FIRE-RATED DOORS WITH LOUVERS (FUSIBLE LINK TECHNOLOGY)
Standard ventilation louvers leave a door completely vulnerable to smoke and fire. To solve this, our fire-rated doors are fitted with advanced fusible link louvers. During normal daily operation, the louver blades remain open, allowing air to
circulate freely. However, if a fire breaks out and the ambient temperature reaches a critical threshold (typically 165°F /
74°C), the heat-sensitive link melts. This triggers a heavy-duty spring mechanism that instantly snaps the louver blades
tightly shut, sealing off the room to prevent the spread of fire and toxic smoke
KEY BENEFITS
Automated Fire Defense: Provides standard ventilation daily, but automatically transforms into a sealed fire barrier during an emergency.
Climate & Pressure Control: Allows HVAC systems to operate efficiently by equalizing air pressure between rooms and preventing
stagnant air buildup.
Equipment Cooling: Provides necessary exhaust and intake pathways for heat-generating machinery to operate safely.
IDEAL APPLICATIONS
Mechanical and electrical rooms, boiler and utility closets, generator enclosures, IT server rooms, and industrial manufacturing zones
