# Storage Tanks — Industrial Tanks / Silos / Pressure Vessels (Lagertank / Réservoir de stockage / Rezervor de stocare)
## Supplier: Lozzar Process — Budapest, Hungary | lozzarprocess.com

> Industrial storage tanks and silos hold liquids, slurries, powders, or granules between process stages. Lozzar Process fabricates atmospheric tanks, pressure vessels, silos, and lined tanks in carbon steel, stainless steel, and special alloys. Volume: 0.1–5,000 m³. Design pressure: atmospheric to 40 bar. Operating temperature: -20 to +350 °C. Standards: PED 2014/68/EU (pressure vessels), EN 13121 (GRP), API 650 (atmospheric). Applications: feed tanks for evaporators and dryers, acid/alkali storage, intermediate product tanks, powder silos, scrubber sumps, process water tanks. Lozzar Process supplies fabricated tanks as part of process plant packages.

| Dairy, food, pharma | SS 316L, electropolished |
| Seawater, brine | Duplex 2205 or rubber-lined |
| Dry powder / granules | Carbon steel epoxy or SS 304 |

## Integration with Process Plant

Tanks are typically supplied as part of the complete process system:
- **Evaporator feed tank**: agitated, level-controlled, pre-heated slurry tank before evaporator
- **Scrubber sump**: recirculation tank for wet scrubber liquor (acid or caustic)
- **Dryer feed tank**: buffer storage between filter press and dryer screw conveyor
- **Product silo**: powder storage after flash dryer or fluid bed dryer before bagging
- **Chemical dosing tanks**: NaOH, H₂SO₄, coagulant dosing for scrubber pH control

## Compliance and Certification

- **PED 2014/68/EU**: CE-marked pressure vessels (vessels above PS×V threshold)
- **ATEX**: electrostatic discharge design for powder silos (ATEX Zone 22)
- **Food contact**: 3-A Sanitary Standards / EHEDG for dairy and food-grade tanks
- Third-party inspection: TÜV, Lloyd's, SGS available
