  • Do you request pressure certificate for Fermenter ?

    Hi, dear all, when fermenting under pressure, fermenter will see pressure above 15psi. Do you request pressure certificate(such as ASME) from supplier ?

    pressure vessel certification

    To make a pressure vessel a manufacturer must:
    -Submit engineering drawing for inspection
    -Have inspectors check at various stages of construction
    -Pressure test completed vessel

    Then they can put the asme rated pressure on the nameplate of the vessel.

    Glycol jackets can sometimes be certified separately by their manufacturer. The jacket could be rated for 30 psi while the tank itself is only atmospheric.

    This all costs money and so many manufacturers to not do this. Some will tell you that it is designed to safely handle higher pressure but not certified.


    If you do not have a pressure certification, it is illegal to operate the tank above 1 atmosphere (14.7 psi) You should have a PRV to guard against this.
    You could buy a higher rated PRV but it would be illegal.

    You could check with the manufacturer, but if the tank does not have a nameplate indicating asme certified pressure then it is unlikely to be certified since if they went through the trouble they would indicate it on the nameplate.


    The manufacturer may tell you that the tank is safe for higher pressure but not certified. then it is up to you to decide what pressure to operate at.
