Fusible Link Sprinkler Heads are automatic fire sprinkler heads that use a fusible alloy as a temperature-sensing element. Like conventional glass bulb sprinkler heads, they are the core fire control and extinguishing component in automatic sprinkler systems. Their key feature is that they trigger their operation based on the melting temperature of the fusible alloy, making them suitable for specific environments or locations with special requirements for temperature sensing elements.

Fusible Link Sprinkler Heads

Fusible Link Sprinkler Heads are automatic fire sprinkler

heads that use a fusible alloy as a temperature-sensing

element. Like conventional glass bulb sprinkler heads,

they are the core fire control and extinguishing component

in automatic sprinkler systems. Their key feature is that

they trigger their operation based on the melting

temperature of the fusible alloy, making them suitable for

specific environments or locations with special

requirements for temperature sensing elements.

Core Basis for Warehouse Sprinkler Selection

》》》

High temperature sensing accuracy: The melting point of the fusible alloy is strictly controlled by the formula, and the error is usually ≤±3℃, ensuring reliable operation at the set temperature;

》》》

High mechanical strength: The alloy element is a solid metal structure, and its vibration and collision resistance are far better than glass balls (glass balls are easily broken by impact), making it suitable for places with mechanical vibration;

》》》

Strong environmental adaptability: Some alloy materials (such as corrosion-resistant alloys) can withstand humid, dusty, and slightly corrosive environments (such as food processing workshops and dusty warehouses)

》》》

Response characteristics: Depending on the design, it can be divided into "standard response" (RTI≥80 (m・s)^0.5) and "fast response" (RTI≤50 (m・s)^0.5) to meet the needs of scenarios with different fire spread speeds

Products Features

Low-melting-point alloy (solid state)

In the solid state, low-melting-point alloys exhibit stable physical properties with melting points typically below 300°C. They maintain fixed shapes at room temperature, featuring good ductility and thermal conductivity. This state allows them to integrate well with other materials, suitable for scenarios requiring temporary fixation or shape retention, such as mold filling and component positioning.

Excellent (no liquid medium)

Relatively high (complex alloy processing)

Places with vibration, high temperature, or concealed installation

Application Industries & Scenarios

4 KEY APPLICATIONS FOR NONFIR FM SPRINKLERS

Installation Tip: The Nonfir FM Sprinkler is engineered for high-performance fire suppression

in a wide range of environments, ensuring rapid response and compliance with FM Global standards.

Automatic Sprinkler Systems

Installed as part of fire protection systems, the Nonfir FM Sprinkler ensures reliable fire suppression during emergencies. Its quick activation and efficient water distribution make it ideal for commercial, industrial, and residential buildings.

Fire Safety in Industrial Facilities

FM-certified sprinklers are widely used in factories, warehouses, and manufacturing plants where the risk of fire is high. These sprinklers are connected to a robust piping system and use high-pressure water sources like fire pumps to ensure fast activation and effective suppression in critical areas.

High-Rise Buildings and Hospitals

For high-rise buildings or hospitals, Nonfir FM Sprinklers are installed to protect stairwells, corridors, and mechanical rooms. These sprinklers are often connected to the main fire protection network, including pressurized water tanks or dedicated fire pumps, ensuring continuous and reliable operation during a fire emergency.

Industrial Fire Protection

In industries like petrochemical plants and power stations, Nonfir FM Sprinklers deliver dependable fire protection. Their durable design and FM certification make them ideal for high-risk environments where reliable fire suppression is critical for worker safety and property protection.
