Product Details
Product Formation
The 2.5-inch (approximately 63.5mm, nominal diameter DN65) fire water curtain sprinkler is a low-pressure, wide-coverage fire separation device. It achieves fire compartmentation, thermal radiation isolation, or equipment cooling by spraying a continuous water curtain. Its core features include a 65mm large-diameter water inlet design and a water curtain forming structure. Different from ordinary sprinklers (with point spraying) and water cannons (with jet spraying), it focuses on "planar protection" and is suitable for scenarios where it is necessary to block the spread of fire and isolate high-temperature areas. In the product name, "2.5"" corresponds to "65mm" (2.5 inches ≈ 63.5mm, which is often simplified to 65mm in engineering). "Water Shield Curtain" emphasizes its dual protection functions of "water shield + water curtain".
The 2.5-inch/65mm fire water curtain nozzle is a key component of "active fire compartmentation" in fire protection systems. Through its large-diameter water inlet and precise water curtain structure, it forms a uniform protective barrier under low pressure, combining high efficiency, cost-effectiveness, and adaptability to various scenarios. It is widely used in fire risk prevention and control across buildings, industrial facilities, transportation, and other fields.

Product Features
The 2.5-inch/65mm fire water curtain nozzle, with its core positioning of "area protection, low consumption and high efficiency, precise isolation," is specifically designed for fire compartmentation, thermal radiation isolation, and equipment cooling in fire protection systems. Its features include:
Continuous water curtain form: Different from ordinary sprinklers (point-like water droplets) and water cannons (columnar jets), through slit-type/orifice plate-type/combined water curtain structures (narrow and long openings or dense small holes), the water flow is converted into a uniform and continuous sheet-like water curtain (thickness ≥ 0.5mm), forming a physical isolation barrier.
•Dual protection functions:
•Fire and smoke blocking: The water curtain can directly block the spread of flames and high-temperature smoke (for example, replacing solid firewalls in shopping mall atriums to separate fire while maintaining space transparency);
•Cold isolation and cooling: Continuously cool the surfaces of equipment or combustibles in adjacent areas (for example, isolation between reactors in petrochemical plant areas to reduce the risk of secondary fires caused by thermal radiation).
Rectifier design: Equipped with internal spiral blades or flow guide grooves to convert turbulent flow in the pipeline network into uniform water flow, preventing curtain breakage or localized over-density.
Optional water curtain forms: Slot type (continuous water curtain,), orifice plate type (water droplets superimposed to form a curtain, offering softer coverage), combined type (slot + orifice plate composite, enhancing resilience), adaptable to different separation needs.
