Product Overview of Non-Pressurized Perfluorohexanone Fire Suppression Systems Overview                                                          

I. Product Overview 

The non‑pressurized perfluorohexanone fire‑extinguishing system is a specialized automatic fire‑suppression device designed for battery modules. It consists of an aluminum alloy enclosure, a gas‑generating module, a plug, a thermal‑sensitive wire, and other components. The system is charged with perfluorohexanone extinguishing agent, which is non‑toxic and harmless to lithium batteries, other electrical equipment, and nearby personnel. This device can rapidly and effectively extinguish lithium‑battery fires, thereby preventing more severe damage.

II. Application Areas 

It can be used to extinguish fires in any lithium‑battery module.

III. Product Advantages

Compared with conventional fire‑protection products or solutions, this product offers distinct advantages, specifically manifested in… 

The following aspects:  

Four 、 Product Appearance and Structure 

                                                               Product Features

1. Integrates automatic fire detection and suppression functions into a single system;
2. Automatic activation, with full‑submersion fire suppression within the battery module, completes discharge in under one second, achieving rapid fire extinguishment.

V. Product Composition and Principle 

1. Product Composition

The device primarily consists of an aluminum alloy housing, a gas generator assembly, a plug, a thermosensitive wire, and other components. 

1. Working principle 

When a fire occurs inside the battery module, the flame ignites the module’s… Thermal line (Ignition temperature: 170 °C ±10 °C.) Upon activation, the thermal‑sensitive line triggers the gas‑generating assembly within the lithium‑battery fire‑suppression module. The gas generator rapidly deploys, producing high‑pressure gas that ruptures the module’s outer casing, thereby expelling the perfluorohexanone extinguishing agent contained inside.

It is deployed instantaneously, flooding the entire interior space of the battery module to achieve fire suppression.

Non-Pressurized Perfluorohexanone Fire Suppression System | Frequently Asked Questions

Q1: Which protected areas are suitable for non‑pressurized perfluorohexanone fire suppression systems?

A1: Suitable for enclosed spaces such as precision computer rooms, distribution rooms, energy storage cabinets, and archives; effective for extinguishing electrical fires, but not suitable for fires involving reactive metals or strong oxidizers.

Q2: What is a non‑pressurized type?

A2: The device does not store high pressure within its cylinder; instead, it relies on an initiating gas‑generating assembly to propel the extinguishing agent. This eliminates the need for high‑pressure cylinders, resulting in enhanced safety during transportation and storage.

Q3: What startup methods are available for the device?

A3: Supports temperature‑controlled automatic start-up and electrically interlocked activation of the fire alarm system, and can be equipped with a mechanical emergency start to comply with fire safety codes.

Q4: Will the discharge of perfluorohexanone damage precision equipment?

A4: The agent is clean and leaves no residue, exhibits excellent insulation properties, and does not corrode precision electronic components after discharge. Following fire suppression and ventilation, equipment can be quickly restored to service.

Q5: How long is the shelf life of the medication, and do the cylinders require regular hydrostatic pressure testing?

A5: The formulation exhibits excellent stability; the container can be stored at ambient pressure, eliminating the need for periodic hydrostatic testing required for pressurized cylinders—maintenance and replacement are sufficient based on the product’s service life.

Q6: Will gaps in the protected area affect the fire suppression performance?

A6: Yes. During fire suppression, the doors, windows, and ventilation openings of the protected area must be closed to minimize agent loss, maintain the design extinguishing concentration, and ensure effective fire suppression.

Q7: During the system’s discharge delay phase, may personnel remain inside the protected area?

A7: No. Personnel must evacuate the protected area within the delay period, and entry is prohibited after discharge to prevent inhalation of the agent’s vapors.

Q8: Can the perfluorohexanone agent be disassembled, reassembled, and refilled independently?

A8: No. Refilling and maintenance of the fire‑extinguishing agent must be performed by a qualified fire‑protection contractor; unauthorized disassembly or reassembly may render the system inoperative.

Q9: Can a single system protect multiple protected zones?

A9: It can be used in conjunction with piping networks and selection valves to provide protection for multiple zones; when no selection valve is installed, it can only protect a single protected zone.

Q10: What routine maintenance checks should be performed?

A10: Regularly inspect the enclosure for damage and ensure wiring is intact; check the status of the starting components. Conduct system testing annually by a qualified maintenance provider.
