Blowdown Separator

Model A34-BDS

  • Prevents buildup of harmful solids
  • Reduces boiler scale
  • Uses lash purification
  • For steam boilers
  • Up to 1,600 psig available

Cleaver-Brooks blowdown separators use a safe, economical, flash purification process for enhancing blowdown effectiveness.

Steam is rapidly separated from blowdown water and vented out the top of the blowdown separator in a cyclonic spinning action.

Cleaver-Brooks blowdown separators are compact and can be quickly installed with few connections.


  • Dissolved solids- protects boiler surfaces from severe scaling or corrosion problems
  • Economical flash purification process for enhancing blowdown effectiveness- reduces drain water temperature to meet state and local requirements
  • The design is quiet, with noise levels held below 90 dB, so no exhaust head is required
  • C-B blowdown separators are compact, and can be quickly installed with few connections
  • Stainless steel striking plate greatly extends separator life
  • Momentum of water is speeded by spiral baffle centerwise to drain
  • Drain is completely filled - no center void
  • Trangential inlet and smaller diameter prompt high-velocity spinning for release of steam
  • All interior surfaces slant toward drain, making unit self-draining, self-drying for longer life
  • Available with ASME “U” stamp

Case Study

Properly Treat Boiler Water for Efficient Long-Term Operation

To ensure a boiler runs properly over the course of its lifetime, treating the water that circulates within the system is mandatory. If the water is not treated properly, the boiler will begin to have problems within the first year, and its useful life will be significantly shortened. Boiler symptoms resulting from untreated water include overheating, failure to produce hot water or steam, a drop in the boiler flow rate and an overall loss of efficiency.
