Sprinkler Heads (Automatic)

-- Steady & Reliable Manufacturer --

Introduction: Precision, Automatic Fire Suppression

Automatic sprinkler heads are the fundamental component of modern fixed fire suppression systems, designed to detect fire-induced heat and automatically discharge water directly onto the source of the fire. As a critical, life-saving component, the precision engineering and reliability of each sprinkler head are non-negotiable. We manufacture and supply a wide range of types, including pendant, upright, sidewall, and concealed sprinklers, covering various temperature ratings and installation requirements.

All our sprinkler heads are produced under strict quality control and are available with mandatory third-party certifications (UL Listed, FM Approved), ensuring their performance meets global fire safety codes (NFPA 13). Key technology centers on the thermal operating element—either a fusible link or a glass bulb—which is precisely calibrated to rupture at a specific temperature. The heads are constructed from high-quality brass or chrome-plated materials to ensure long-term corrosion resistance and integrity.

We offer standard, quick-response, and specialized types (e.g., residential, ESFR for high-rack storage), ensuring we provide the correct hydraulic solution for every building category, from high-rise offices to industrial warehouses. Our commitment is to deliver a reliable, instantly-active suppression element that minimizes fire spread and water damage. (Approx. 570 words)

Advantage: Certification, Response Speed, and Reliability

  • UL and FM Certification: All core product lines carry the required third-party listings, ensuring reliability and acceptance in high-value international projects.
  • Quick Response Technology: Offering fast-response bulb models (typically 3mm bulbs) that activate rapidly, drastically reducing the fire growth phase compared to standard response.
  • Precise K-Factor Control: Hydraulic performance (K-Factor) is precisely calibrated, ensuring accurate water flow delivery matching the specific hydraulic calculations of the fire system designer.
  • Corrosion Resistance: Standard brass construction with optional specialized coatings (e.g., Teflon, Wax) for use in highly corrosive or moist environments.
  • Aesthetic Options: Concealed and recessed models with matching cover plates are available to integrate seamlessly into modern architectural designs.
  • Wide Temperature Range: Availability of standard, intermediate, and high-temperature ratings for use in boiler rooms, skylights, or extreme climate zones.

FAQ

The K-Factor defines the flow rate of water through the sprinkler head at a given pressure, calculated using the formula Q=KP​. It is essential for hydraulic calculations to ensure adequate water delivery.

Pendant heads hang down from the pipe and spray water downwards, ideal for finished ceilings. Upright heads point upwards and spray water against a deflector plate, used mainly in exposed piping systems (e.g., attics, machinery rooms).

Standard industry codes (NFPA) require dry sprinklers to be tested/replaced every 10 years, and standard quick-response sprinklers every 20 years, as the thermal element can degrade over time.

ESFR (Early Suppression Fast Response) sprinklers are high-volume, high-density heads designed for high-rack storage warehouses. They suppress the fire instantly rather than just controlling it, protecting goods from the top down.

The color of the liquid in the glass bulb indicates the specific temperature rating. For example, Red typically means 68∘C, Yellow means 79∘C, and Green means 93∘C.

Quick-response heads activate much faster, often before the fire grows beyond the incipient stage, which is vital for occupant escape time in a residential setting.

No. Sprinkler heads are part of a highly engineered, high-pressure fire suppression system. Installation, commissioning, and maintenance must be performed only by certified fire protection technicians.

Yes, we offer specialized coatings such as Teflon (TFE) or wax coatings to protect the brass body and heat element from corrosion in environments like chemical storage or cold storage facilities.

The most common thread size for standard commercial sprinkler heads is 1/2" NPT (DN15), though high-flow heads use 3/4" NPT (DN20).

Concealed heads are specialized products. The MOQ typically starts around 500 units due to the custom nature of the faceplates and the specialized assembly process.
