In some critical use, air-drying systems, 100% back-up capability is desired. The problem has been that an idle standby unit requires considerable time to reach full capability for dry air delivery. This invention bleeds enough dry air from the operating primary unit through parts of the idle back-up unit to maintain any dynamic conditions that are necessary to keep the standby unit ready for immediate use in the event of a failure of the primary unit.


In a gas-drying system including two dehumidifiers, one of which operates as a primary system and the other of which serves as a standby back-up system, and each of which includes an air dryer unit and each of which constitutes a self-contained system that can supply the full demand for dry gas to a place of use when the other system is not in operation and for indefinite periods of time such as a day or a plurality of successive days, each dehumidifier having means for connecting it with a source of gas, to be dehumidified, the improvement which compris...
