Since we are referring to K-11.2 dry pendent sprinklers for a freezer, if the contents are high enough to be considered storage (thus the discussion on required K-factor to density), you might as well stop the discussion. 12.6.3 not only requires the larger k-factor but also that the sprinkler be listed for storage. The cut sheets I've looked at simply says freezer. AS any one found any dry types so listed?
