Hi, is there any video of someone using it ? Just to get an idea of the beer botteling speed, foam generation, how to connect the lines, tune the PRV, etc. Thank you

BEST ANSWER: Hello Amaral, unfortunately we don't yet have a video of this system in use.
Will this fill to a set level via the PRV?
Marshall Harrington on Jul 23, 2020
BEST ANSWER: Yes and no. It can only make the bottle so full, yet I find that it over fills by a little bit at that point. So I just manually stop it when it gets to my target fill level. Also it doesn't stop sending beer into the bottle, so the beer will keep going into the bottom of the bottle and then the overflowing beer will go out the top and into the PRV and subsequently into the beer drip tray. I should also point out that the drip tray drain tends to not drain in my experience.

It fills great.
Yet there are multiple dead legs, that make cleaning and drying out between uses very labor intensive.
The largest dead leg is at the far end of the filling head where it extends far beyond the 4th filling tube. This makes cleaning, rinsing, sanitizing, and removing liquid before introducing beer to the filler very time consuming.
Also, the spring for the PRV is not stainless steel, so its important to keep the spring lubed to avoid rusting. It should also be noted that there are zero check valves, so it is important to keep the CO2 purge and counter pressure line pressure slightly less than the head pressure of the vessel you are filling from.

Love it!
Once you get used to it you are all set. I bottle using corny kegs so got creative to hook it up. This is a legit bottler and after getting the hang of it have quite an assembly line going at my winery & hard cidery. An understanding of counter pressure bottling will help tremendously so if you've been bottling with a single filler then you are ahead of the game! love the build quality and support.Had a few questions and they answered right away. Cheers & Thanks! Ian
