Air Dryer for Electrical Enclosures

摘要

An air dryer having an internal orifice (52) designed into an outlet end cap (30) that eliminates the need for external valves or regulators to control the flow of air through the dryer. The internal orifice (52), which can be press-fit or threaded into the end cap, provides a consistent and stable outlet flow and dew- point and eliminates the need for instruments to measure outlet flow and dew point. The orifice size can be easily changed for changing oudet flow and dew point. A protective tubuhir shroud (32) is provided for shielding a membrane module (24) of the dryer, and for routing sweep gas to a bottom vent.
