VK510 - ESFR Pendent Sprinkler (K25)

Viking Early Suppression Fast Response (ESFR) Pendent Sprinkler VK510 incorporates the capability to suppress specific high-challenge fires. The addition of a larger K-Factor allows ESFR performance at lower end-head pressures than ESFR K14 sprinklers. K25.2 ESFR sprinklers can:

• Eliminate the use of in-rack sprinklers when protecting high-piled storage of certain specified materials up to 40 ft. (12.2 m) with ceilings up to 45 ft. (13,7 m).
• Reduce or eliminate the need for a system fire pump.
• Provide flexibility when sizing system piping.
