Title: The Benefits Of Specifying Microdrop High Pressure Water Mist
1The Benefits Of Specifying Microdrop High
Pressure Water Mist
2Water Mist A Definition
Water mist is defined as a water spray for which
the 99 of the flow-weighted cumulative
volumetric distribution of water droplets,
Dv0.99, is less than 1000 microns. This Value is
found at the minimum design operating pressure
and is measured in a plane 1M from the nozzle.
3Droplet Size Significance
- Greater Surface Area
- Evaporate Quickly
- Remain Airborne Longer
- As a consequence
- Enhanced Performance
- Attenuate Radiant Heat
- Improved Smoke Scrubbing
- Smaller Footprint
4The Intelligent Use of Water
- 335kJ to heat 1 litre from 20oC to 100oC
- 2257kJ to convert 1 litre to steam
- 16201 volumetric expansion
MicroDrop Heat Absorption Capacity Is Higher Than
Any Gaseous Suppression System Agent

6Fire Test Plastic Waste
Highly Effective Cooling
- Controls the fire
- Reduces radiant heat
Oxygen Displacement
- Steam generation aids extinguishing
- Characteristic is unique to HPWM
7Safe for People SNAP Listed
U.S. Environmental Protection Agency A Medical
Health Panel evaluated water mist under the
Significant New Alternatives Policy (SNAP). The
panel concluded that water mist using potable
water is benign to nature and does not present a
toxicological or physiological hazard to human
beings and is thus safe for use in occupied
areas.
8Key Advantages
- Low Water Usage
- Minimises Consequential Damage
- Reduces Waste Water Volume Bund Size
- Less Intrusive Installation
- Small Bore Stainless Steel Tube
- Light Weight
- Reduced Installation Time
- High Radiant Heat Attenuation
- Controls Fire Spread
- Reduces Damage
9Performance The Criteria
- Fire Control
- The limitation of the growth of a fire by pre
wetting adjacent combustibles and
controlling ceiling gas temperatures to
prevent structural damage. - Fire Suppression
- The sharp reduction of the rate of heat release
of a fire and the prevention of fire re-growth. - Fire Extinguishment
- The complete suppression of a fire until there
are no burning combustibles.
10Fire Control Suppression Control Examples
- Typical Class A Fires
- Ordinary combustibles
- Deep seated
- Highly shielded fires - i.e. in cabinets
- Low heat release
11Fire Extinguishment Examples
- Typical Class B Fires
- Flammable liquids
- Pool fires
- Spray fires
- High heat Release fires - plastics

24Why Choose TYCO
- We are the worlds largest fire protection system
specialist - Comprehensive technical and financial resources
- Long term commitment to MicroDrop HPWM
- Directly involved in development of mist
technology since 1878 - Efficiencies in the MicroDrop product and
engineering expertise minimise the physical and
environmental footprint - MicroDrop minimises heat and smoke damage to
safeguard both life and property
25Environmental issues
- MicroDrop systems use only naturally occurring
gaseous and hydraulic media e.g.. Water, Nitrogen
- MicroDrop minimises the environmental impact and
damage of fire. - Efficient use of water drastically reduces fire
effluent run off. - MicroDrop efficiencies reduce the quantities of
water and power needed for effective fire
protection. - Mist technology significantly reduces the use of
extracted and processed earth resources i.e.
piping and water. - Strategic location of regional offices
significantly reduces travel miles for both
products and installation teams
