Fisher DSA Steam Conditioning Desuperheater
BRAND : Fisher
Fisher™ DMA, DMA-AF, DMA-AF-HTC, DSA, and DVI Desuperheaters
Fisher DMA, DMA-AF, DMA-AF-HTC, DSA, and DVI desuperheaters can be used in many applications to efficiently reduce the temperature of superheated steam to the desired set point. Available variations are mechanically atomized (both fixed geometry and variable geometry) and steam assisted. Desuperheaters are available for installation in steam lines from DN25 through DN1500 (NPS 1 through 60) in diameter and are capable of maintaining steam temperatures to within 6C (10F) of saturation temperatures.

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
