Product Information

"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.     K40.4 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: 13.1m with ceilings up to 14.6m and FM - 15.2m with ceilings up to 16.8m    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 1.83m  (UL - 13.1m storage) or 2.44m (FM - 15.24m storage)."
