Abstract: A dry sprinkler has a casing tube having an inlet orifice and an outlet orifice. When the sprinkler is in a non-actuated state, an inlet seal assembly operatively seals the inlet orifice and an outlet seat assembly operatively seals the outlet orifice. A translating member extends through the casing tube between an inlet and an outlet. The translating member axially translates from a first position, in which the translating member retains the inlet seal assembly in a sealed state, to a second position, in which the translating member releases the inlet seal assembly, toward the outlet when the outlet seat assembly is released. The sprinkler has a nominal K-factor greater than 17 gpm/(psi)1/2. In addition, a difference between a cross-sectional area of the casing tube and a cross-sectional area bounded by an outer perimeter of the translating member is more than 30% of the cross-sectional area of the casing tube.
