Protect Your Electrical Cabinets
Where Risk Begins
Detection ExtinctionSimple and Effective
Electrical fires account for a significant portion of industrial losses. Cabinets are ventilated, open, and rarely sealed.
Direct Detection
At the heart of at-risk components, independent of overall sealing
Immediate Extinction
Targeted distribution of FK-5-1-12, zero residue, no secondary damage
Automatic Cutoff
Immediate safety through power and ventilation shutoff
Reflexofeu does not promise a calculated concentration.It guarantees performance validated under real fire test conditions.

Types of electrical cabinets protected
Our fire detection and suppression system adapts to all industrial and commercial electrical equipment
Main switchboards and low voltage panels
Protection of Main Switchboards (LV switchboards), LV panels, distribution boards and sub-distribution boards. Our system detects abnormal heating near busbars and cuts power before fire can spread.
Sub-distribution boards and secondary panels
Protection of sub-distribution boards, sub-boards and secondary distribution panels. The compact system installs without modifying the existing cabinet, ideal for control panels and electrical enclosures in service.
Server racks, IT cabinets and data centers
Protection of 42U server racks, 42U cabinets, patch panel cabinets, network racks and SAN/NAS enclosures. Localized suppression per IT rack preserves adjacent equipment and ensures business continuity in server rooms and data centers.
Battery cabinets and capacitor banks
Securing battery cabinets, capacitor bank cabinets, PFC cabinets and energy storage cabinets. Early detection from 57°C limits propagation risk in power factor correction systems and UPS cabinets.
Power cabinets and VFD cabinets
Protection of power cabinets, VFD cabinets, drive cabinets and control panels. The system adapts to variable frequency drives, transfer cabinets and emergency power cabinets for immediate safety.
Solar inverter cabinets and wind turbine cabinets
Protection of solar inverter cabinets, stringboxes and wind turbine electrical enclosures in outdoor environments. The system withstands extreme temperatures and adapts to renewable energy installation constraints.
Industrial electrical cabinets IP55/IP65
Protection of IP55 industrial electrical cabinets, IP65 enclosures and C5 cabinets in harsh environments. The detection-suppression system works independently of cabinet airtightness, even with permanent ventilation.
Operating Principle
Industrial electrical enclosures feature permanent ventilation openings, cable penetrations, and technical gaps that make long-term airtightness unrealistic. We therefore adjust the extinguishing agent quantity to compensate for leakage. Fire outbreaks are detected at the ignition source, and a dry contact output is made available after activation to disconnect the main power supply and secure your installations.

Frequently Asked Questions
The lead time is flexible to suit your availability: from next week to several months later, depending on your preferences and your electrical power supply shutdown constraints.
FK-5-1-12 falls within the broad regulatory definition of PFAS currently under review in Europe, like the vast majority of fluorinated gases on the market. This restriction proposal, examined by ECHA, has not yet been voted on or implemented, and no decision is expected before 2027 at the earliest. Unlike historically targeted substances (PFOA, PFOS), FK-5-1-12 does not exhibit persistent, bioaccumulative, and toxic properties, and has undergone REACH toxicological assessments concluding the safety of its use. Clean agent extinguishing agents also benefit from long-term exemptions (over 10 years) envisaged in the proposal, due to the lack of an equivalent alternative. Reflexofeu ensures continuous regulatory monitoring and will adapt its systems in line with legislative developments.
The cost of a Reflexofeu system typically ranges between €1,300 and €1,600 per unit. The exact price depends on the volume of the electrical cabinet to be protected and is subject to a customized quote tailored to your installation. Excluding installation.
Yes, after a discharge, the system must be recharged and repressurized. The detection tube or bulb must also be replaced if it was damaged during the discharge. This restart is organized directly with our teams, who will carry out the necessary inspections and restore your installation to working order.
Reflexofeu systems have a service life of 10 years, in accordance with the Pressure Equipment Directive. This service life may be reduced depending on the environment present in the plant.
As the manufacturer and installer, we carry out maintenance on your systems every year. An inspection report is sent to you annually.
No, FK-5-1-12 does not reduce the oxygen level inside the cabinet to extinguish the fire. It works by absorbing the activation energy.
Yes, we offer a dedicated system that relays the information wirelessly by SMS or email. You can watch the informational video about the Kheiron system in the INFO section.
Yes, we provide a dry contact or several dry contacts that let you relay the system's trigger signal. They can also be used to cut the electrical power supply after extinguishing via an MX or MN shunt trip coil.
We fit out existing cabinets on site, new or old, adapting the solution to the cabinet based on its configuration and internal equipment. We also take into account the volume and ventilation openings...
Reflexofeu systems were specifically designed to protect this type of equipment. Reflexofeu is the first system certified under the NTN 128-L standard by the ANPI laboratory. This certification verifies extinguishing performance on electrical cabinets and IT servers.
Yes, the system is designed to trigger as close as possible to the source of the fire, minimizing damage inside the electrical cabinet and allowing production to restart quickly.
No, there is no damage following activation of the Reflexofeu system. No corrosion, no cleanup, and no residue.
Yes, the extinguishing agent is effective on live electrical fires. It is in fact recommended for this use, as it is dielectric up to 30,000 volts.
The FK-5-1-12 extinguishing agent. It has been recommended for over 20 years for electrical fires. It is dielectric up to 30,000 volts and leaves no residue. It does not damage the components inside the electrical cabinet or IT server.
Yes. The system works with no external power supply at all. This has always been a design requirement. Trigger relay, operation, and siren activation also work without any external power supply.
Our systems use 100% physical detection and triggering: a detection tube that heats up and bursts, or a UL-certified sprinkler bulb that triggers at a given temperature. False activations observed to date have been caused by: - technical work on the cabinet that pierced the detection tube - the presence of rodents
During laboratory tests and real fire tests, the measured extinguishing time has always been under 3 seconds. You can consult the ANPI test report in the INFO section.
There are 2 detection modes: - A pressurized tube (Reflexotube) placed as close as possible to the components, which bursts in the event of overheating of a faulty electrical component or on contact with the first flame. - A thermal-trigger sprinkler head, positioned at the top of the volume to be protected, which triggers according to the bulb used at 57, 68, 79, 93, or 141°C.
Not all electrical cabinets carry the same level of risk. Criteria for assessing criticality can include the consequences of a production shutdown, the equipment's condition and age, electrical load, environment, accessibility, and more. The weight given to each criterion depends on your business. We have developed a criticality matrix that lets you score your cabinets and establish a clear order of priority. Contact us to get the matrix free of charge.
