Moisture Purge Systems

SSI offers two types of moisture purge systems:
- 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.
- 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.
