Electrical Fire suppression system
A tube-based electrical fire suppression system is a type of automatic fire suppression system designed specifically to detect and extinguish fires in electrical enclosures or other small, enclosed areas (like control panels, server cabinets, or switchgear).
How It Works:
The system typically uses a flexible detection tube that is routed inside or around the electrical panel or cabinet. Here's how it operates:
- Fire Detection:
- The tube is pressurized and made of a material (usually a polymer) that ruptures when exposed to high heat—typically in the range of 100°C to 180°C.
- When a fire starts, the rising heat causes the tube to burst at the hottest point, effectively acting as both a sensor and discharge nozzle.
- The tube is pressurized and made of a material (usually a polymer) that ruptures when exposed to high heat—typically in the range of 100°C to 180°C.
- Fire Suppression: Once the tube bursts, it releases a clean agent (such as FM-200, Novec 1230, CO₂, or dry chemical powder) directly at the source of the fire.
- These agents are non-conductive, leave no residue, and are safe for use around electronics.
- These agents are non-conductive, leave no residue, and are safe for use around electronics.
- Immediate Response:
- The localized nature of the system means it responds quickly, minimizing damage and downtime.
Advantages:
- No electricity required to operate
- Quick detection and suppression at the fire’s origin
- Low maintenance
- Compact and easy to retrofit
- Minimizes collateral damage
Kitchen fire suppression system
A tube-based kitchen fire suppression system is an automatic, self-contained fire protection system designed to suppress fires that typically occur in commercial or residential kitchen hoods, ducts, and cooking appliances.
It uses a flexible detection and discharge tube that detects heat and releases a special wet chemical agent to extinguish fires quickly and safely.
How It Works (Kitchen Application):
- Detection Tube Installation:
- A polymer detection tube is routed inside the kitchen hood or over cooking appliances.
- The tube is pressurized and constantly monitors for heat.
- A polymer detection tube is routed inside the kitchen hood or over cooking appliances.
- Fire Detection:
- If a fire starts (e.g., grease fire), the heat causes the tube to rupture at the hottest point (typically 170°C to 180°C).
- This acts as a trigger, either releasing the suppression agent directly from the burst point or activating a separate cylinder via pressure drop.
- If a fire starts (e.g., grease fire), the heat causes the tube to rupture at the hottest point (typically 170°C to 180°C).
- Agent Discharge:
- The system releases a wet chemical agent (e.g., potassium acetate-based) that:
- Rapidly cools the flames.
- Forms a soapy layer (saponification) over hot oil or grease to prevent reignition.
- Rapidly cools the flames.
- The system releases a wet chemical agent (e.g., potassium acetate-based) that:
- Optional Gas Shutoff:
- Many systems include an optional automatic gas shutoff valve to cut off the fuel source when the system activates.

- Hot chips/sparks
- Flammable coolants/lubricants
- High-speed spindles and motors
How It Works (Tube-Based CNC Fire Suppression):
- Detection Tube Installation:
- A flexible polymer detection tube is installed inside the CNC enclosure, above high-risk areas (e.g., spindle, coolant lines, electrical compartments).
- The tube is pressurized and acts as both a sensor and discharge line.
- A flexible polymer detection tube is installed inside the CNC enclosure, above high-risk areas (e.g., spindle, coolant lines, electrical compartments).
- Fire Detection:
- When a fire occurs, rising heat (typically 170°C–180°C) causes the tube to rupture at the hottest point.
- This triggers immediate agent discharge at the fire’s origin.
- When a fire occurs, rising heat (typically 170°C–180°C) causes the tube to rupture at the hottest point.
- Agent Discharge:
- A clean agent (like Novec 1230 or FM-200) is released either:
- Directly from the rupture point, or
- Through nozzles, if the system uses the tube only as a detection mechanism (indirect system).
- Directly from the rupture point, or
- The agent suppresses the fire without damaging sensitive electronics or leaving residue.
- A clean agent (like Novec 1230 or FM-200) is released either:

Fume Hood fire suppression system
A tube-based fire suppression system for a fume hood is an automatic, self-activating system designed to detect and suppress fires directly inside the fume hood workspace. These systems are ideal for laboratories, pharmaceutical environments, and chemical processing areas, where fires may start due to flammable substances or reactions during experiments.
How It Works (Tube-Based Fume Hood Fire Suppression):
- Detection Tube Placement:
- A flexible, heat-sensitive polymer detection tube is routed inside the fume hood sash area, directly above or around the work zone.
- The tube is pressurized and serves as both a detection sensor and discharge mechanism.
- A flexible, heat-sensitive polymer detection tube is routed inside the fume hood sash area, directly above or around the work zone.
- Fire Detection:
- If a fire breaks out (e.g. due to volatile chemicals or a burner), the heat causes the tube to rupture at the hottest point.
- This triggers immediate release of the suppression agent, either:
- Directly through the burst point (direct system), or
- Through fixed nozzles, activated via pressure loss (indirect system).
- Directly through the burst point (direct system), or
- If a fire breaks out (e.g. due to volatile chemicals or a burner), the heat causes the tube to rupture at the hottest point.
- Suppression Agent Discharge:
- A clean or chemical agent is released to quickly suppress the fire and prevent it from spreading or reigniting.
- The system is typically non-electric, allowing for fail-safe operation during power outages.
- A clean or chemical agent is released to quickly suppress the fire and prevent it from spreading or reigniting.
