Abstract
Various embodiments of a heat-exchange dryer apparatus are disclosed. In one embodiment, a heat-exchange dryer apparatus includes a desiccant cartridge comprising desiccant material, a purge-air reservoir secured to the desiccant cartridge, and a compressed-air conduit disposed inside the purge-air reservoir. In another embodiment, a vehicle air-brake system includes an air compressor, a desiccant cartridge comprising desiccant material, and a heat exchange dryer apparatus disposed between the compressor and the desiccant. The temperature of the compressed air is decreased while the temperature of the purge air is increased and the desiccant adsorbs a greater amount of contaminants form the compressed air for improved drying.
