Early Suppression Fast Response (ESFR) Sprinklers

Viking’s Early Suppression Fast Response (ESFR) Sprinklers are high volume ceiling mounted sprinklers that exceed in the protection for severe challenging fires such as palletised and solid pile storage and single, double, and portable open rack storage (no open-top containers or solid shelves). A key advantage of an ESFR system over a Conventional sprinkler system is the possible elimination of the requirement for in-rack sprinklers in rack storage areas. ESFR systems are also specially designed to suppress the fire by discharging a large volume of water directly to the fire to reduce the heat release rate, while regular systems aim to simply control the fire.

Viking’s Model VK514 is now FM Approved as a Quick Response Storage Sprinkler providing ceiling-only sprinkler protection for storage facilities up to 16.7m in height. The K28 ESFR can help increase racking flexibility while also reducing the installation and maintenance costs associated with in-rack sprinklers. It has a Design Pressure of 5.5 bar. The K28 is available in ordinary and intermediate temperature ratings - 74° C and 96° C.
