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 value is relatively high, mainly including K14.0 (202), K16.8 (242), and K25.2 (363). This means that under the same water pressure, it can spray out a much larger volume of water than the ordinary ones (usually K5.6 or K8.0), forming a powerful water column.

4.Water droplets have the characteristics of large particle size and sufficient kinetic energy, which can effectively penetrate the upward-moving hot air flow from the fire source and directly reach the surface of the combustible material. In contrast, the water droplets sprayed by traditional nozzles are smaller and are prone to being blown apart and evaporated by the rising hot air flow, thus unable to effectively reach the bottom of the fire source.

FAQ

Q1: Which materials are used in the manufacturing process?

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 are the key advantages compared to the standard spray system?

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 it adapt to high-rise buildings 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.
