The project consisted of two double walled and insulated shop-built tanks. The inner tank is 10′-0″ diameter x 16′-0″ high stainless-steel dimple jacketed, truncated roof, flat sloping floor with integral 32″ tall stainless steel stand. The inner tank is insulated with 2″ of polyisocyanurate foam and cladded with an all seal welded 12 ga outer shell that is 10′-5″ diameter x 16′-3″ tall.
These winery tanks were built from the top down using MIG and TIG welding processes. The dimple jackets on the inner tanks were spot welded and welded around the perimeter to seal the two pieces together. The dimple jacket is then inflated to create a void for the glycol to flow through. This jacketing allows the winery to control the temperature of the wine during fermentation all the way through bottling.
These tanks in total hold 18,800 gallons, enough wine to make 7,907 cases of wine or 94,887 bottles of wine.
