shutdown by simply turning the operational switch to "OFF." Models D-320-A and larger require
the main power disconnect to remain on unless service or maintenance work is to be performed. They have one
fan motor wired to run to lower head pressures after shut-down.
