Retrofit of a piped-type heptafluoropropane fire suppression system

The project involves customized retrofitting of high‑value communication equipment, employing a piped‑network heptafluoropropane fire‑extinguishing system specifically designed for large‑area protection. Heptafluoropropane is colorless, odorless, non‑conductive, and leaves no residue; it can suppress electrical fires within 10 seconds, ensuring zero damage to sensitive equipment. Its modular piping layout accommodates the complex geometry of server rooms, while seamlessly integrating dual early‑warning systems—temperature and smoke sensors—to eliminate the risk of accidental discharge. Following the upgrade, the system combines high‑efficiency fire suppression with environmentally friendly characteristics (ODP = 0), raising the enterprise’s fire‑safety standards and safeguarding operational stability and continuity.
