Admin

Fire suppression systems are playing an increasingly vital role in protecting assets and people, especially in spaces that demand a high level of safety, such as server rooms, data centers, or document storage facilities. Among modern solutions, the FM200 nozzle stands out due to its ability to quickly extinguish fires without harming equipment or the environment. So, what makes the FM200 nozzle the optimal choice for fire suppression systems? Let’s explore this in detail in the following article!

FM200 Nozzle

What is the FM200 Nozzle?

The FM200 nozzle is a critical component of the FM200 fire suppression system, utilizing FM200 gas (HFC-227ea) to extinguish fires. Upon detecting a fire, this nozzle releases FM200 gas, a special type of gas capable of reducing oxygen concentration in the air, interrupting the combustion reaction, and rapidly cooling the fire.

Structure and Components

The FM200 nozzle is a relatively simple device, but it plays a crucial role in the fire suppression system. Its main purpose is to distribute FM200 gas evenly and effectively to the fire-affected area.

1. Nozzle Body:

Material:

Made of stainless steel or brass to ensure high durability, heat resistance, and corrosion protection. Some high-end models have a protective coating to enhance longevity.

Function:
This component directly bears the pressure from the FM200 gas that is transported through the system. It is fixed onto the piping and plays the role of dispersing the gas.

2. Nozzle Holes:

Design:

Several small holes are drilled around the body of the nozzle, arranged in a circular or directional pattern depending on the spray type (360° or 180°). The size and number of holes are calculated to distribute the gas evenly and efficiently.

Function:

It sprays the FM200 gas into the air as fine particles, creating a uniform coverage in the fire area.

3. Connection Threads:

Material:

Typically made to match the nozzle body, with standard threads for easy installation into the system's piping.

Size:

Common sizes: 1/2 inch, 3/4 inch, 1 inch, etc., depending on the fire suppression system.

Classification of FM200 Nozzles Based on Structure

• 360° Nozzle (Full Coverage):
  The spray holes are arranged around the nozzle body, ensuring gas is distributed evenly in all directions. These are typically installed in the center of an open space.
• 180° Nozzle (Half Coverage):
  The spray holes are concentrated on one side, suitable for installation near walls or corners of a room.

Operation Principle

Activating the Fire Suppression System:
The FM200 fire suppression system is integrated with fire detection devices such as heat sensors, smoke detectors, or an automatic fire alarm system. When a fire is detected, the signal from these devices triggers the discharge valve on the FM200 gas cylinder. The gas is then pushed through the piping system under high pressure and ready to be sprayed through the nozzles to quickly extinguish the fire.

Distributing Gas Through the Nozzle:
The FM200 nozzle is designed with specialized spray holes or nozzles to effectively disperse the gas. The gas from the cylinder is directed to the nozzle and is released as fine droplets. Depending on the design, the nozzle can distribute the gas in either a 360° or 180° direction, ensuring the gas covers the protected area, including hard-to-reach spots.

Extinguishing the Fire:
FM200 extinguishes the fire through two main mechanisms:

First, the gas absorbs heat from the fire, lowering the temperature below the combustion threshold, preventing the flames from spreading.

Second, FM200 interferes with the chemical chain reaction of the fire, preventing the combination of oxygen with the fuel. The significant advantage of FM200 is that it does not lower oxygen levels in the air, ensuring safety for people within the protected area.

Completing the Fire Suppression Process:
After the FM200 gas is released and the fire is extinguished, the gas leaves no residue or residue on surfaces. This helps protect electronic devices and assets in the area. However, ventilation should be carried out to remove any residual gas before returning to normal operations in the fire-affected area.

Reasons to Choose FM200 Nozzles for Fire Protection Systems

High Fire Suppression Efficiency

FM200 nozzles are designed to evenly distribute the gas, with two types: 360° or 180° spray, ensuring rapid coverage of the entire protected area. FM200 gas can extinguish fires in just a few seconds after activation, especially effective against fires caused by flammable liquids, electronic devices, or chemical substances.

Safety for People

Unlike other fire suppression gases like CO2, FM200 does not reduce the oxygen level in the air. This ensures the safety of individuals present in the area when the fire suppression system is activated, especially in confined spaces such as server rooms or data centers.

No Harm to Equipment and Assets

FM200 gas leaves no residue or particles after being released, preventing damage to sensitive electronic devices, machinery, or valuable assets in the area. This is why FM200 nozzles are commonly used in data storage rooms, computer rooms, or areas containing critical equipment.

Environmentally Friendly

FM200 is certified as a clean gas, causing no harm to the ozone layer and having minimal environmental impact. Using FM200 nozzles not only protects assets but also helps reduce the negative impact on the ecosystem.

Flexible Design and Easy Installation

FM200 nozzles come in various types with designs suitable for different installation locations, from open spaces to narrow wall corners. The gas piping and nozzle system can be easily integrated into existing fire protection systems, reducing installation and maintenance costs.

Compliance with International Standards

FM200 nozzles and the FM200 fire suppression system meet international safety and quality standards such as NFPA (National Fire Protection Association), ensuring effectiveness and reliability in any situation.
