Intelligent Automatic Fire Extinguishing Unit (HFC-227ea)

1. System Overview

The Intelligent Automatic Fire Extinguishing Unit is a dedicated fire protection solution specifically designed for CNC machine tools, machining centers, and industrial automated equipment. The system continuously monitors high-risk areas inside the machine tool enclosure and automatically activates fire suppression at the early stage of a fire, rapidly controlling the fire source and effectively preventing fire spread and equipment damage.

The system is widely used in metal processing, automotive manufacturing, aerospace, and precision manufacturing industries. It is a mature and reliable equipment-level automatic fire suppression solution internationally, particularly suitable for unmanned and continuous production environments.

The system uses carbon dioxide (CO₂) as the extinguishing agent. Carbon dioxide fire suppression systems are internationally recognized and are especially effective for extinguishing flammable liquid fires, flammable gas fires, and electrical fires.

The system employs HFC‑227ea (heptafluoropropane) as the extinguishing agent. HFC‑227ea is a highly efficient and clean gaseous suppression agent that suppresses fire through a combined physical and chemical inhibition mechanism. Its chemical formula is CF₃CHFCF₃. It is chemically stable, has very low toxicity, leaves no residue after discharge, is non‑conductive, and will not damage sensitive electronic equipment.

2. Key Advantages

1. Designed specifically for machine tool fire risks

The system provides targeted protection against typical machine tool fire hazards such as cutting fluids, lubricating oils, high-temperature cutting processes, and electrical faults, delivering direct and efficient fire suppression.

2. Rapid response at the incipient fire stage

The system activates automatically when flames or abnormal high temperatures are detected, controlling the fire at its earliest stage and minimizing equipment damage and production downtime.

3. Automatic operation with no manual intervention required

The system can operate independently or be interlocked with the machine tool control system, making it ideal for unmanned or night-time continuous production operations.

4. Clean extinguishing agent, equipment-friendly

The gaseous extinguishing agent leaves no residue, is non-conductive, and does not affect precision machine tools or machining accuracy.

5. Compact structure with flexible installation

The modular design allows the system to be integrated directly inside the machine enclosure or adjacent spaces without affecting normal equipment operation.

6. High reliability and low maintenance

Mechanical or semi-mechanical actuation methods provide resistance to oil contamination and vibration, making the system suitable for harsh industrial environments with low maintenance requirements.

3. Operating Principle

1. The system remains in continuous monitoring mode, supervising high-risk areas inside the machine tool enclosure.

2. Upon detection of flame, abnormal temperature, or hazardous conditions, the system is immediately activated.

3. The fire suppression device automatically releases the extinguishing agent directly onto the fire source.

4. The extinguishing agent suppresses the fire through oxygen displacement, cooling, and interruption of the combustion process, achieving rapid fire extinguishment.
