Selecting an appropriate heptafluoropropane fire suppression system for a specific facility requires consideration of the facility type, spatial characteristics, and fire suppression requirements; such systems are primarily categorized into three types: piped network systems, cabinet-type systems, and suspended systems.

Pipeline network system
This system is suitable for large spaces such as data centers and computer rooms, capable of protecting 1 to 8 protected zones. It delivers extinguishing agent uniformly through a piping network and supports automatic, manual, and mechanical emergency activation modes. It should be noted that the fire-resistance rating of the enclosure structure of the protected zone shall be no less than 0.5 hours, and that of the suspended ceiling shall be no less than 0.25 hours.
Cabinet-type device
Suitable for small to medium-sized spaces, such as switchgear rooms and archives, this system does not require a dedicated cylinder room and can be installed directly within the protected area. The area of a single protected zone should not exceed 500 m², and its volume should not exceed 1,600 m³. Cabinet-type units allow flexible configuration of the number of nozzles (typically 1 to 10) and support rapid response for fire suppression.
Suspension device
Specifically designed for enclosed spaces—such as precision laboratories and cultural-relic storage rooms—this system requires no complex piping network. Upon activation, it fills the protected area within seconds, delivering high extinguishing efficiency with no residual byproducts. It is particularly well suited for applications with stringent post-extinguishment recovery requirements, such as server rooms housing sensitive electronic equipment.
Selection recommendation:
Large, complex facilities (such as data centers and computer rooms): prioritize piped network systems to ensure uniform fire suppression and the ability to protect multiple protected zones.
Small and medium-sized enclosed spaces (such as distribution rooms and archives): cabinet-mounted or suspended units are more cost-effective and practical, with flexible installation and rapid response.
Special scenarios (such as cultural heritage protection sites): Prioritize suspended or pipe-free cabinet-type systems to prevent water stains and corrosive residues.
