Why ESFR? What about a regular density/area using K11.2 dry pendents?
The other thing you have to consider is the cost of hanging the system, the cost of detectors and wiring, the additional pipe sizing due to the 30% increase in remote area and the additional maintenance required for a DIPA system. Factoring that in might make the cost of the K11.2 or ESFR dry pendents a little more palatable. I did a freezer recently where we ran the wet pipe outside and used K11.2 dry sprinklers. Worked out very well.

That sounds taken care of.

And Ron is correct. And the refrigerant type or N2 air dryer. And a game on detail project design and management. It is amazing that the number of all possible errors and errors you see in built systems that cause false trips approaches unity. Vic-type ftgs? Does designer specify cold temp gasket? Does purchasing agent order same gasket? Does fitter grab one from last
40f job out of coverall pockets? The normal mode where everyone "does
their job" and project manager is hands off is not adequately reliable for these systems.

My initial idea on this job has been to use a Wet Pipe System above the Freezer with ESFR Dry Pendents (Class IV in rack to 20'). Due to the exorbitant cost of the ESFR Dry Pendents I'm letting my thinking expand to possibly running Single Interlock Pre Action inside the Freezer ...since the Freezers are already up (yeah...I know !!).
