The tanks are made of acid-proof stainless steel. A characteristic feature of the tanks is the bottom of the drum in the shape of a cone, which allows it to be completely emptied. Each tank has a stand made of steel sheet reinforced with a cross, and a matching cover with a gasket closed on the buckles.
The tanks come in four variants:
- ordinary
- with agitator,
- with heating
- with agitator and heating
everyone with capacity 500 1000 or 2000 liters.
The outer sheet is mechanically ground, thanks to which it maintains its aesthetic appearance and is easier to maintain.
