Abstract
A cargo or bulk product off-load system includes a compressor ( ) that pressurizes air. The air is dried by a dryer ( ) and routed to a supply tank ( ). From the supply tank, the air is either used to pressurize service reservoirs ( ) or to assist the off-load system. Air stored in the service reservoirs ( ) is used to pressurize purge volumes associated with the dryers ( ). The compressor ( ) operates at a lower pressure when supplying air to assist the off-load system than when pressurizing the service reservoirs ( ). Controllers ( ) coordinate switching of airflow, and alternating purging and drying of the dryers.
