Advanced Direct Low-Pressure Fire Suppression
The Orbis® Direct Low-Pressure (DLP) Fire Suppression System provides rapid, automatic fire protection by detecting and suppressing fires at their source. Engineered for precision and efficiency, our DLP system ensures reliable fire suppression in electrical panels, enclosures, CNC machines, and other critical equipment. With its direct-release mechanism, it swiftly extinguishes fires before they escalate, minimizing downtime and damage.
Benefits
- Zero downtime during installation
- No electrical connections needed
- Simple retrofit for existing enclosures
- Reduces insurance and compliance risk
- No messy clean-up after discharge
- Cost Effective
How the Orbis® DLP System Works
The DLP system utilizes a specially designed heat-sensitive detection tube that is pressurized with a clean agent. The tube is routed throughout the protected enclosure and continuously monitors for fire. When a fire occurs, the intense heat causes the tube to rupture at the hottest point, instantly releasing the suppression agent directly onto the flames. This targeted discharge quickly cools and extinguishes the fire, preventing its spread and reducing collateral damage.
Technical Features
- Heat-sensitive detection tube covers all fire-prone areas
- Instant agent release at the fire’s hottest point
- Rapid discharge quickly cools and controls the fire
- Prevents spread to other equipment or compartments
- Monitors enclosure 24/7 for fire events
- Safe for use with energized electrical panels
Step-By-Step Operation
- Detection
A flexible, heat-sensitive detection tube is installed inside the enclosure, positioned near potential fire hazards.
The pressurized tube continuously monitors for temperature increases and acts as both a fire detector and suppressant delivery system.
- Activation
- If a fire ignites within the enclosure, the heat from the flames rapidly increase the temperature of the surrounding area.
At the hottest point, the detection tube ruptures due to the extreme heat.
- Suppression
The rupture in the tube releases the clean agent directly onto the fire.
The agent cools the flames, swiftly extinguishing the fire.
- Reset & Maintenance
- After activation, the system requires refilling and resetting to ensure continued protection.
Regular maintenance ensures optimal functionality and reliability.
Applications
