Graham fabricates custom Venturi and Steam-Atomizing Desuperheaters for industries such as power, refining, pulp and paper, food and beverages, plastics, and pharmaceuticals. All our desuperheaters are custom built for each specific application, ensuring trouble-free service for years.

Our Desuperheaters are "in-line" units with flanged, buttweld, or NPT connections, shipped fully assembled and ready for immediate installation. In addition to the company's ISO-9000 quality program, our desuperheaters can be stamped for ASME pressure vessel standards or fabricated to ANSI piping standards.

Graham Venturi Desuperheaters, which use a venturi nozzle to atomize the cooling water, are available in two styles: Double-Venturi (SV-1) and Single-Venturi (SV-2). The SV-1 is our most common style, with a venturi spray nozzle inside a venturi pipe. This style is capable of moderate turndown up to 10:1, low outlet superheat, and moderate pressure drop. The SV-2 is a scaled-down version of the SV-1, with only a venturi nozzle installed in a standard pipe. Turndown capability is much lower at 3:1 and outlet superheat is higher, but this style induces no pressure drop.

Our Steam-Atomizing (SA) Desuperheaters use high pressure steam to atomize the cooling water. Turndown can be very high, up to 50:1, outlet superheat is low, and pressure drop is negligible.

Advantages of Graham Desuperheaters:

  • Range of maximum turndown ratios
  • Minimal pressure drop
  • Compact designs
  • Design code compliant
  • Range of outlet superheat capabilities
  • Variety of standard materials
  • Horizontal or vertical orientation with upward flow
