Abstract
An adsorption dryer includes first and second drying towers. Each tower has a first port and a second port through which gas can pass into or out of the tower. A first and a second manifold are connected respectively to the first and the second ports of both towers. The manifolds each include integral gas passages, each port of the towers being in communication with a gas passage. Each of the manifolds includes at least one integral valve seat upon which a valve actuator is mounted to constitute a valve to control flow of gas through the gas passages.

An adsorption dryer comprising a first and a second drying tower each of said towers having a first port and a second port through which gas can pass into or out of the tower;
- a first manifold and a second manifold connected respectively to the first and the second ports of both towers, the manifolds each being constructed as a respective casting or moulding, and each manifold including integral gas passages, each port of each of the towers being in communication with an integral gas passage, and the manifolds each including at least one integral valve seat upon which a valve actuator is mounted to constitute a valve for controlling flow of gas through said gas passages, at least one of the valves being a three-port 2/2 valve which, in an open condition, permits passage of gas between all three of its ports and which, in a second condition, inhibits flow of gas through one of its ports while allowing passage of gas between the other two of its ports.
