Low Pressure CO2 Automatic Fire Extinguishing System Introduction

1. Overview

Low pressure carbon dioxide automatic fire extinguishing system is a fire extinguishing facility with superior performance based on the principle of high pressure carbon dioxide automatic fire extinguishing system.This system combines the traditional fire-extinguishing system technology and refrigeration control technology perfectly, and has many advantages, such as high degree of automation, large stock of extinguishing agent, small area of equipment, low storage pressure, reliable work and high safety.The low-pressure carbon dioxide system developed by our company is the only product that has passed the appraisal of the ministry of public security in China, and is at the international advanced level in technology.

Execution standard: GB19572 "low pressure carbon dioxide fire extinguishing system and components".

2. Application Scope

The system can extinguish class A surface and deep fires, class B flammable liquid fires, class C gas fires and live electrical equipment fires, but it is not suitable for extinguishing class D fires.

Products can be used for melting impregnating tank, tank, rolling mill, printing presses, textile machines, generator set, pulverized coal bin, generator oil immersion tank, transformers, hydraulic equipment, drying equipment, dust removal equipment, cooking stoves, spray paint line, electrical aging between library, computer room, data storage, paper, cotton, food, fur library repository and the cabin of the ship and cargo compartment fire protection etc.

3. Composition

The low-pressure co2 fire-extinguishing system is mainly composed of tank components (including storage tank, safety valve, level meter, pressure gauge, pressure switch and other accessories), maintenance valve, main valve, selection valve, electromagnetic valve, refrigeration unit, control cabinet, nozzle, pipe and pipe accessories, etc.

It has the advantages of reliable operation, safety, convenient operation, installation, operation and maintenance.The system can realize automatic monitoring, display pressure and liquid level continuously, and has the functions of high and low pressure and high and low liquid level automatic alarm, and the refrigerating machine can open and close automatically, and the opening time of main valve and selection valve can be controlled by programming according to the size of the protection zone, so as to achieve the purpose of extinguishing fire economically and reliably.
