Product Description
Pendent Type Sprinkler is a small and compact hydraulic fitting which is designed for the convert the thick stream of water coming from the main supply source into fine sprinkled form for better dispersion over large areas. It is made up by using stainless steel which gives higher tensile strength and make it capable to withstand high pressures. This component part is provided with a threaded rod to make tight and leakproof connections with the flow channels having same threaded configuration.

Efficient Fire ProtectionThis pendent sprinkler is engineered to provide rapid response in fire emergencies. Its automatic activation relies on a heat-sensitive glass bulb, available in multiple colors to indicate working temperatures from 57C to 93C. The sprinklers downward vertical placement ensures wide circular coverage, maximizing safety in buildings.
Quality Materials and FinishBuilt with a corrosion-resistant brass body and glass bulb, this sprinkler offers durability for both commercial and residential applications. The devices chrome-plated or polished exterior enhances longevity and visual appeal, while requiring only basic, low-frequency maintenance for sustained performance.
Consistent Water DistributionWith a discharge coefficient of 80 and a max flow rate of up to 115 L/min, this sprinkler guarantees uniform water coverage over areas between 912 m. The design ensures effective extinguishing of Class A and B fires, promoting safety and property protection in high-risk environments.
FAQs of Pendent Type Sprinkler:
Q: How does the pendent sprinkler activate during a fire?
A: The sprinkler uses a heat-sensitive glass bulb, which bursts when exposed to a predetermined temperature (indicated by the bulb color). This releases water automatically from the ceiling-mounted unit to suppress the fire.
Q: What do the different bulb colors indicate?
A: The bulb colorsred, yellow, green, and bluecorrespond to specific activation temperatures: red (57C), yellow (68C), green (79C), and blue (93C). This helps select the right sprinkler based on the environments fire risk profile.
Q: Where is this sprinkler typically installed?
A: This pendent type sprinkler is mounted on ceilings in commercial and residential buildings, providing widespread coverage in rooms, hallways, or common areas to maximize fire safety.
Q: What is the benefit of its circular spray pattern?
A: The circular spray pattern ensures that water is distributed uniformly over a coverage area of 912 m, offering consistent extinguishing performance across the protected space.
Q: What kind of fires can the sprinkler combat?
A: It is designed to suppress Class A and B fires, making it suitable for environments with risks from combustible materials and flammable liquids.
Q: How often does the sprinkler require maintenance?
A: This sprinkler is noted for low maintenance requirements. Regular inspections are recommended to ensure reliability, but the high-quality materials and finish minimize the need for frequent servicing.
Q: Is the sprinkler suitable for high-pressure environments?
A: Yes, it operates reliably within a standard working pressure range of 1.21.5 MPa and requires a minimum operating pressure of 0.35 MPa.
