FAQ for 5.6 MPa Stored-Pressure Type Heptafluoropropane Fire Suppression Systems

Q: What types of facilities are suitable for an internally pressurized 5.6 MPa heptafluoropropane fire suppression system?

A: Suitable for small and medium-sized protected areas such as computer rooms, distribution rooms, archives, and energy storage compartments; capable of extinguishing Class A, B, and C fires, as well as energized electrical fires.

Q: What are the differences between internal‑pressure 5.6 MPa and 4.2 MPa heptafluoropropane systems?

A: The rated storage pressure differs; at 5.6 MPa, the pressure is higher, allowing a cylinder of the same volume to be filled with a greater quantity of agent, enabling longer delivery distances and imposing stricter requirements on the pressure rating of the piping system.

Q: What startup methods does the system support?

A: It features three activation modes—automatic, manual, and mechanical emergency—and can be connected to a fire alarm control panel. The agent discharge is triggered by the interlock of smoke and heat detectors.

Q: What does 5.6 MPa signify?

A: Refers to the extinguishing agent and the driving nitrogen coexisting within the cylinder, with a rated storage pressure of 5.6 MPa at the specified temperature, which serves as the design storage pressure parameter for this system model.

Q: What are the key considerations for system installation and construction?

A: The cylinder assembly is installed in a dedicated cylinder room, with nozzles arranged appropriately and piping subjected to pressure testing in accordance with relevant standards. Proper sealing of the piping ensures uniform distribution of the extinguishing agent throughout the protected area.

Q: What items should be inspected during routine maintenance?

A: Regularly inspect the cylinder pressure gauge, cylinder valve, and pipeline connections for leaks; test the fire‑alarm interlock devices; and check the cylinder body for rust or deformation.

Q: What effects does the discharge of heptafluoropropane have on personnel within the protected area?

A: Prior to discharge, an audible and visual alarm will be activated, and personnel must evacuate promptly. During the discharge, entry into the protected area is strictly prohibited; access to the site is permitted only after thorough ventilation.

Q: Will the discharged agent damage precision electronic equipment?

A: Heptafluoropropane is a clean agent that leaves no particulate residue and exhibits extremely low corrosivity, making it compatible with sensitive electrical equipment in computer rooms; after extinguishing, simply ventilate the area.

Q: Can the agent be refilled on-site after it has been released?

A: On-site refilling is not permitted. After discharge, the cylinders must be transported back to a qualified fire‑safety organization for inspection, and the extinguishing agent and propellant gas must be recharged.

Q: Does this system meet the acceptance requirements for fire protection projects?

A: The product is accompanied by a fire‑safety inspection report and complies with relevant gas‑extinguishing standards. Upon completion of installation and commissioning, it can be integrated with the protected area to facilitate overall fire‑safety acceptance.
