How does the Dv0.99 affect the system performance?

The water mist extinguishing mechanism is two fold.

  • Removal of heat energy from the fire plume due to vaporization of mist into steam. The large surface area per unit volume inherent in smaller droplets results in a very efficient and rapid heat transfer process.
  • Localized displacement of oxygen from the fire base due to the production of steam. When water changes into steam, it expands by a factor of 1650 times which results in oxygen displacement in the immediate fire area.

The SECURIPLEX Low Pressure (FIRE-SCOPE® 2000) and High Pressure (FIRE-SCOPE® 5000) produce a water mist with droplets in the Dv0.99 range of 200 microns.
