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.

Dry Pendent ELO Sprinklers

Viking’s Standard Response and Quick Response Dry Pendent ELO Sprinklers are the first of their kind as the only FM Approved ELO dry barrel models. With a nominal K-factor of 11.2 (161), the new sprinklers can reduce the overall water demand required in many cold storage sprinkler systems, particularly where ceiling heights are 35 ft. (10,5 m) and below. By reducing water supply requirements, Viking’s new dry ELO sprinklers can help lower system costs by possibly eliminating the need for a fire pump and reducing the size of system piping and related components. Plain barrel, standard adjustable, and recessed adjustable models are all available in both standard and quick response options.

• The only FM Approved ELO dry barrel pendent sprinkler.
• Ideal for a wide variety of low temperature commercial and cold storage applications subject to temperatures below 40° F.
• 1 ¼” barrel and thread size – requires 1 ¼” tee.
• Lengths in 6” increments from 12” to 48” (305 to 1,219 mm) for plain barrel, standard adjustable, and recessed adjustable models.
• Available in ordinary, intermediate, and high temperature ratings; 165° F (74° C), 205° F (96° C), and 280° F (138° C).
