Closed loop transfer

[Laner]

Having problems with closed loop transfers.

I’ve had problems on both occassions despite repeated Youtube vid watching. Pressure fermenter higher than corny, corny at a lower psi than fermenter, beer line connected and transfer starts fine then as it slows I close the loop with the gas line. Then the problem starts… the trub starts circulating through the beer ( video to show )

What am I doing wrong?

I think we need to see a wider view of your process. And you are sure you have liquid to liquid and gas to gas? (silly question i;m sure!)

Is the beer in the pressure fermenter carbed? I'm thinking that your pressure differential between fermenter and corny might be too great, and as you connect the gas line a load of gas is shooting from fermenter to corny, and the trub is disturbed as the gas escapes like if you opened a coke bottle.

Yes the beer has been naturally carbed, at 15psi before transfer.
Lines are definetly correct, floating dip tube to floating dip tube and gas to gas on both occasions.

Ah just read the update, that makes sense.

I don’t have a pressure fermenter (so my have got this totally wrong) but I do closed transfer routinely. As you have the fermenter (correctly) higher than the keg, you only need the pressure difference to between the two to establish a syphon. Once that’s done, the pressure difference can (should) be equalised by connecting the the two gas posts. I’m used to doing a cold crash before transfer to settle the trub. Is that something you do?
