VK514 - ESFR Pendent Sprinkler (K28)
Viking Specific Application Early Suppression Fast Response (ESFR) Pendent Sprinkler VK514 incorporates the capability to suppress specific high-challenge fires. The addition of a larger K-Factor allows protection of higher hazard commodities at greater ceiling heights with lower end-head pressures.
K28.0 sprinklers can provide flexibility of fire protection designs and eliminate the use of in-rack sprinklers when protecting high piled storage of certain specified materials up to: UL - 43 ft. (13.1 m) with ceilings up to 48 ft. (14.6 m) and FM - 50 ft. (15.2 m) with ceilings up to 55 ft. (16.8 m)
Viking VK514 ESFR Pendent Sprinklers are primarily intended to protect the following types of storage, which tend to produce severe-challenge fires: palletized and solid pile storage and single, double, and portable open rack storage (no open-top containers or solid shelves). The VK514 is listed to utilize a minimum aisle width of 6’-0” (UL - 43’ storage) or 8’-0” (FM - 50’. storage).
