WDS Air/Steam Moisture Separator

The WDS Series Separators are used for the removal of entrained liquid or solids from steam or air. Effective in applications where the system has an entrained liquid flow rate of up to 40% by weight of the unit’s flow capacity.

How It Works

Wet steam enters the inlet of the separator where it is deflected in a centrifugal downward motion. The entrained moisture is separated out by reduction in velocity. Separated liquid then falls below the Vortex Containment Plate where it cannot be re-entrained. Dry steam or air then flows upward and exits through the outlet of the separator.

Features

  • Removes 99% of all particles > 10 microns in size
  • Minimum pressure drop
  • Gauge ports on 3” & 4” cast iron units
  • Standard gauge ports on 21/2”–12” carbon steel units
  • ASME Code constructed

Installation and Maintenance
The WDS Air/Steam Moisture Separator must be installed in a horizontal run of pipe. Exercise standard piping and structural practices when installing this unit. Proper drainage of the separator utilizing a float & thermostatic steam trap or liquid drainer (for air applications) is essential for proper operation.
Sample Specification
Steam Moisture Separator shall be “T” style for horizontal piping installations. Separator to be code constructed in cast iron or carbon steel and available in FNPT and flanged connections.
