ELECTRICAL CABINET FIRE PROTECTION
Reacton - Automatic Suppression for Control Panels and Enclosed Electrical Equipment
Reacton systems provide fast, automatic fire suppression directly inside electrical cabinets and enclosures, stopping faults before they escalate into major failures. The system detects heat at the source and activates instantly to stop electrical faults turning into major failures. No power, no electronics, and no downtime from false alarms.
Key Features
Rapid heat-activated response
Clean-agent suppression for electronics
Works with no power or wiring
Ideal for enclosed electrical spaces
Compact and simple to install
Low maintenance
Minimises downtime after an incident
Globally certified technology
How the Reacton System Works
1. Detection tube installed inside the cabinet
A heat-sensitive pneumatic tube is routed around high-risk components within the enclosure. It sees what sensors and smoke detection often miss: heat right at the source.
2. Tube bursts at fire temperature
When exposed to a fast-rising localised fire, the tube ruptures at the closest point to the heat. No power or electronics are required.
3. Automatic clean-agent discharge
The pressure drop triggers the cylinder valve, releasing a clean agent (such as Novec 1230). The agent extinguishes the fire without damaging sensitive electrical equipment.
4. Minimal residue and quick reset
The clean agent leaves almost no residue, allowing systems to be returned to service with minimal disruption.
Typical Applications
Manufacturing plants
Mining sites
Food and beverage facilities
Transport infrastructure
Automation and robotics systems
Power distribution and control
Data and communication networks

vs
Standard Electrical Fire Protection
| Feature | Reacton (Pneumatic Tube) | Traditional Detection Systems |
|---|---|---|
Detection method | Tube directly inside the cabinet | Smoke/heat detectors outside the enclosure |
Activation | Instant at the fire source | Slower, delayed by enclosure seals |
Power required | None | Requires wiring and panels |
Agent type | Clean agent, safe for electronics | Varies, often leaves residue |
False alarms | Very low | Possible in dusty or industrial areas |
Installation | Fast, compact, retrofit friendly | More complex, higher cost |
Best use | Enclosed electrical cabinets | Open areas or large rooms |
Why Choose Reacton
for Electrical Cabinets
Stops fires before they escape the enclosure
Protects mission-critical equipment
Reduces unplanned downtime
Simple annual maintenance
Proven performance in harsh industrial settings
Envirotec supplies, installs and maintains the full Reacton cabinet protection range, backed by trusted clean-agent technology.
Why Electrical Cabinets Need Fire Protection
Electrical panels are one of the most common ignition points in industrial and commercial sites. Loose connections, overloaded circuits and component failures can ignite fast, especially in enclosed spaces with limited airflow.
Reacton protects these critical areas by detecting the fire right where it starts, before it can damage equipment, shut down operations or spread to nearby assets.
Works for:
Control panels
MCC cabinets
Data and comms cabinets
Battery systems
PLC enclosures
CNC and machinery control panels
Switchboards and distribution boards

FAQ
Does Reacton require any power or wiring?
No. It is a fully mechanical system that works even during a power loss.
What type of agent does it use?
A clean agent such as Novec 1230, which is safe for electronics and leaves almost no residue.
Where is the detection tube installed?
Inside the enclosure, routed around the components most likely to fail or overheat.
How often does it need servicing?
Once a year. Maintenance is simple and fast.
Can it be installed in existing panels?
Yes. Reacton systems are compact and ideal for retrofitting.
What happens after activation?
The cylinder is replaced or refilled, and the detection tube is renewed. The cabinet can often be returned to service quickly due to the clean agent.
