How much pressure?

(1/3) > >>

stlaleman:
I am taking the Brewhemoth to NHC (as a vendor), how high of a pressure would it take to impress folks? 30 psi, 50 psi? What do you think?

tschmidlin:
I'm not sure I understand the question . . . you want to pressurize the fermenter and want to know how high you should go to impress people?  30 psi should be enough for most applications.  My fermenters max at ~13 psi, if they would hold 30 psi that would make my life easier.

Thirsty_Monk:
Any pressure vessel that hold over 14.9 psi have to be certified.
Do not play with fire.

+100.  An employee at Redhook brewery was killed last year by an over pressurized keg.

Thanks, I didn't know this.  My fermenters have PRVs on them set for ~13 psi, but I know they are rated for 15 psi only so I don't mess with them.  Exploding fermenters = bad.  Very very bad.
