ABSTRACT:
Apparatus for humidifying a gas stream comprises a transparent reservoir having a top cap and connected via a float controlled valve chamber beneath to a humidifying chamber. The valve maintains a desired water level in the humidification chamber which has a heated floor and gas inlet and outlet ports in its top. Gas flowing between the ports is humidified to a figure approaching 80% and has its temperature raised to a higher temperature than is required at a point of use. The humidified gas flows through a hose which controls the cooling of the humidified gas so that 100% saturation cannot occur until the gas reaches the outlet of the delivery hose at the point of use. The temperatures of the hose and humidification chamber are separately controlled by their own control loops. The float chamber, reservoir and humidification chamber are made of the transparent material and the float and humidification chambers share a common metallic base which is readily detachable for cleaning.
