Winegrowers Supplies - Stainless Steel 'Rectangular' fixed capacity Tanks for fermentation and storage
If these tanks are not full then, to prevent oxidation, you need to put a 'blanket layer' of CO2 gas (from a cylinder) over the liquid; CO2 is heavier than air.
I can supply a ZERO Pressure Controller for automatically supplying CO2 to the airspace at the top of a tank.
Rectangular tanks are considerably more expensive than normal cylindrical tanks, but if you have limited space in your cellar then they can be the best choice.
Available as single tanks, also stacking or compound; compound appearing like a single tank but with an intermediate partition.
