NFPA 13 2025 edition has 23.4 for Exposed Expanded Grp A plastics. But I don't know if you will be compatible with a refrigerated space. Tyco makes a K25 dry pendent ESFR.
It may not be the pipe sizes you want to see. I don't know if dry pendents are an option in your facility. Travis Mack, SET M.E.P.CAD | Instructor / Support 181 N.

The new client will be storing fish in exposed expanded Group A plastic coolers, and these will be stored on single, double and multi row racks. The existing sprinkler system is designed to 0.30usgpm over 2000 ft² plus two levels of in-rack sprinklers. I cannot find any protection schemes for design area applications that will provide protection schemes for the exposed expanded Group A plastics. Is there something I am missing or can someone point me in the right direction. Thank You James Crawford Phaser Fire Protection Ltd.
