High Pressure Fine Water Mist Fire Extinguishing Device

Mingxing high-pressure fine water mist fire extinguishing device uses a working pressure of more than 10MPa to convert water into fine water mist for extinguishing fire. It is suitable for Class A solid, Class B liquid, Class C gas, Class K cooking and Class E electrical fires. The system provides various types such as open, closed and closed pre-acting, which can effectively extinguish a variety of fire forms including blocking fire. The device uses water as the fire extinguishing medium, uses little water, and has the functions of efficient fire extinguishing and rapid smoke suppression, which helps reduce secondary damage. The main pump adopts a maintenance-free design, the system has corrosion resistance and low maintenance costs. The device is produced in Yancheng, Jiangsu, and belongs to the XSWBG series and supports distribution in many places across the country.

Product Description

The High Pressure Fine Water Mist Fire Extinguishing Device is engineered to meet internationally recognized fire protection guidelines and is configurable to comply with project-specific requirements. Components are fabricated from corrosion-resistant stainless steel and machined brass where required; sealing materials are selected for hydrostatic and thermal stability. The system is suitable for areas where water mist fire suppression for engine rooms, data center water mist suppression, or machinery space localized suppression are required. Certification options include third-party testing protocols such as UL/ FM listings and relevant EN standards depending on the chosen certification path. Design documentation includes hydraulic calculations, nozzle spacing tables, and maintenance procedures to support performance verification and integration into asset management workflows.

Application Areas

This device is suitable for the following scenarios where fast, low-water-volume suppression is required:

Data center localized fire protection and server room suppression.
Marine engine rooms and machinery spaces requiring water mist fire suppression for engine rooms.
Archive and library protection where water-sensitive assets need limited water exposure.
Industrial process enclosures and transformer vaults with constrained ventilation.
Commercial kitchens and restaurant equipment hoods when combined with applicable grease-fire mitigation measures.

FAQ

1. How is the high-pressure fine water mist system integrated with existing fire detection and building control systems?

Integration is achieved through standard interface points: dry contact inputs/outputs for supervisory and trip signals and a communication bus (for example, MODBUS RTU) for advanced telemetry. The system supports interlock logic so that detection signals (smoke, heat, or flame detectors) can initiate pump start, nozzle release or valve actuation. For projects requiring BMS integration, provide the system I/O map and network protocol during design review to ensure proper addressing and alarm routing. All control wiring must follow local electrical codes and the system should be commissioned with functional tests to validate sequence-of-operations.

2. What are the expected maintenance intervals and how does the system address long-term reliability concerns like pipework corrosion?

Routine inspection intervals typically follow national and manufacturer recommendations: monthly visual checks of indicators and valves, quarterly functional tests of control circuits, and annual hydraulic tests including pressure checks of pump and piping. To mitigate corrosion, wetted components are specified in 316L stainless steel or brass, and internal surfaces are passivated where applicable; materials selection should align with site water quality and treatment (e.g., hardness, chloride content). A documented inspection and replacement schedule for seals and non-metallic parts reduces the risk of degraded performance over time.

3. Can the water mist system be used as a retrofit solution for existing sprinkler installations?

In many cases, a high-pressure fine water mist system can be implemented as a retrofit for specific hazard zones, but compatibility depends on available space, hydraulic infrastructure and approval from local authorities having jurisdiction. Retrofit design requires assessment of pump room capacity, pipe routing for high-pressure piping, and potential reinforcement of structural supports for the skid. Provide existing as-built drawings and sprinkler hydraulic calculations to allow the engineering team to perform a feasibility study and propose a revised layout that meets relevant codes and installation requirements for high-pressure water mist systems.
