Fast Response: Equipped with a 74°C fusible alloy temperature-sensitive element, it has a Response Time Index (RTI) ≤ 28 (m·s)^0.5, activating within seconds at the initial stage of a fire.
High-Flow Extinguishing: With a discharge coefficient K=363, it delivers large-diameter, high-energy water droplets that can penetrate flames to cool burning materials, suppressing fire spread at its source.
Application Scenarios & Advantages
High-Bay Protection: A single sprinkler covers up to 9.3㎡, protecting warehouses with roof heights up to 13.5m and pile heights up to 12m—no additional in-rack sprinklers are required.
Scenario Compatibility: Suitable for high-pile storage of goods like cartons, plastics, and rubber tires, covering Class I-IV commodity warehouses. It is a "standard protection solution" for logistics and e-commerce storage facilities.
Key Specifications
Connection: DN25 (1-inch) thread, compatible with mainstream fire protection pipelines.
Operating Pressure: 0.14-0.34MPa, maximum pressure resistance of 12bar.
Material: Full brass body, corrosion-resistant, suitable for low-temperature/normal-temperature storage environments.
Certifications: Complies with GB5135.9 standards, certified by UL/FM/3C fire safety certifications.
Its core value lies in replacing traditional multi-sprinkler setups with "single-sprinkler wide coverage + high-flow water discharge", significantly reducing the installation and maintenance costs of high-bay fire protection systems while achieving more efficient early fire suppression." />
