CO₂ Fire Suppression Systems
CO₂ Fire Suppression Systems – DHP / IHP Series
The Orbis® DHP and IHP CO₂ Fire Suppression Systems are engineered to deliver fast, effective fire protection for electrical enclosures, machinery spaces, and other high-risk environments.
Using carbon dioxide (CO₂) as the extinguishing agent, these systems suppress fires by displacing oxygen around the ignition source — rapidly stopping combustion without leaving residue.
CO₂ is a proven clean agent for non-occupied enclosures, offering unmatched efficiency where traditional methods are not suitable.
How It Works
- Fire Detection
DHP systems detect heat through a pressurized polymer tube installed around risk areas.
IHP systems can detect through the same tube or via connected heat, smoke, or gas sensors.
- Activation
When exposed to high heat, the detection line bursts, or the control panel activates the solenoid valve.
- Agent Discharge
CO₂ is released instantly through discharge hoses and nozzles (IHP) or directly from the detection tube (DHP).
- Suppression
Oxygen is displaced, cutting off the fire’s ability to sustain combustion.
- Reset
- Cylinders are easily refilled, and detection tubing is replaced for continued protection.
System Overview
The Orbis® DHP (Direct High Pressure) and IHP (Indirect High Pressure) systems use high-pressure CO₂ cylinders that discharge the agent either:
Directly, through a heat-sensitive detection tube that ruptures at the fire’s origin (DHP mode).
Indirectly, through nozzles and discharge hoses, activated via heat detection tubing, electronic control panel, or manual release (IHP mode).
Both configurations deliver rapid, targeted suppression while maintaining simplicity, reliability, and minimal installation requirements.
