If it's a freezer box in a building the Viking K14 ESFR's are the best bet, especially if the roof deck is combustible because only one compliment of pipe is needed. The only issue with the Viking head is the flat plate is designed to fit against a flat surface and every freeze we have seen there are ribs in steel sheeting every 4-6". We have had to foam the hole around the pipe and add insulation to drop above the freezer because of ice forming on the drop. If it's a freezer building with the insulation on the roof Quell is probably the only game in town. It is designed for Class II and is usually adequate for frozen food. Victaulic keeps trying to say that their head will work in a freezer but the problem is doing the water delivery time calculations. Tyco says their calc program is UL Listed only with their K17 Ultra so I guess technically the program isn't valid for another sprinkler. Victaulic has told me that FM will do the calc's if it is an FM insured property. I have inquired to FM about doing the delivery calc's and got "HUH?" in reply.
I have heard that Viking is coming out with a K25 ESFR dry pendent.

There are some CMSA dry/preaction options out there, Victualic has a couple and they will cover in some circumstances plastics etc depending on storage heights etc. Mike Morey, SET, CFPS Sprinkler Designer BMW Constructors, Inc.
