Fisher™ DSA Steam Conditioning Desuperheater

The Fisher DSA desuperheater uses high-pressure steam for rapid and complete atomization of spraywater in low velocity steam lines. This desuperheater is installed through a flanged connection on a DN 200 (NPS 8) or larger pipeline. This desuperheater is intended for applications requiring high rangeability.

Key Features

  • Nozzles can be maintained or replaced without having to replace the entire unit.
  • The DSA desuperheater is capable of 40:1 rangeability.
  • DSA desuperheater can be located wherever is convenient in the pipeline.
  • In the DSA desuperheater, high-pressure steam is mixed with the spraywater to produce a critical or near-critical pressure drop in the atomizing steam for a very high velocity. The high velocity disperses the spraywater into very small particles
