Abstract
Apparatus for supplying treatment gas, such as for cooling, heating, wiping or drying is provided by a gas handling unit which has a body portion for receipt and discharge of the gas and a plurality of elongated nozzles which may be (a) rigid nozzles, or (b) flexible nozzles which assume a substantially rigid projecting position when gas is flowing through the nozzle and a collapsed retracted or partially collapsed position when gas is not flowing. The unit may discharge gas in more than one direction. Certain preferred arrangements of nozzles are provided. The nozzles preferably have an inlet portion which is of greater cross-sectional area than the outlet portion and may have an inlet portion which is generally cylindrical cooperating with a generally conical outer discharge portion. In a preferred embodiment, the gas treatment apparatus may be employed in cooling metal coils. An associated method is provided.
