Pipe Network Heptafluoropropane(HFC-227ea) Fire Extinguishing System Introduction

Product features:

Clean and liquid storage at normal temperature

Less than 10% of concentration and harmless to human body

Extinguishing without fouling and fast dissipation

Chemical way to extinguish fire, high efficiency

Applicable object：

Clean room, Computer control room, Precision instrument, Museums, Libraries, Communication equipment, Electrical machinery and power equipment, Chemical raw materials and oil products place

System composition：

The Fire Extinguishing system is mainly composed of extinguishing agent bottle group, container valve, driving gas bottle group, electromagnetic drive device, selection valve, check valve, collecting pipe, safety valve, low leakage high sealing valve, signal feedback device, bottle rack, the nozzle, piping system and other equipment. 

According to the use requirements, various forms such as a unit independent system, a combination distribution system, and no pipe network cabinet type device may be formed, and fire protection for a single zone or multiple zones can be implemented.

Working principle：

Total flooding fire extinguishing system

During a specified period of time, heptafluoropropane is injected into the protected area at a certain concentration, and it is evenly filled in the protected area. The heptafluoropropane fire extinguishing equipment is used to extinguish the fire by total flooding mode. 

Unit independent system

A set of fire extinguishing agent storage device corresponds to a set of network system to protect the composition of a protection zone. According to needs, it can be divided into a single bottle group independent system and a multiple bottle group independent system.
