Entrained air being present in any hydronic system can cause a myriad of problems, from cold areas due to the system being air bound, to premature equipment failures due to rust, scale, and corrosion. There are two ways to remove air from the system, by the use of an in-line (air scoop) and by use of a centrifugal type separator. Air separators prolong the life of heating and cooling systems.
A tangential air separator, such as the envirosep E-ASL/ASW, utilizes tangential openings to create a centrifugal action, required to create a vortex at the center of the vessel. Being lighter than water, the air is forced to the center of the vortex and rises to the top opening in the air separator where it is vented to atmosphere or directed to the expansion tank. This type of air separator also allows for a smaller vessel to be utilized than is required for a low velocity type.
The Envirosep in-line air separator operates on the premise that air will rise in the piping and then into the air scoop, being directed to the top opening and out of the system through an air vent or to an expansion tank. Since proper operation of this type of air separator is also dependant on velocity, sizing this type of air separator is a function of proper flow rate. This type of air separation is best suited for residential and light commercial applications.
