Airtightness Testing Equipment
The Protected Area Airtightness Testing System is designed to evaluate the airtightness of enclosures within facilities using gas extinguishing systems. This system measures the peak pressure and dwell time inside the protected area to assess the reliability of the system. It also checks whether the Pressure Relief Valve (PRV) opens correctly, ensuring that pressure peaks do not exceed structural limits during testing. The system is compatible with international standards such as GB, ISO 14520, ASTM, NFPA 2001, and EN15004.
Application
The Protected Area Airtightness Testing System is used to verify the airtightness and structural integrity of enclosures in facilities with gas extinguishing systems, including:
Data Centers
Electrical Rooms
Industrial Plants
Critical Areas
