A pre-compression dehydration system optimizes the gas flow parameters which are essential to the performance of a radial or spherical desiccant dryer. When used in conjunction with a low pressure dryer, the system protects the desiccant bed from channeling, which can cause the gas to flow...http://www.google.com.au/patents/US5807422?utm_source=gb-gplus-sharePatent US5807422 - Divided radial and spherical desiccant bed adsorption units
