QMQ4.2/100N-DY Pipe network type heptafluoropropane fire extinguishing system is a high-efficiency gas fire extinguishing equipment designed to protect important places, especially suitable for comprehensive protection needs of large buildings or multiple protection areas. The system uses heptafluoropropane (HFC-227ea) as a fire extinguishing agent. With its environmental protection, safety and residue-free characteristics, it performs well in electrical equipment, precision instrument rooms and high-value data storage. Dingya's pipe network fire extinguishing system not only conforms to international fire protection, but also provides users with a complete, safe and efficient fire extinguishing solution.
QMQ4.2/150N：It is suitable for places with large protection area and 150KG fire extinguishing agent filling capacity.
QMQ4.2/100N：Applicable to medium-sized protective area, fire extinguishing agent filling capacity of 100KG place.
Both models adopt a pipe network design, and the fire extinguishing agent can be transmitted to multiple protection areas through the system pipe network, which greatly improves the coverage and fire extinguishing efficiency of the system.
· Environmental protection and pollution-free
Heptafluoropropane fire extinguishing agent is ozone-free (ODP = 0), and vaporizes quickly after extinguishing the fire, without residual solids or liquids, avoiding secondary pollution to or equipment. The fire extinguishing system is especially suitable for places with high cleanliness requirements, such as data centers, archives and laboratories.
· Efficient and fast fire extinguishing
Through endothermic and chemical inhibition, the system can quickly extinguish fires. The QMQ4.2 series pipe network fire extinguishing system is designed to complete the spraying of fire extinguishing agent within ≤ 8 seconds, ensuring that the fire source is controlled in the shortest possible time, thereby causing damage to property and equipment by fire.
· Wide applicability
The system is designed to be suitable for Class A (solid matter), Class B (liquid fuel), Class C (gas fuel) fires, and is widely used in various important protection areas, such as power stations, substations, precision instrument rooms, control centers and other places. At the same time, it can also provide simultaneous protection for multiple protection areas.
· Safe and reliable
The pipe network design ensures that the fire extinguishing agent is evenly distributed in each protection area, and the fire extinguishing agent is transported to the source of the fire through high-pressure pipelines. The system is equipped with an electromagnetic starting device, which automatically monitors and responds quickly when a fire occurs. In addition, the system is equipped with a safety pressure relief valve to avoid accidents caused by high pressure and ensure the safe operation of the system.
· Space Savings
The system stores the fire extinguishing agent in the special gas cylinder room, and does not occupy the space in the protection area. Different from the cabinet fire extinguishing system, the pipe network fire extinguishing system is especially suitable for building structures that require wide-area coverage, and solves the fire extinguishing needs of multiple protection areas.
