– K-factor 25.2 provides the required amount of water at lower pressure to protect higher ceilings and storage heights while eliminating the need for overhead sprinklers. The VK598 is also approved for use with open frame racks, stacked, stacked and bin-box storage configurations, with a maximum sprinkler distance of 10 x 10 ft (3 x 3 m).
