Description
Sizing a 1500 L fermenter around real batch numbers
Fifteen hectoliters is an awkward number on paper. In US barrels, 15 BBL works out closer to 17.6 hL, so most of the 1500 L tanks we build carry roughly 1750 L gross volume — enough headspace for a vigorous ale krausen and still put a full 15 BBL into packaging. Tighter than that, and you are dumping beer off the top of the cone during high-cropping fermentations.
Construction and surface finish
Shell and dished heads are 3 mm SUS304 as standard. We quote 316L when the portfolio includes sour or mixed-culture beer, or when the plant\’s process water carries elevated chloride and pitting is a real risk rather than a theoretical one. Dimple jackets are laser-welded and pressure-tested at 6 bar before the 80 mm polyurethane goes on. Interior welds are ground and polished to 0.4 µm; exteriors get a 2B or brushed finish, depending on whether the tank is visible from the taproom or lives in a wet cellar where nobody cares.
Standard fittings: 60° cone, racking arm, oversized dry-hop port, CIP spray ball on a clamp, sample valve, and a 3 bar design pressure rating with a PRV matched to the vessel, not to the glycol loop.

Questions that come up before the PO
Do I need my own chiller? Yes. Jackets need 2–4 °C glycol at a flow rate we can confirm once you tell us your crash-cooling window.
Unitank or brite? If you package from the same vessel and carbonate in place, spec the extra fittings now — retrofitting a carbonation stone later means cutting a new port.
How is CIP handled? Spray ball coverage depends on pump flow and pressure at the ball. Undersized pumps are the most common startup problem we see.
Tell us your batch size, beer type, number of fermentation tanks and available space. We can recommend the tank volume, cooling area and configuration for your brewery.

Although there were a few minor issues, thanks to Polly’s help, it looks brilliant and has brought my little distillery quite a few new customers.
Very good！！I see now in my texting to you that in my excitement over having the installation here in the USA I totally forgot to give you and the company of ACE a very big compliment on the quality of the whole Installation!! It all looks fabulous and the way you packed it in the container was extraordinary!! I am very impressed with your company and want to say a big thank you to everybody who worked on my order!!
We have been using this still for a few batches now making whiskey, gin and a few other spirits and we are very happy with the results so far. The gear works well and gives good control during distillation. The spirit comes out clean and consistent from batch to batch and we have gotten the flavor profile we were looking for. It has also been easy to operate and maintain. It has been a great addition to our distillery and I’d definitely recommend it to other craft distillers looking for reliable equipment.”
