Product Overview of Suspended Perfluorohexanone Fire Extinguishing Systems

1 , Overview

1.1 System Overview

Hanging-type perfluorohexanone Gas fire suppression The device consists of a fire-extinguishing agent storage cylinder, Temperature-sensitive release assembly It consists of a signal feedback device, a suspension bracket, and other components. It eliminates the need for fire‑extinguishing agent delivery piping and a dedicated cylinder storage room, and can be installed either suspended or wall‑mounted. In the event of a fire, it directly discharges the extinguishing agent into the protected area, with no pipeline losses, resulting in faster extinguishing and higher efficiency. The system offers both automatic and manual activation modes. 

1.2 Application Areas

Hanging-type fluoropropane Gas fire suppression The device is primarily suitable for the following types of fires: solid‑surface fires; liquid fires; gas fires where the gas supply can be shut off prior to extinguishing; and electrical fires. 

Typical application scenarios: Primarily suitable for Fires in computer rooms, data centers, aviation facilities, ships, vehicles, libraries, and oil and natural gas production sites. It is particularly well suited for confined spaces. The suspended perfluorohexanone gas fire suppression system can be installed as a standalone unit to protect smaller protected areas, or multiple units can be interconnected to safeguard larger spaces.

1.3 Fire extinguishing agent

This device uses perfluorohexanone as the fire‑extinguishing agent. Perfluorohexanone primarily relies on chemical suppression while also providing physical cooling, and it is colorless, odorless, clean, non‑conductive, and non‑corrosive to protected equipment. It does not damage property or sensitive precision instruments and has no adverse impact on the atmospheric ozone layer. ODP The value is zero, meeting environmental protection requirements; in most protected areas, the extinguishing concentration is below the threshold for non‑toxic effects on humans. NOAEL Its concentration is safe for humans, making it an excellent clean-gas fire suppressant.

1.4 Safety Warning

1. When perfluorohexanone is discharged, it generates a condensing aerosol that extinguishes fires by interrupting the combustion chain, achieving rapid fire suppression. If used in occupied areas, clearly visible warning signs must be installed. Suggested wording for such signs is as follows: Warning sign within the protected area: “Warning! Upon hearing the on-site alarm, personnel must evacuate immediately.”
2. In addition to the aforementioned warnings, other safety measures shall comply with the relevant current national regulations.

3 , Startup Method

This device is temperature‑activated: when the temperature in the protected zone reaches the activation threshold of the fire‑extinguishing system, the heat‑sensitive glass bulb within the extinguishing unit ruptures, triggering the thermal release assembly to open and allowing the extinguishing agent to be discharged into the protected area for fire suppression.

5.1 Installation Preparation

Prior to installation, carefully read the relevant instruction manuals and familiarize yourself with the project design plan. Ensure that the layout of this fire suppression system conforms to the design drawings, and that all components are complete and meet the design specifications.

5.2 Installation

1 ) According to the locations indicated on the fire suppression design drawings, secure the mounting brackets to the wall or ceiling using expansion bolts. Ensure that the wall and ceiling are strong enough to support the weight of the equipment.

2 ) Install the pressure gauge onto the container valve port and tighten it with a wrench. Using a wrench, unscrew the nut behind the pressure gauge counterclockwise until the gauge registers; if the pointer is in the green zone, this indicates normal operation. Then, use the wrench to tighten the nut clockwise.

3 ) Connect the assembly, equipped with the pressure gauge and pressure transmitter, to the suspension bracket using bolts.

4 ) Inspect all installation and connection points to ensure secure fastening, proper sealing at pipe joints, and correct wiring. At this stage, the entire suspended perfluorohexanone fire suppression system has been fully installed.

Hanging-type Perfluorohexanone Fire Extinguishing System | Frequently Asked Questions

Q1: What types of facilities are suitable for suspended-type perfluorohexanone fire suppression systems?

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

Q2: What are the characteristics of a suspended-type perfluorohexanone fire suppression system?

A2: The unit is suspended and installed at the top of the protected area, requiring no piping network. It is easy to install, occupies minimal space, and, upon detection of a fire, directly discharges the extinguishing agent downward.

Q3: What startup methods does the device support?

A3: Equipped with temperature‑controlled, thermally activated automatic start-up; it can also be connected to a fire alarm system for electrical interlock activation. Some models feature mechanical emergency start-up.

Q4: Will the discharge of perfluorohexanone extinguishing agent damage precision electronic equipment?

A4: The agent is clean and leaves no residue, exhibits excellent insulation properties, does not corrode components, and allows equipment to be quickly put back into service after ventilation.

Q5: How long is the shelf life of the medication, and does the container need to undergo a hydrostatic pressure test?

A5: The pharmaceutical agent exhibits chemical stability; pressure‑type cylinders undergo regular hydrostatic testing in accordance with applicable standards, while non‑pressure‑type cylinders do not require cylinder hydrostatic testing and should have their components replaced according to the product’s service life.

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

A6: Yes. Before discharge, ventilation openings, doors, and windows should be closed to minimize agent loss and ensure that the design extinguishing concentration is achieved within the protected area.

Q7: During the system startup delay phase, can personnel remain within the protected area?

A7: No, personnel must evacuate 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 of fire‑extinguishing agents and equipment maintenance must be performed by a qualified fire‑protection contractor; unauthorized operations may render the system inoperable.

Q9: Can a single suspended-type perfluorohexanone system protect multiple rooms?

A9: Conventional suspended pipeless systems can protect only a single protected space per unit; multiple rooms require multiple units.

Q10: What routine maintenance checks should be performed?

A10: Regularly inspect the securement of the equipment suspension, check for any damage to the enclosure, and verify the condition of the pressure gauge; have the entire system inspected annually by a qualified maintenance provider.
