Upright Sprinkler

The FUXEON® upright sprinkler head is a glass bulb closed-loop fire extinguishing sprinkler head, suitable for open spaces without suspended ceilings, complementing ceiling-mounted pendant sprinkler heads. The vertical installation, relying on a scientifically designed parabolic water distribution structure, ensures uniform water distribution and high fire extinguishing efficiency, effectively solving fire protection challenges in large-span, open-plan factories and warehouses without suspended ceilings, and complies with domestic and international fire protection installation standards.

Working Principle

The core sensing component of the sprinkler head is a high-precision glass bulb filled with a solution with a high coefficient of thermal expansion. At room temperature, the glass bulb supports the internal sealing components, ensuring the overall sealing and pressure resistance of the sprinkler head and preventing daily leaks and malfunctions.

In the event of a fire, the ambient temperature rises rapidly. The solution inside the glass bulb expands due to heat, and the bulb bursts instantly upon reaching its rated temperature. The sealing limit is released, and the water pressure in the pipeline forces open the sealing components. The high-pressure water jet impacts the splash plate and spreads into a uniform parabolic water curtain, rapidly cooling the water and isolating it from oxygen, achieving efficient fire extinguishing and suppressing the spread of fire.

Technical Parameters and Product Models

FUXEON® upright sprinkler heads are available in two main series: DN15 diameter K80 and DN20 diameter K115. These include standard response and fast response types, covering multiple rated temperatures to adapt to various operating conditions. The K value is the flow coefficient, which directly determines the sprinkler head's water output and fire extinguishing coverage area.

Specifications: The K80 model has a rated flow rate of 80 liters/minute (1.33 liters/second) under rated pressure, suitable for small to medium-sized fire-fighting spaces; the K115 model has a maximum flow rate of 115 liters/minute (1.92 liters/second), offering large water output and wide coverage, suitable for high-risk fire-fighting scenarios such as large factories and warehouses.

Core Product Advantages

1. All-Brass Construction, Robust and Durable, High Safety

All FUXEON® upright fire sprinkler heads are manufactured using pure brass. Many manufacturers in the industry reduce brass usage or replace it with zinc alloy to control costs, resulting in products that are prone to breakage, corrosion, and high failure rates. This product adopts a one-piece all-brass structure, offering high structural strength, pressure resistance, and corrosion resistance, making it suitable for harsh industrial environments such as high temperatures and humidity. It eliminates potential equipment failures from the material source, ensuring stable and reliable quality.

2. Imported German JOB Glass Bulbs: Precise Sensing and Rapid Response

The temperature-sensing glass bulb is a core component of the sprinkler head. All FUXEON® products are equipped with high-precision temperature-sensing glass bulbs from the renowned German brand JOB, offering precise temperature sensing, rapid thermal response, and strong pressure stability. It activates instantly upon reaching the rated temperature, without false triggering or delay. Compared to inferior glass bulbs on the market, this effectively avoids sensor malfunctions and pressure breakage, ensuring accurate activation during sudden fires.

3. Wide Range of Specifications and Adaptability

The product range covers two flow coefficients and five rated temperature settings, offering both standard and rapid response modes. It is suitable for various operating conditions, including low-temperature indoor environments, high-temperature workshops, and special industrial sites. Standardized interfaces are compatible with mainstream fire-fighting water supply pipes, offering strong versatility and flexible adaptation to meet the diverse fire protection configuration needs of various projects.

Applicable Installation Scenarios

upright sprinkler heads must be installed in open spaces without suspended ceilings (basements, factories, warehouses, garages, factory roofs). When the clear height of the open space above the suspended ceiling exceeds 800mm and flammable materials are present, additional upright sprinkler heads must be installed in the open space for secondary protection. If the interior ceiling decoration plan is not yet finalized, a T-junction interface must be reserved in advance and sealed with a plug for easy future modification.

How to install an upright sprinkler?

1. The vertical installation distance between the sprinkler head and the ceiling must be strictly controlled between 75mm and 150mm to ensure optimal water distribution and temperature sensing effects.

2. When the height of the sprinkler water supply branch pipe exceeds 1000mm, a horizontal reinforcement bracket must be installed to fix the pipe and prevent displacement and shaking.

3. All installation work must comply with national fire protection construction specifications and be fine-tuned according to the actual site conditions.

The installation distance of the upright fire sprinkler head from the ceiling should be 75mm-150mm.

Real-world Engineering Application Cases

Case 1: Suzhou Residential Community Underground Garage Fire Protection Project

A large residential community in Suzhou has an underground garage without a suspended ceiling, posing fire hazards such as spontaneous combustion of electric vehicles. The project adopted FUXEON® T-ZSTZ 115-68℃ standard response upright sprinkler heads in batches, with a spacing of 3.6 meters in regular areas and 2 meters in high-risk areas. After the project was put into use, a lithium battery spontaneously combusted in an electric tricycle in the garage. The sprinkler heads quickly activated within 10 seconds, forming a full-coverage water curtain, rapidly extinguishing the initial fire, effectively preventing the fire from spreading and causing significant property damage, and ensuring the public safety of the community.

Case 2: Renovation Project of Open-Plan Office Area for a Technology Company in Zhejiang Province

A technology company in Zhejiang Province had an open-plan office area with a cement roof and no suspended ceiling decoration. The area had dense electrical equipment and posed a fire hazard. The project selected FUXEON® K-ZSTZ 80-68℃ fast-response upright sprinkler heads, evenly distributed along the beam and column structure. The product is highly sensitive to temperature, can quickly respond to initial high-temperature fires, and the system operates stably, successfully passing fire safety inspections multiple times, filling the gap in fire protection for open spaces without suspended ceilings.

FAQ

Q1: Can samples be provided for testing and acceptance?

A: Yes. We offer free samples for customers to use for performance testing, project inspection, and engineering verification. Simply contact our sales team to submit your requirements, and we will quickly arrange express delivery to help customers complete product verification and solution confirmation.

Q2: Do you support OEM/ODM services?

A: Yes. As a one-stop manufacturer and supplier of fire protection products, we provide full-process OEM and ODM customization services, supporting customers' personalized needs such as brand logo printing, parameter customization, and packaging customization, adapting to the differentiated cooperation needs of global distributors and engineering clients.

Q3: What is the difference between fast response and standard response sprinkler heads, and how should I choose?

A: The core difference between the two is the RTI response index and the start-up speed. The K80 fast response series (RTI≤50) has a faster sensing speed and is suitable for densely populated public places such as garages and office areas; the K115 standard response series (RTI 50~80) has stable performance and a larger water output, suitable for large spaces and high fire risk scenarios such as factories and warehouses. We can provide professional selection advice based on specific application scenarios.
