New K25 Extended Coverage Sprinkler for Storage Applications

Friday, June 10, 2011

Hastings, MI, USA – Viking Corporation, a global leader in fire protection and life safety systems, is pleased to announce the availability of its new model VK595 upright fire sprinkler. The VK595, which has a 25.2 (363) K Factor, is cULus Listed as a density/area storage sprinkler with a maximum coverage area of 14 x 14 ft (4.3 x 4.3 m). The new upright-style sprinkler is also FM Approved as a quick response, extended coverage sprinkler for both storage and non-storage applications.

The VK595 is well-suited for extra hazard, high-pile storage, rack storage, and “big box” retail applications. As an extended coverage sprinkler, the VK595 can reduce installation costs by decreasing the overall number of sprinklers required in a system. Additionally, the larger K Factor can provide the flows needed for higher-density requirements at significantly lower operating pressures. The VK595 also allows for greater installation flexibility relative to obstructions, when compared to ESFR storage sprinklers. The sprinkler is cULus Listed for use within trusses or bar joist having non-combustible web members greater than 1 inch (25 mm), provided that standard “four times” obstruction rules are followed.

The VK595 is available in 165°F (74°C) and 214°F (101°C) temperature ratings. Concurrent with the introduction of this new sprinkler, Viking has also released a new installation wrench, part number 16888F, specifically used for proper installation of the VK595 sprinkler. The VK595 is the latest addition to Viking’s leading product line for storage fire protection.
