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:
- with agitator,
- with heating,
- with agitator and heating
everyone with capacity
- or 2000 liters.
The external sheet is polished mechanically, thanks to that is keeping aesthetic appearance and is easier to maintain.
