Product Overview
Close Type Pendent Water Curtain Nozzle
Traditional fire sprinklers often feel like an eyesore in carefully curated spaces-sticking out, breaking the clean lines of modern interiors, and clashing with luxury hotel lobbies, minimalist office ceilings, or high-end residential finishes.
Our Flush Pendent Sprinkler redefines this compromise. It sits nearly flush with the ceiling, concealed behind a customizable cover plate, so it blends seamlessly into any design aesthetic. No more unsightly protrusions, no more disrupting your vision. When everything is calm, it's just a subtle part of your ceiling; when danger strikes, it transforms into a life-saving guardian, ready to act instantly.
This is fire protection that doesn't shout its presence-it works quietly, reliably, and beautifully, without ruining your interior design.
Core Innovation: Closed Sealing Structure, Zero Leakage Design
2.1 Permanent Water Tightness Without Decoration Damage
Traditional open water curtain nozzles have no internal sealing structure, resulting in frequent dripping and water seepage when the pipeline is filled with water long-term. This easily damages ceiling decoration, electrical pipelines and interior finishes, causing high rework and maintenance costs. Our product adopts an optimized closed sealing system with a precision 3mm glass bulb as the core sealing component. The nozzle remains completely sealed under normal conditions, achieving zero leakage even with long-term pipeline water storage. It allows advance pipeline layout for fine decoration projects without secondary waterproof treatment, greatly shortening the construction cycle and reducing project risks.
2.2 Pure Mechanical Activation, No Electric Control Required
This water curtain nozzle relies on physical temperature induction instead of electronic linkage. When the ambient temperature reaches the rated action temperature, the glass bulb bursts instantly to unlock the sealing structure and start water spraying immediately. It requires no solenoid valve, fire alarm host or extra electrical wiring, which greatly simplifies the entire fire water curtain system structure and reduces overall project cost. Without electronic components, the nozzle avoids aging and circuit failure risks, maintaining stable performance in humid, dusty, underground pipe gallery and other harsh environments with extremely low maintenance difficulty.
Optimized Water Distribution Structure, Full Coverage Water Barrier
3.1 170° Wide-Angle Uniform Water Spraying
We optimize the internal diversion tank and water outlet structure to achieve a 170° ultra-wide spraying angle. The water flow spreads horizontally and evenly to form an integrated and continuous water curtain without dead zones, broken flow or thin water layers. Reasonable linear arrangement of multiple nozzles can form a seamless water barrier, which effectively resists flame penetration, isolates high-temperature heat radiation and prevents cross-regional smoke diffusion, greatly improving building fire safety performance.
3.2 Standard K5.6 (K80) Flow Coefficient
Equipped with a standard K=5.6 (K80) flow coefficient, the nozzle delivers stable and controllable water output. It fully complies with international fire protection pipeline design standards, matching conventional hydraulic calculation and pipeline pressure configuration perfectly. The water flows out in a gentle and layered manner without high-speed splashing, avoiding water waste and ensuring maximum protection efficiency under standard water pressure.
Global Universal Design, Multi-Scenario Compatibility
4.1 Dual Thread Options for Global Installation
To adapt to different national pipeline standards, our nozzle supports two mainstream thread specifications: 1/2" NPT American standard thread and R1/2" British taper thread. NPT threads are suitable for North American markets, while R1/2 threads apply to Europe, Southeast Asia, the Middle East and other regions. One single product model covers most global installation requirements, reducing inventory pressure and simplifying procurement and stocking for international traders and engineering contractors.
4.2 High-Corrosion-Resistant Material Configuration
We provide two optional body materials to meet diverse working conditions:
Brass body with chrome plating: High machining precision, excellent sealing performance and cost-effective, ideal for conventional indoor scenarios such as shopping malls, office buildings and hotels.
Stainless steel body with chrome plating: Super acid and alkali resistance, anti-rust and salt-spray resistance, perfect for coastal buildings, chemical plants, cold storage and other harsh environments.
Both versions adopt polished chrome surface treatment to prevent scale accumulation, oxidation and corrosion, ensuring long-term stable water outlet and extending service life.
4.3 Universal 3mm Glass Bulb with Replaceable Design
The nozzle is equipped with a mainstream 3mm diameter temperature-sensing glass bulb, with multiple temperature grades including 57℃, 68℃, 79℃ for optional selection to adapt to different environmental temperature requirements. After fire activation, only the glass bulb and sealing kit need to be replaced instead of the whole nozzle, significantly reducing long-term operation and maintenance costs for engineering projects.
Pendent Installation Design, Easy Construction & Maintenance
Adopting a classic pendent downward installation method, the nozzle is suitable for ceiling suspension and concealed ceiling embedding. It does not damage the overall architectural decoration aesthetics. With a compact and miniaturized body, it can be installed in narrow spaces such as escalator sides, curtain wall gaps and roller shutter tops. The simple and fast installation process effectively saves construction time, while the exposed structure facilitates daily inspection and later maintenance.
