ESFR Fire Sprinkler

The available ESFR Fire Sprinkler of Fuxeon® is the full name for the early suppression rapid response sprinkler. It is a large-diameter sprinkler and an essential component of the automatic sprinkler fire suppression system. It can quickly and automatically open in the early stages of a fire and distribute a certain amount of water with the specified shape and density over the designed protected area. It is the only fire-suppressing sprinkler head that can suppress fires early on. Its response time index (RTI) is≤28±8(m.s) ^0.5, thus it has the advantages of rapid fire response and high water flow, and is used to protect high-stack and high-rack warehouses, as well as warehouses storing plastic products and mixed goods.

Technical Parameters

Product features

1.Traditional sprinkler systems are designed to contain a fire while awaiting the arrival of the fire department. However, the ESFR sprinkler is designed to activate quickly at the initial stage of a fire, releasing a massive amount of water to directly suppress or even extinguish it. It is specifically designed to protect warehouses with high stacks and racks, such as logistics centers and large supermarket warehouses. These locations experience high fire loads and rapid fire development, making traditional sprinkler systems difficult to effectively respond to.

2.The temperature-sensitive elements (glass bulbs or fusible alloys) of ESFR sprinkler heads have an extremely high thermal sensitivity, with a faster response speed than standard sprinkler. They can quickly detect temperature and activate during the early stages of a fire, before a large amount of heat has accumulated on the roof, intervening before the fire spreads.

3.The K factor of ESFR fire suppression system is large, mainly K14.0 (202), K16.8 (242), K25.2 (363). This means that under the same water pressure, it can spray out a huge amount of water far exceeding the nozzles in common sprinkler systems (usually K5.6 or K8.0), forming a powerful water column.

4.The water droplets discharged from the Brass ESFR fire sprinkler head are characterized by their large particle size and sufficient kinetic energy, enabling them to effectively penetrate the upward thermal currents of a fire and directly reach the surface of the burning material. In contrast, the small water droplets from traditional sprinkler heads are easily dispersed and evaporated by the rising hot air currents, failing to effectively reach the base of the fire source.

FAQ

Q1: What materials are used for ESFR fire sprinkler?

The sprinkler body is made of high‑strength forged brass with anti‑corrosion finishing. The heat-sensitive bulb, frame, deflector and internal components adopt high-temperature resistant alloy and high-precision sealing materials. The overall structure features high pressure resistance, impact resistance and long-term stability.

Q2: What core advantages does ESFR structure bring compared with standard sprinklers?

Different from ordinary sprinklers, ESFR adopts fast-response thermal element and large-flow design. It can activate at an early fire stage, discharge large water volume quickly, and directly suppress high-challenge storage fires. It reduces fire damage and simplifies warehouse fire protection system configuration.

Q3: Can ESFR fire sprinkler adapt to high bay and harsh indoor environments?

Yes. Premium brass housing delivers excellent rust and moisture resistance. The optimized deflector structure ensures stable water distribution even in high ceiling spaces. It can operate reliably in dusty, dry and long-term closed warehouse environments for 24/7 standby.
