Description

Marine HFC-227ea Fire Suppression System

1. Scope of Application

The Marine HFC-227ea Fire Suppression System is designed to combat the following types of fires:

  • Electrical Fires
  • Liquid Fires or Fires Involving Meltable Solids
  • Surface Fires on Solids

This system is primarily used in areas on board ships that are prone to fire, such as engine rooms, boiler rooms, battery rooms, and electrical equipment compartments.

2. Features

The Marine HFC-227ea Fire Suppression System is a fully integrated fire protection device that features a pipeline network. Key characteristics include:

  • Comprehensive functionality
  • Reliable and accurate operation
  • Good sealing performance

The system offers three modes of operation: pneumatic, electrical, and emergency manual control.

4. System Components and Working Principle

4.1 Components The HFC-227ea Fire Suppression System consists of the following key components:

  • Cylinders
  • Cylinder Valves
  • Discharge Hoses
  • One-Way Liquid Valve
  • Collection Pipes
  • Pneumatic Control Valves
  • Remote Discharge Stations
  • Pipeline and Nozzles
  • Electrical Alarm Boxes
  • Visual and Audio Alarms

The system can be activated using either pneumatic or electrical methods, with emergency manual control as a backup.

4.2 Working Principle

The system operates by releasing HFC-227ea, a clean, efficient fire extinguishing agent, to suppress fires. The release can be triggered through either pneumatic or electrical means, ensuring the system is versatile and responsive. Once activated, the system discharges the fire suppressant via strategically placed nozzles, targeting the source of the fire with high precision.

5. HFC-227ea Cylinders

The HFC-227ea cylinders are pressure vessels designed to store the fire extinguishing agent. These cylinders are available in various volumes and are engineered for high performance under pressure.
