TYCO Model ESFR-1 Pendent Sprin-klers are Early Suppression, Fast Response (ESFR) sprinklers having a nominal K-factor of 14.0. They are suppression-mode sprinklers that are especially advantageous as a means of eliminating the use of in-rack sprinklers when protecting high-piled storage. Model ESFR-1 Sprinklers are primarily, now with industry leading highest ceiling-only protection. (48 feet) for the narrowest aisles (5 feet), 25.2 K-factor. Features: Early Suppression, Fast Response (ESFR) Suppression-mode sprinklers that are especially advantageous as a means of eliminating the use of.
6/14/2016 · The K-factor values of ESFR sprinklers have changed over the years, too. Since the introduction of the original K14.0 (K200) ESFR sprinkler, other ESFR sprinklers have included K16.8 (K240), K22.4 (K320), K25.2 (K360); and one company recently introduced a K28.0 (K400) sprinkler.
Residential sprinklers often have k-factors less than 5.6. ESFR and CMSA require minimum K11.2 (NFPA 13-2016 6.2.3.5). ESFR are tied directly to the hazard it protects. Back to refining the hydraulics in a system – increasing the k-factor of a sprinkler allows more.
Viking Early Suppression Fast Response (ESFR) Pendent Sprinkler VK500 is a fast response fusible element type sprinkler designed for early fire suppression. With a 14.0 (202 metric) nominal K-Factor and special deflector, this sprinkler produces large, high-momentum water droplets in a hemispheric pattern below the deflector.
Compare Flow of K-Factors with New Calculator, Compare Flow of K-Factors with New Calculator, K-factor (fire protection) – Wikipedia, K-factor (fire protection) – Wikipedia, In fire protection engineering, the K-factor formula is used to calculate the discharge rate from a nozzle. Spray Nozzles can be fire sprinklers or water mist nozzles, hose reel nozzles, water monitors and deluge fire system nozzles. K-Factors calculated in Metric units; The flow rate of a nozzle is given by. q = K p.
