Abstract
Keywords: Dryer, compressed air, aluminum evaporator, separation zone, dew point.
This paper presents constructive solutions for aluminum evaporators used in compressed air dryer systems manufactured and tested at RAAL Bistrita, Romania. By the means of theoretical and experimental research the engineers at RAAL developed modern constructive solutions for compressed air dryers. The work was especially conducted towards optimizing the dryers' performance, i.e.: low level humidity of the compressed air (low dew point) and improved efficiency in dew separation.
