n: a tray, installed in an absorber tower or fractionating column, that is similar to a bubble-cap tray, except that it has only holes but no bubble caps through it. This type of tray is more efficient than the bubblecap tray or the valve tray and less expensive than either;however, it does not operate properly over a wide range of flow rates.
