So you’ve decided you want to do a “closed” transfer from your Chronical to your Ss Brite Tank, this guide will give you some basic guidelines on how to accomplish this.
First, make sure that your Chronical Fermenter and Brite Tank are on the same plane (i.e. the brite tank is not sitting higher than your fermenter).
This helps significantly with ensuring you're not using too much pressure to transfer your beer. Remember, for every foot, your receiving vessel is above the vessel being drained, you'll have to use an extra 1/2 psi (roughly) to get the beer to transfer. Now basically if your Brite Tank is sitting on a work bench and your fermenter is on the floor, you’ll already have to use about 1.5 psi just to overcome the height difference, so it’s better if they’re on the same level (or have the fermenter above the level of the brite tank).
Make sure before you start any transfers that you have all of your lines, fitting, gaskets, and receiving vessels properly cleaned and sanitized.
Next, you’ll want to purge your lines and brite tank with CO2 (see this article on how to purge your brite tank) to ensure your beer will not be exposed to O2 (after all that’s why you’re doing the closed transfer in the first place).
Once everything is purged, you can begin transferring your beer. You should be very careful to not push the beer with more than about 2 psi otherwise, you risk harming your fermenter! (For more information, see this link)
Many people have been unscrewing the PRV to vent the vessel. Instead of unscrewing the PRV every time you transfer, you can simply crack open the TC clamp on the top and let the lid gently rest on the top (slightly pushed off to the side and without the clamp on it) so that it will allow the gas to escape as you fill the vessel up.
Since your Brite Tank was purged with CO2, you'll be filling from the bottom up, and CO2 is heavier (denser) than O2, there will effectively be a blanket of CO2 gas on top of the beer which protects it from being exposed to O2 as you fill. In fact, the CO2 is what'll be escaping as you fill your tank up.
