Maintain Room Integrity During Gas Discharge
Pressure Relief Dampers (PRDs) are crucial elements in gaseous fire suppression systems, specifically engineered to safeguard enclosures from the risks associated with excessive pressure buildup during system discharge. These dampers play a vital role in maintaining the structural integrity of the enclosure while ensuring the correct concentration of the suppression agent is achieved. This dual function not only enhances the safety of the environment but also optimizes the performance of both clean agent and inert gas systems. PRDs are particularly beneficial in environments such as data centers, switch rooms, control rooms, and battery energy storage facilities, where maintaining operational integrity and safety is paramount.
Why Pressure Relief Dampers Matter
Without proper pressure control, enclosure walls and ceilings can be damaged when gas systems discharge. Pressure Relief Dampers automatically balance air pressure, preventing damage and ensuring system efficiency. They are vital for maintaining the enclosure’s integrity and compliance with international fire protection standards.
Controlled Pressure Release
Allows controlled release of overpressure during fire suppression discharge to preserve enclosure integrity, protecting both structure and sensitive systems.
Prevents Structural Damage
Protects walls, ceilings, and enclosures from excessive internal pressure during gas discharge, ensuring building integrity and occupant safety.
Engineered for Gaseous Systems
Built to withstand high-velocity gas discharge from suppression systems, maintaining optimal pressure control and safety during system operation.

How Pressure Relief Dampers Work
During suppression activation, PRDs automatically open to release excess air pressure, allowing the gas agent to fill the room evenly. After discharge, they close to maintain post-event containment and prevent air ingress that could affect room integrity.
Automatic Pressure Balancing
Automatically opens during fire suppression discharge to balance internal air pressure, preventing enclosure damage and maintaining system integrity throughout activation.
Backflow Prevention
Engineered to block reverse airflow after agent discharge, maintaining sealed system integrity and preventing contamination or re-entry of harmful gases post-event.
