Re: Freezer Cooler Single Interlock Pre Action

With only 20' storage, you have 1000 gpm. The ESFR system will be 1250 gpm so it should just be better or equal. As long as water supply can handle the extra 250 gpm then it should be good. Travis Mack, SET MFP Design, LLC "Follow" us on Facebook:

Re: Freezer Cooler Single Interlock Pre Action

Thanks Travis...great suggestion. I'll run the Calcs again and get a price on the 11.2 Dry Pendents. I'm laid out at 100 sq ft so design changes will be nil on drawings. I'm curious to see what my main and line sizes will be...I'm 4-2-4 now so it should be close. Atlantic Realty and Building,

Re: Freezer Cooler Single Interlock Pre Action

You are talking Class IV to 20'. I assume double row racks, 8' aisles, non-encapsulated. That is 0.495/2000 for ceiling only sprinklers. If you max out at 100 sq ft, you are basically 50 gpm / sprinkler. If you use the 11.2 dry pendent sprinklers, you will have a starting pressure of about

Re: Freezer Cooler Single Interlock Pre Action

Thanks Guys for all of the responses. This will shed some more light on this project: Four weeks ago we didn't know this project existed. At the request of the owner we took on a "Cost Plus" project management arrangement to attempt to inject some sanity into the process. The building is a

Re: Freezer Cooler Single Interlock Pre Action

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

Also don't forget to drop down loop back up to prevent freeze blocks. FM has a detail to follow I believe Sent from my Verizon 4G LTE Droid On Sep 18, 2016 3:23 PM, Bruce Verhei wrote: That sounds taken care of. And Ron is correct. And the refrigerant type or N2 air dryer.

Re: Freezer Cooler Single Interlock Pre Action

How about a simple dry system (with an air dryer at the compressor), with the pipe basically laying on the floor (shimmed for draining), lines running down the longitudinal flue, and sprig up to a level or two of rack sprinklers? It would look like an asperagus field, but it might work! Brad On

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

Yes Laid uni strut on top of freezer to distribute the load then rod through the freezer. Had to seal each penetration of the rod. Nut and washer on the rod. Strut was then tired into structure on either side of the unit Sent from my Verizon 4G LTE Droid On Sep 18, 2016 3:03 PM, Bruce Verhei

Re: Freezer Cooler Single Interlock Pre Action

What is the structure of the freezer? Are the racks integral to that structure, or free standing? Could you support system from racks? Best Bruce Verhei Go 'Hawks Sent from my iPhone > On Sep 18, 2016, at 10:13, rongreenman . wrote: > > For once we have s post

Re: Freezer Cooler Single Interlock Pre Action

For once we have s post where a double interlock pre action is actually the proper system and our fellow forumite wants to use a single interlock. If you use a SIPA you'll have ice in your pipes before a head fuses. A DIPA WONT FLIW Wter into the piping until sprinklers are fused. On Sunday,

Freezer Cooler Single Interlock Pre Action

I have a very large Freezer/Cooler project that I am managing. 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
