ESFR sprinkler in glicol installation
(OP)
Hi,
I have installation with 120 ESFR sprinklers. Can I use a glicol medium with ESFR sprinklers according to NFPA13?

The data sheet clearly shows that for an ESFR COLD STORAGE SYSTEM, it is limited to:
"Commodity Classification: Limited to Class II or less."
Just because it's ESFR does not mean you can protect everything by converting to anti-freeze. You are severely limited to only Class II Commodities.

As been stated here numerous times ESFR systems are not the panacea to solve anything storage related.

Viking's antifreeze system is still pretty pricey and makes for a big maintenance headache.
My guess is you are trying to stay away from in-racks so I would look strongly at the Tyco Quell system first.

If you have larger warehouse or need a fire pump regardless the quell system will be more cost effective.
Also, their are the maintenance costs if you eliminate the in-rack sprinklers since those never get hit by forklifts.
Contactors need to be licensed by Tyco to install the Quell system so not every sprinkler contractor is qualified.
