Internally stored pressure heptafluoropropane fire extinguishing system

Product Introduction
The HFC-227ea fire extinguishing system consists of a cylinder rack, extinguishing agent cylinders, propellant gas cylinders, high-pressure hose, liquid check valve, manifold, safety relief device, low-release, high-sealing valve, selector valve, gas check valve, signal feedback device, and electromagnetic drive nozzle.
Features
1. Diverse Models: The system is available in two configurations: standalone and modular. It offers two storage pressures, 4.2 MPa and 5.6 MPa, and is available with various cylinder sizes to meet diverse needs.
2. Compact Design: The system can be arranged in single or double rows, making it compact and adaptable to cylinder rooms of various shapes and sizes.
3. Easy Maintenance: The system features a rational design with key components located within the cylinder room, allowing for quick inspection of each component's status.
4. Quick Assembly: The system utilizes a modular design with a rational structural design, allowing for disassembly and transportation, and rapid on-site assembly.
5. Quick Response: When installed in a cylinder room near the protected area, the system is professionally calculated to rapidly release the extinguishing agent and extinguish the fire.
6. Safety and Reliability: The device features automatic, manual, and mechanical emergency operation modes, ensuring reliable operation and comprehensive safety measures.
7. Cost-Effectiveness: For multiple, large-scale protection areas within close proximity, an internal pressure storage system is more economical and affordable.
8. Genuine Materials: The extinguishing agent is of high purity and is filled according to professional design and calculation.
