FM Approved K25 Upright Sprinkler (VK598)

  • FM Approved for use in dry or preaction systems to protect Class I-III commodities with storage heights of up to 40 ft (12,2 m) in warehouses as high as 45 ft (13,7 m), without the need for additional in-rack sprinkler protection.
  • By eliminating in-rack sprinklers, the VK598 sprinkler can significantly reduce overall system costs in freezers and refrigerated warehouses, while also increasing racking flexibility and lowering the potential risk of damage to the system by warehouse operators.
  • With its higher K-factor, Viking's new K25 upright sprinkler provides for a lower overall starting pressure when compared to other protection options.
  • When used in dry or pre-action systems, the VK598 design criteria requires specific water delivery times, as indicated on the product's technical data sheet. Viking's Technical Services team will assist customers with performing the required fluid delivery calculations.
  • Approved for use with open frame rack, solid piled, palletized, and bin box storage configurations.
  • Maximum sprinkler spacing of 10 x 10 ft (3 x 3 m).
  • Also approved for use in wet pipe systems and non-storage applications.
  • Available in 155°F, 175°F, 200°F, and 286°F temperature ratings.
