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.
Successfully meets new UL 1767 test standard and compliance program for ESFR sprinklers installed in rack storage with high clearances to ceiling (20 ft or greater)
Note: Some sprinkler head may or may not have Teflon tape applied. The heads have never been installed.
