Description
250-Gallon Square Wine Storage Tank with Cooling Jacket
Square tanks usually come up for one of two reasons: the room is already built, or the tank has to sit against a wall without eating the walkway. A 250-gallon (946 L) unit at roughly 36 in × 36 in × 48 in overall occupies about the floor area of a pallet of barrels and still holds close to two tons of wine.
We build these as atmospheric vessels. Square geometry does not carry pressure the way a cylinder does, so there is no relief valve on the shell. You get a vented lid, a bubbler, or a fermentation lock, depending on the job. If your process needs head pressure, this is the wrong tank and we will say so before quoting.
Materials and fabrication
Type 304 is our default for wine and cider. We move to 316L when the customer runs high-acid must, chloride-bearing cooling water, or high-proof distillate. Interior is 2B mill finish with welds ground and polished; every internal corner is radiused to 3/4 in minimum so there is no crevice for lees to sit in. The dimple jacket covers two or three walls, 50 mm insulation, 304 cladding outside.

Cleaning and hookup
The bottom slopes to one corner so the tank drains dry without tipping. A rotating spray ball in the lid handles CIP; run your caustic at 140–160°F, then rinse and sanitize as usual. Glycol in and out are 1.5 in tri-clamp, and we label the return line so nobody crosses them on install day.
FAQ
Can I ferment in a square tank? You can, for low-volume work. Square panels flex more and corners are harder to verify clean. Most customers use these for storage, blending, and cold stabilization.
Do I need the jacket? If you are holding white wine at 45–50°F, cold stabilizing, or crash cooling, yes. Ambient storage in a cool cellar can work without one.
What do you need from me to quote? Volume, product type, glycol temperature available, fittings you already standardize on, and the doorway the tank has to fit through.
Tell us your batch size, wine type, number of tanks and available space. We can recommend the tank volume, cooling area and configuration for your winery.

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.”
