    You guys are legends, thanks for the help!
    I'm also looking for a fridge suitable for the spike, so pictures would be great.

    @Meddo,
    Current configuration of the fridge. Not super happy with this layout, prefer the sight tube vertical, that requires me to have the valve above the tube with a blank on the bottom (good for yeast harvest, not so much for dumping trub in a controlled manner). Need to adjust the leg supports/get some extensions for the front and it’ll be sweet. Once I’ve transferred this brew, I’ll be taking the feet off and looking for some threaded rod or the like to fix it up.

    Cheers,

    H.

    STC controlled fridge has no issues holding temp in Nth QLD, or chilling down to 2 odd deg either. Pretty happy with the FB Marketplace for this pickup :)

    Nice one @Hubert, that looks like a more appropriately sized fridge for the unit. My commercial jobby is 600L but a lot of that is width/depth that doesn't help as much as height.

    I've just knocked up some leg extensions - 42 mm square pine and 3/8" furniture studs and t-nuts. Just pitched a double-batch of a lager intended to be a Munich Helles, dumping trub and yeast is a priority for this batch and since it won't be dry-hopped I left off the dry-hop airlock and put the extensions and sight glass / valve on it instead.

    Using a 2" diaphragm valve for flow control when dumping the yeast and trub, unfortunately it's bloody long and adds a heap to the height requirement. I'm also a little bit skeptical as to how well it will work since it requires so many rotations to open and close - I'm a little worried that I'll need to open it right up to get it flowing but then won't be able to shut it off quickly enough. One way to find out though...

    So I'm having a little trouble working how big I need the fridge to be. @Meddo what's the internal width and depth of yours? looks like a good fit?

    Setup looks good @Hubert!

    Yeah, that’d hurt a bit... Mine drinks mine, so it was a win for her as well I guess.

    It's finally here! Ended up with the pressure kit, pickup tube, few extra 2" and 1.5" addons, and some tubing all up for $1078 so not too different to what's on the Aussie market with pressure fermenting. Most of that was the USD conversion fee.
    Seems like a really solidly built unit!
    Brewing tomorrow so hopefully, have it going by tomorrow night.
    Have you guys noticed a difference in the end product with the pressure ferment, i.e reduced esters and fusels at higher temps, quicker fermentations or anything? I'm doing an English ale tomorrow so not sure if I should just ferment as normal, or increase temps because of the pressure.

    Congrats!! Absolutely love the build quality of mine.

    I have only done one pressure ferment so far, it was an IPA and did ferment quite quickly (4 days as opposed to the usual 7). Good on that note and there weren’t a whole lot of ester losses that I could perceive.
    Check out the BeerSmith podcast https://itunes.apple.com/au/podcast...nn-beersmith/id398500515?i=1000400084905&mt=2 for some more info. From what I’ve heard/read, the pressure ferment is mainly aimed towards getting lagers fermented out quicker and at higher (Ale) temps, not some much an issue with Ales as they generally get done fairly quickly anyway.
    Transfer to keg was a little harder as the beer was already carbed, so a closed transfer is essential. I hadn’t quite nailed down my process when I did this one, so it took a while amongst all the foam :( End product was still a nice beer that the traditional lager drinking FIL drank without complaint.

    Cheers,

    H.

    Well done mate, sweet looking setup - what's the fridge you're using?

    Haven't done any pressure fermenting yet as I don't have a spunding valve that I can trust. For me I'm not too concerned about doing the fast lager high pressure thing, but as I continue my lager-brewing education I would like to try the traditional German cold fermentation with a bit of top pressure to approximate the hydrostatic pressure in big commercial vessels.

    Thanks guys! So stoked on the purchase.
    I managed to get a commercial fridge off a mate who's a fridge mechanic.
    I might give the pressure ferment a go on this one just for fun. Will report back

    Hey @lespaul, what's the make/model of that fridge? And internal dimensions if it's not too much trouble?
