Moisture Purge Systems

SSI offers two types of moisture purge systems:

  1. The most common type of purge is an airlift.   We make these out of small diameter pipe, starting with a dip tube into a submerged manifold, and rising to just above the water surface. A butterfly valve can be opened to drain the piping system.
  2. The other type is a continuous purge, which is a diffuser installed at the invert of the submerged pipe.  It can be a fine or coarse bubble diffuser.   This kind of purge is often used on retrievable grids or where an an airlift purge valve is inaccessible.
