Transvac has been designing and manufacturing desuperheaters for the power, food, chemical and process industries for over 35 years. Transvac direct-contact desuperheaters typically reduce superheated steam temperatures to within 30°C of the saturation temperature. To cool the superheated steam, a medium (usually water) is entrained and flashed into vapour by absorbing heat from the steam.

The companys desuperheater range includes a venturi desuperheater. It is suitable for constant or variable load handling duties, with turndowns up to 10:1.

Applications

  • Turbine bypass systems on power plants for heat exchangers and dump stations
  • Steam for indirect contact heat exchangers and reactor heating jackets
  • Steam for direct contact heating (food kettles, inline steam heaters, tobacco drying plant and paper mills)

Advantages

  • Low cost
  • No moving parts
  • Minimal steam pressure drop
  • Flexible design options
  • Simple to install

Materials of construction include carbon steel, stainless steel and chrome molybdenum.

Transvac is accredited to BS EN ISO 9001:2000 and certified to module H of the PED.
