Water Mist

---

Watermist systems can be used in a wide variety of applications where gas suppression or traditional sprinklers are not suitable or practical.

Examples of fire protection applications are:

• Diesel Generators
• Food Processing
• Hotels
• Data Centres
• Hospitals
• Care Homes

Water mist systems can be split

into two categories:

• High Pressure Water mist (HPWM)
• Low pressure water mist  (LPWM)

High Pressure Water Mist

High pressure water mist systems HPWM consist of high pressure pumps and storage tanks or cylinders of water and pressurised nitrogen cylinders to discharge the water.The installation is carried out utilising small bore stainless steel pipe work and high pressure discharge nozzles.

They use only minimal quantities of water and are more expensive to install than low pressure watermist systems.

Low Pressure Water Mist

Low pressure water mist systems LPWM consist of pumps and storage tanks, they generally use more water than HPWM systems although significantly less than traditional sprinkler systems.

Due to the lower pressures involved the pipe work installation can be carried out using a variety of different materials such as copper pipe and even specialist plastic pipe work.

Codes of Practice

There are few codes of practice and standards
available at present that offer specific guidelines
on the design and application of watermist.

Therefore it is more important than ever that the
equipment nozzles pumps etc carry the highest
standards of approval and have testing data to support
each application.

For further information on any water mist system please contact your local office.
