What is a SEM-safe® high-pressure water mist system?

The SEM-SAFE® high-pressure water mist system is a unique fire fighting system. By forcing water at a high pressure through nozzles, an extremely fine mist is created. Water is supplied via a pump unit. The SEM-SAFE® pump unit can supply all water mist applications.

What is a high pressure water mist system?

High-Pressure Systems The AquaMist FOG is a high-pressure water mist system that operates at 50 to 200 bar to produce droplets of an approximate diameter of 50 µm [21, 92]. This water mist system also has multiple nozzle types suitable for each application and can be either pumped or used with stored pressure cylinders, as shown in Figure 25.

What is a micromist water mist system?

The Micromist system uses relatively short pulses of water to aid in the extinguishment of fires as well as minimize the property damage associated with a continuous discharge. How does NFPA define the various types of water mist systems? According to NFPA 750 7.2, water mist systems can be categorized into:

What is a SEM safe water mist system?

The SEM-SAFE system is a high-pressure water mist system designed to operate at approximately 100 bar of pressure and produce water droplets ranging from 10 to 50 µm in diameter . The general arrangement of this water mist system is shown in Figure 27.

How does the SEM-safe® water mist system work?

SEM-SAFE® water mist system with open nozzles On stand-by, the system has dry piping. This system will activate manually or when sensors have detected heat, smoke or a flame, depending on type and application. The nozzles are grouped in sections and all the nozzles in the activated section will be released.

How does a water mist suppression system work?

Connects to the facility’s water main or local reservoir to provide unlimited discharge of low-pressure water mist suppression via a skid-mounted centrifugal pump. The FM-approved system operates at just 175 psi rather than the 1000-2000 psi on average of high-pressure systems, resulting in lower total cost of ownership.
