Looks like Tyco finally came out with a listed anti-freeze solution. Anyone know the cost?

[SprinklerDesigner2]

I have been waiting for this.

The suppliers I have contacted know about it but as of yesterday they can't give a price.

Anyone get a price yet?

tyco, come on has to be fairly cheap!!!


Check page 181::

https://www.tyco-fire.com/e-catalog/Tyco-Fire-Protection-Products-PriceBook-01-19v2/#p=181

150 gallons only 5,400

Or the Sams' load 180 gallons for 7200

150 gallons only 5,400

So either $ 36 a gallon or
$ 40 a gallon

If I did the math right

So how does that compare to premix now????

Read closely. I believe it is only good for up to 40 gallons per system capacity, -10°F and only for non-storage areas.

It is not the cure all we have been needing, but it is definitely a step in the right direction.

I guess they were in a hurry to get to market

If you darcey calc it can you go more than 40?

 

[UFT12]

The limitation of 40 gal is propably not related to hydraulic performance as long as the correct values of density and viscosity are used, k factors are adjusted and water supply suffices. My understanding is that this premixed solution may not be as effective as pure water and therefore for large systems a fire could possibly grow larger as opposed to plain water. Consider it equivalent to exceeding the 60 sec limitation of dry pipe systems.

Systems using > 40 gallons can be used with this antifreeze solution. But the system must be calculated and the k-factor adjusted based on the design temperature and fluid density. That's how I interpreted the Tyco data sheet.

Seems correct based also on the requirement of 23.4.2.1.3, ed 2016. My bad, didn't think that through well enough.

Here is from the data sheet.

NFPA 13D
No limitations on sprinkler system volume. Antifreeze shall only be used in above-ground piping.

Dwelling Units Only
No limitations on sprinkler system volume in buildings only containing dwellings. Antifreeze shall only be used in above-ground piping.
NFPA 13R - Mixed Use Occupancies
Where buildings contain mixed use occupancies that are fed by a single sprinkler system, the system size shall be limited to 40 gal (151 L). Where a sprinkler system feeds solely dwelling units, the system size has no limitations. Antifreeze shall only be used in above-ground piping. Where a system feeds non-dwelling units, it shall be limited to 40 gal (151 L). If future building renovations result in occupancy classification changes, a fire sprinkler system evaluation must be performed to determine if any changes are required for the use of antifreeze.
NFPA 13
Buildings with occupancy classifications of Light Hazard and Ordinary Hazard Group 1 and 2 are limited to a sprinkler system volume of 40 gal (151 L). Storage applications using non-ESFR sprinklers are limited to a sprinkler system volume of 40 gal (151 L).

You can go >40 gallons in 13D systems, or 13R serving only dwelling units. In 13 systems, you can only go up to 40 gallon in Light and Ordinary hazard and storage systems using non-ESFR sprinklers. So, yes, you can exceed 40 gallons, but only in very limited circumstances. I believe this is a step in the right direction, but again, it is not going to replace dry systems in many areas. Hopefully, with this start, even better solutions will be developed.

Travis is correct and Tyco confirmed the system does have 40 gallon limits as per the listing.

You cannot use Darcy to exceed that. You do have to use Darcy where and if you go over 40.

Plus an expansion tank is required on all systems

Plus you have to hydro the system, drain all the water out including drops, install the LFP, and than hydro again,
