I hope are all doing well,

I am referencing Section 8.6.2.2 of the NFPA 13 (2022), which mentions that 
ESFR sprinklers can be used with premixed antifreeze solutions, provided they 
are listed. Based on this, would it be possible to protect a cold storage 
warehouse (refrigerated) using ESFR sprinklers along with the recommended 
tables if a listed sprinkler compatible with a premixed antifreeze solution is 
available? Has anyone implemented this solution before?. Due to certain 
constraints, using dry barrel sprinklers is not possible, and implementing dry 
pipe systems would require rack sprinklers, which are troublesome.

Additionally, I have been exploring the possibility of using heat tracing as an 
alternative, but so far, I have not found any viable options. Any insights or 
recommendations on this matter would be greatly appreciate

Best regards,
José
