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