Carraro - Desuperheater VariSpray

VariSpray is a desuperheater with fixed-area nozzles and is used for injecting water droplets into steam via a venturi-shaped section. Along with a combination with a pattern of nozzles, this ensures an excellent and rapid atomization of the injected water

Particularly suitable for low speed vapors so that steam can be thoroughly treated and with a minimum temperature difference of 6 ° C over saturation.

They are primarily intended for low-capacity processes with moderate load changes and where accurate temperature control is important

Primary applications:

  • Turbine Sealing
  • Steam cooling
  • Heat exchangers
  • ejectors
  • Additives for tire vulcanization
  • General purpose such as boilers

Water connection at the top. It is recommended to install a filter (strainer) before the water connection
