Apparatus is provided which controls humidity in a gas. The apparatus employs a porous interface that is preferably a manifolded array of stainless steel tubes through whose porous surface water vapor can pass. One side of the porous interface is in contact with water and the opposing side is in contact with gas whose humidity is being controlled. Water vapor is emitted from the porous surface of the tubing into the gas when the gas is being humidified, and water vapor is removed from the gas through the porous surfaces when the gas is being dehumidified. The temperature of the porous interface relative to the gas temperature determines whether humidification or dehumidification is being carried out. The humidity in the gas is sensed and compared to the set point humidity. The water temperature, and consequently the porous interface temperature, are automatically controlled in response to changes in the gas humidity level above or below the set point. Any deviation from the set point humidity is thus corrected.

A manifolded porous tube array for humidification and dehumidification of a gas comprising in combination: (a) a pair of spaced, opposed elastomeric sealing gasket plates, each plate having an inside face and an outside face and perimeter portions; (b) a plurality of porous tubes arrayed in spaced relationship to one another, each one of said tubes having exterior circumferential surface portions and a pair of opposite ends, said exterior surface portions that are adjacent each said opposite end of each said tube being slidably but sealingly positioned in a different respective one of said gasket plates; (c) a pair of manifold means, each one being sealingly associated with said perimeter portions and generally enclosing said outside face of a different one of each of said gasket plates with all said tube ends that are so positioned in each gasket plate communicating with a generally fluid tight manifold chamber that is defined by the combination of the adjacent one of said manifold means and the associated said gasket plate, each one of said manifold means further including hole means for conduit association so that a fluid is circulatable from said hole means of one of said manifold means through said tubes to said hole means of the other of said manifold means; and (d) spanner means which circumscribes said tube plurality and which has longitudinally opposite ends that are each associated with a different one of said manifold means so that a chamber is defined by said spanner means and said gasket plates through which chamber said tube plurality extends, said spanner means including at least two passageway means which are positioned so that a fluid is circulatable through said chamber from one said passageway means about said exterior circumferential surface portions of said tubes to another of said passageways means.
