DMA/AF Variable Geometry Attemporator

Brand: Fisher
The Fisher DMA/AF is a variable-geometry, mechanically atomized, back-pressure-activated insertion style desuperheater with on or many spray nozzles. 

It is designed for applications requiring control over moderate load fluctuations and high thermal cycling.
Features
  • Optimized spray pattern with optional AF nozzle technology allows for a wide operating range to achieve optimal mixing and quick vaporization at all flowing conditions.
  • Nozzles can be easily removed, maintained, or replaced without having to replace the entire unit.
  • Piping configuration limits face-to-face availability.
  • DMA and DMA/AF desuperheaters can be located wherever is convenient in the pipeline.
  • Nozzles capable of providing low to moderate amounts of spray-water to cool steam to required temperature.
