Externally Stored Pressure HFC-227ea Gas Fire Extinguishing System

Suitable for extinguishing the following types of fires:

Electrical fires
Liquid fires or fires involving molten solids
Solid surface fires
Gas fires that require cutting off the gas supply before suppression

PRODUCT DETAILS

Overview

The Externally Stored Pressure (Reserve Pressure) HFC-227ea Fire Extinguishing System consists of extinguishing agent cylinders, driver gas cylinders, high-pressure metal hoses, check valves (for extinguishing agent pipeline), distribution pipes, safety venting devices, selection valves, signal feedback devices, extinguishing agent delivery pipelines, nozzles, driver gas cylinders, electromagnetic drive devices, driver gas pipelines, check valves (for driver gas pipeline), and other components. The transfer distance of the externally stored pressure system is typically no more than 250 meters.

In the Network-based HFC-227ea Fire Extinguishing System, the extinguishing agent storage cylinders are placed in a dedicated cylinder room and connected through a network of pipes. In the event of a fire, the extinguishing agent is transported from the cylinder room to the protected area through the piping system and released through nozzles to suppress the fire. This system is the preferred choice for multi-zone protection in large buildings, capable of protecting up to eight separate zones simultaneously.

Fire Extinguishing Principle

When the fire suppression system is in automatic control mode, and a fire occurs in the protected area, the fire detectors trigger a fire signal. The alarm controller immediately activates both audible and visual alarms. The gas fire control panel receives two independent fire alarm signals and sends out a linkage command to shut off related equipment. After a 30-second delay, the fire extinguishing command is issued, which opens the corresponding solenoid valve to activate the gas. The activation gas flows through the activation pipeline, opening the appropriate selection valve and container valve of the driver gas cylinders. The driver gas then enters the extinguishing agent cylinder group via the pressure-reducing device, simultaneously opening the agent cylinder group’s container valve. The extinguishing agent is then delivered through the piping network to suppress the fire.

Applications

Suitable for extinguishing the following types of fires:

Electrical fires
Liquid fires or fires involving molten solids
Solid surface fires
Gas fires that require cutting off the gas supply before suppression

Ideal for protecting enclosed spaces, including the following typical locations:

Hazardous areas with explosive gases or liquid-type fires
Libraries, archives, document storage rooms, and museums
Oil-immersed transformers, distribution rooms with oil-filled switches, and backup generator rooms
Communication rooms, data centers, and computer rooms
