Step by Step Operation
1. Detection or Release Input
The ILP system is configured to respond through one or more actuation pathways depending on project requirements. Typical release methods include:
• heat-sensitive detection tubing
• smoke or gas detection through a releasing/control panel
• manual release station actuation
2. Release Signal Initiates Valve Operation
When the initiating condition is met, the ILP valve assembly is actuated pneumatically, electrically, or manually, depending on the system configuration. This opens the cylinder for discharge.
3. Agent Is Routed Through the Discharge Network
Unlike direct systems, the extinguishing agent is not discharged through the detection tube. The agent is routed from the cylinder through dedicated discharge lines to fixed nozzles installed within the protected enclosure.
4. Nozzles Distribute Agent Within the Hazard
The nozzle network distributes the suppression media across the protected enclosure, allowing broader and more controlled coverage for larger or more complex assets.
5. Fire Is Automatically Suppressed
The released agent suppresses the fire within the enclosure while helping reduce damage escalation, downtime, and spread to adjacent components. This architecture is suited to cabinets and enclosed systems where a single direct discharge point is not sufficient.

Applications

Electrical Cabinets & Control Panels
Protects against electrical faults, short circuits, and overheating. Installs directly inside panels to automatically suppress fires before they spread, minimizing downtime and equipment loss.

Industrial Machinery & CNC Machines
Prevents costly fire damage from overheated motors, lubricants, or electrical malfunctions. Compact systems fit inside machinery housings and enclosures, offering rapid, localized suppression.

Battery Enclosures & Energy Storage
Addresses fire hazards caused by thermal runaway, electrical faults, and overheating in battery systems. Ensures fast-acting protection for lithium-ion or lead-acid battery cabinets.

Transportation Infrastructure
Safeguards vehicles, generators, and mobile equipment from engine fires, fuel leaks, and electrical shorts. Ideal for buses, trucks, mining vehicles, and critical backup power systems.

Telecom Cabinets & Outdoor Enclosures
Provides round-the-clock protection for remote telecom, data, and power enclosures, especially in unmanned or harsh environments where response time is critical.

Chemical Storage & Flammable Liquid Cabinets
Controls fires resulting from spills, leaks, or ignition of stored chemicals and solvents. Compatible with cabinets for paints, thinners, and cleaning agents.
