Product Details
74 Degree ESFR Fire Sprinkler
ESFR (Early Suppression, Fast Response) fire sprinkler systems are advanced sprinkler systems designed to provide rapid and effective fire suppression in high-hazard environments such as warehouses, distribution centers, and other large storage spaces.
ESFR sprinklers are specifically engineered to provide early suppression of fires by releasing a large volume of water in a short period of time. They typically have larger orifices and higher water flow rates compared to standard sprinklers. The distinguishing feature of ESFR sprinklers is their ability to discharge water directly towards the fire, creating a strong, concentrated spray pattern that can effectively penetrate the fire plume and suppress the flames.
ESFR sprinklers are typically ceiling-mounted and are designed to be installed at specific maximum distances from storage racks or other obstructions. They operate at higher pressure levels, usually between 50 psi (pounds per square inch) and 175 psi, allowing for greater water delivery and coverage.
Advantages:
1.Cold and frost resistant due to the fusible alloy.
2.High pressure resistant and durable.
3.Quick response and higher fire extinguisher effect. K=16.8
Specifications
(1 ) Nominal caliber: 20mm, connection thread: R3 / 4 "or NPT3 / 4", water supply branch ≥ DN50.
( 2 ) Flow characteristic coefficient : K = 242 or K=14.2.
(3 ) Response time index (RTI) is 28 ±8m ·s ~ (-1) ~ (0.5).
(4 ) Maximum working pressure: 1.2 MPA.
(5 ) 100% Ex-factory pressure test: 3.45MPA
