Product Description
PRODUCT INTRODUCTION
Application Scenarios
Electrical & Data Centers
Ideal for server rooms, data storage facilities, and switchgear cabinets. The perfluorohexanone/nitrogen or heptafluoropropane/nitrogen blends extinguish fires rapidly without conducting electricity or leaving residues, preventing secondary damage to sensitive IT equipment and avoiding costly downtime.
Precision Manufacturing Facilities
Suitable for workshops producing electronics, semiconductors, or precision machinery. These non-corrosive, clean agents protect expensive production lines (e.g., PCB assembly stations) from fire damage while ensuring no contamination to workpieces or production environments.
Historical Buildings & Cultural Heritage Sites
Applied in museums, libraries, and ancient architecture. The low-ODP (Ozone Depletion Potential) and low-GWP (Global Warming Potential) blends (especially perfluorohexanone-based) safeguard irreplaceable artifacts, books, or wooden structures—extinguishing fires without water damage or chemical residue.

Marine & Transportation
Used in ship engine rooms, aircraft cargo holds, and railway electrical compartments. The seamless steel cylinders' high pressure resistance and compact design fit confined spaces, while the gas blends work effectively in low-oxygen or high-vibration environments, critical for maritime and transit safety.

Power Generation Facilities
Essential for transformer rooms, generator enclosures, and substation control rooms. The agents suppress electrical fires quickly, minimizing risks of power outages and protecting high-voltage equipment from irreversible damage.
Sales Key Points
Superior Fire-Suppression Performance
Both perfluorohexanone + nitrogen and heptafluoropropane + nitrogen blends offer fast flame knockdown (within seconds) and long-lasting fire prevention, meeting global standards
