PENDENT SPRINKLER K25.2 VK510
DESCRIPTION
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 specific heights.*
• Reduce or eliminate the need for a system fire pump.
• Provide flexibility when sizing system piping.
Viking VK510 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, multiple row, and
portable open rack storage (no open-top containers or solid shelves).
Viking ESFR Pendent VK510 Sprinklers provide protection of most
common storage materials, including:
• Encapsulated or unencapsulated Class I, II, III, and IV commodities*.
• cULus Listed for protection of cartoned unexpanded plastic
commodities and FM Approved for protection of cartoned and uncartoned
unexpanded plastic commodities*.
• FM Approved for protection of exposed expanded polystyrene and
exposed expanded polyurethane commodities*.
In addition, some storage arrangements of rolled paper, flammable liquids,
aerosols, and rubber tires may be protected by Viking ESFR Pendent
Sprinkler VK510.
