DMA Mechanically Atomized Desuperheater

Brand: Fisher
Request Information
The Fisher DMA desuperheater is a simple, mechanically atomized desuperheater with single or multiple, fixed-geometry spray nozzles and is intended for applications with nearly constant loads. 

The DMA is installed through a flanged connection on the side of a DN 150 (NPS 6) or larger pipeline.
Features
  • Accurate temperature control near saturation. 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.
