Re: SPRINKLERS INSIDE OVENS

[rongreenman .]

I was visualizing circuit board drying ovens but I see other ovens with
materials inside that could combust at this temperature. Tyco has a formula
for determine how long a dry pendent needs to be to keep from transferring
freezing temperatures to a wet supply. Perhaps that can be used to figure
the rate heat would dissipate from your drops and not be to high for your
system. If expansion is your only consideration then a PRV at the riser or
main drain will fix that. And finally put a control valve on the drops as
you will be replacing those heads often. If I recall, annually if links and
every five if bulbs.

RE: SPRINKLERS INSIDE OVENS

[Craig.Prahl]

NFPA 86 dictates the types of ovens which require internal fire suppression.  
There are all kinds of ovens other than just the type for cooking.

I believe this question has been on the forum before and the question was WHY 
does one need to put sprinklers in an  oven, especially if the oven temperature 
is only 300 degrees.
Wet, dry, or pre-action, the problems are 1) the pressure rating of the 
components at the operating temperature of the oven, and 2) what happens to 360 
degree liquid water when you decompress it?

I have a worry,
I need to install sprinklers inside an Oven that work at 300°F. I know that I 
need to use a sprinklers 360°F or high.
But this system is tie to a same roof grid. And my concern is that what happen 
with the heat, in the water, it temperature could go up to roof grid system, or 
over pressurized my pipes system. What I need to do??..
Or anyone have some recommendations??.

preaction systems are what I see for this
