  • Heat of compression dryer
    Patent number: 6375722
    Abstract: A system for drying a gas includes a source of gas, a compressor connected to the source, and a heat of compression dryer connected to the compressor. The dryer includes a first tower and a second tower, each tower containing desiccant material therein. Temperature monitors are provided at the inlet of the dryer and at the outlet of the towers. Temperature readings from the temperature monitors are communicated to a controller which determines a suitable mode in which the dryer is to be placed.

  • Regenerative compressed air/gas dryer
    Patent number: 6171377
    Abstract: A system for drying a gas, such as air, includes a source of gas to be dried, a multi-stage compressor having an inlet connected to the source, and a dryer connected interstage to the compressor and to the outlet of the compressor. The dryer is connected interstage to the compressor between a compression stage and a heat exchanger of one of the compressor stages for regenerating a first desiccant filled tower. The dryer is also connected to the outlet of the compressor for drying the gas using a second desiccant filled tower. A communication structure can be activated to connect the first tower to the outlet of the compressor for drying the gas using the first tower, and to connect the second tower interstage to the compressor for regeneration of the second tower.
