Cylinder Type Water Mist Fire Suppression System

 

2025061018594019f15

 

Products Description

 


 

​​​Cylinder Type High Pressure Water Mist Extinguishing System-an efficient, clean, and compact fire suppression solution specifically engineered for fast response and minimal disruption in sensitive or confined environments.
This system leverages pre-pressurized cylinders to deliver high-pressure mist, making it ideal for applications where space, simplicity, and system readiness are critical.

 

Unlike pumped systems that rely on electric or diesel-driven pumps, the cylinder type system stores water and propellant gas-usually nitrogen-in pressurized cylinders. Upon activation, the high-pressure gas forces the water through specialized mist nozzles, creating ultra-fine droplets that suppress fires rapidly and efficiently.

The Water Mist Fire Suppression System is an advanced firefighting solution that utilizes ultra-fine water droplets to effectively control and extinguish fires. Its design minimizes water usage while maximizing heat absorption and oxygen displacement, making it ideal for sensitive environments like museums and data centers. With its versatility in combating various fire classes and reduced risk of water damage, this system offers an efficient and environmentally friendly approach to fire safety.

 

Reduced Water Usage: Uses significantly less water compared to traditional systems.

Minimal Damage: Lower risk of water damage to sensitive equipment or materials.

Versatility: Effective on various types of fires, including Class A (ordinary combustibles), Class B (flammable liquids), and even Class C (electrical) fires.

Environmental Impact: Often considered more environmentally friendly due to reduced water consumption and potential for using additives.

Water Mist Application 

 

 

 

Why this industry suitable to use Water Mist System?

 

QQ20260204-165615
01 Data Center(Battery room)

Why Use Water Mist: * Minimal Water Damage: Uses up to 90% less water than traditional sprinklers. The ultra-fine mist evaporates instantly upon contact with heat, preventing "pooling" water from frying adjacent healthy servers.

Smoke Scrubbing: The mist particles actively trap smoke and soot, preventing acidic combustion byproducts from corroding sensitive PCB boards.

02 Diesel Generator Rooms & Turbine Enclosures

Why use Water Mist:

Why Water Mist:

Rapid Cooling: Power generators operate at high temperatures. Water mist has a massive surface area that absorbs heat instantly, preventing structural deformation of the equipment.

Three-Dimensional Suppression: It behaves like a gas (Total Flooding), allowing it to wrap around the complex geometry of an engine or turbine to kill hidden fires.

QQ20260204-170510
03Marine & Cruise Ships (Machinery Spaces/Cabins)

Why Use Water Mist:

Weight & Space Saving: Weight is critical on ships. Water mist systems use significantly smaller tanks and pipes compared to heavy deluge systems, increasing the ship's fuel efficiency.

Continuous Supply: Unlike gas systems (which only have one "shot"), a pump-based water mist system can run as long as there is water, providing endless protection at sea.

04 Underground CableTunnels

Why Use Water Mist:

Flashover Prevention: Cable fires spread fast and hot. Water mist blocks radiant heat transfer, preventing the fire from "jumping" to the next cable tray.

Oxygen Displacement: In the confined space of a tunnel, the rapid expansion of water into steam (1,600x volume) starves the fire of oxygen without the risk of toxic gas buildup.

Water Mist System FAQ

 

Q1: What is water mist fire suppression system?

A water mist fire suppression system is an advanced fire protection solution that uses specialized nozzles to discharge ultra-fine water droplets (less than 100 microns). It cools the fire and displaces oxygen through rapid evaporation.
 

Q2: What is water mist system made of?

It consists of high-pressure stainless steel pipes, water mist nozzles, a power source (pump unit or nitrogen cylinders), filtration systems, and a fire control panel for automatic detection and activation.
 

Q3: What is the difference between water mist and FM200 systems?

Water mist uses pure water for cooling and is eco-friendly; FM200 (HFC-227ea) is a clean agent gas system that suppresses fire chemically. Water mist is better for cooling, while FM200 is ideal for electronic "clean" environments with zero moisture.
 

Q4: How fast does a water mist system suppress fire?

A high-pressure water mist system typically suppresses fire within 10 to 30 seconds of activation, significantly faster than traditional sprinklers due to its rapid heat absorption and "steam" smothering effect.
 

Q5: Where are water mist fire suppression systems commonly used?

They are widely used in Data Centers, Generator Rooms, Museums, Heritage Buildings, Hotels, and Marine/Offshore platforms where water damage must be minimized.
 

Q6: How is the required water mist quantity calculated?

The quantity is calculated based on the protected area volume (m^3), fire hazard class, and nozzle K-factor, following NFPA 750 or EN 14972 hydraulic calculation standards to ensure effective concentration.
 

Q7: What standards do water mist systems comply with?

Reliable systems comply with international standards such as NFPA 750, VdS, FM 5560, and CE (EN 14972) to ensure safety, performance, and hardware reliability.

 

Q8: How do I choose between cylinder type water mist and pump water mist system?

Choose Cylinder Type (Gas-driven) for small, independent rooms (e.g., small server rooms) for easy installation. Choose Pump Type (Motor/Diesel) for large-scale buildings or multiple zones requiring continuous water supply.
