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 cyclone drip 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
  • Standard gauge ports on 1-1/2” to 3” cast units
  • Standard gauge ports on 3”–12” fabricated units
  • ASME Code constructed
