In the fire protection of special places such as data centers, power distribution rooms, and cultural relics warehouses, the cabinet type heptafluoropropane fire extinguishing system relies on its; Ready to use, precise protection; Its characteristics make it the preferred solution to ｒｅｐｌａｃｅ traditional pipeline systems. As a national high-tech enterprise, Guangdong Dingya Fire Equipment Co., Ltd. has been deeply involved in the field of gas fire extinguishing for 16 years. Now, it analyzes the core advantages of the cabinet type heptafluoropropane system from the perspectives of technical principles and engineering practice.
| Comparing dimensions | Cabinet system | Traditional pipeline network system |
| installation period | 2-3 days (no need to lay pipelines) | 15-30 days |
| Space occupancy | Single cabinet occupying ≤ 0.8 ㎡ | Special gas cylinder room+pipeline well required |
| Maintenance cost | Annual maintenance costs reduced by 40% | High proportion of pipeline inspection costs |
| Applicable scenarios | Independent protection zone below 200 square meters | Large scale integrated complex centralized protection |
1. Flexible deployment and quick response
Adopting a pre pressurized storage bottle design, the storage pressure of the fire extinguishing agent is 4.2MPa, and the complete submerged fire extinguishing can be completed within 10 seconds
Single cabinet protection volume can reach 200m ³ (certified by FM), supporting multi cabinet networking to achieve greater space coverage
2. Clean fire extinguishing, zero secondary damage
Extinguishing fires through a dual mechanism of chemical inhibition (interrupting the combustion chain reaction) and physical cooling
After extinguishing the fire, there should be no residue to avoid damage to precision instruments/cultural relics (verified by the National Fire Electronic Quality Inspection Center)
3. Intelligent linkage, precise prevention and control
Standard IoT controller, supporting triple triggering modes of temperature sensing, smoke sensing, and manual emergency stop
Can be connected to BIM intelligent fire protection platform, real-time monitoring of pressure values (accuracy ± 0.15MPa)
4. Low carbon and environmentally friendly, long-lasting and reliable
ODP (Ozone Depletion Potential)=0, GWP value is reduced by 98% compared to traditional Halons
The steel cylinder has undergone 100000 fatigue tests and has a service life of 15 years (in accordance with TSG 23-2021 Pressure Vessel Specification)
5. Economical and practical, friendly to renovation
The renovation of old buildings does not require the destruction of the original structure, saving more than 30% of engineering costs
Support non-conductive fire extinguishing, and can be started in places with live equipment without power outage
