A drying apparatus 10 for drying gas is provided in which an annular regenerative rotor 16 is mounted for rotation about an axis. The rotor is provided with separate drying and regenerative zones each with a respective inlet 22, 34 and outlet 28, 48. The inlet for the regenerative zone is such that it may either draw regenerative gas from the incoming air stream of the air to be dried or from a separate condenser 56 by coupling means 70 which simultaneously break the connection to the incoming air stream at 34 (Figures 4 and 5, not shown). The arrangement permits the same apparatus to be used where exhaust to atmosphere of regenerative gas is not possible or practical. <IMAGE> |
