The Viking Corp. has added a 25.2K ESFR pendent sprinkler to its current ESFR line. This roof-mounted K25.2 sprinkler meets FM guidelines for protecting buildings to 45 ft. in height that have storage up to 40 ft. high. It can protect most common storage materials, including severe-challenge fires of palletized and solid pile storage, from Class I commodities to rubber tires. With its higher K-factor, the K25.2 provides ESFR performance with lower end head pressures than 14K ESFR sprinklers. As a result, smaller pipe, fittings and hangers can be used, and system fire pumps can be downsized or eliminated.The Viking Corp.
