Customer story

New stainless steel tanks for a Danish chocolate milk factory

Gpi Tanks Poland engineered, manufactured and installed four 100 m3 stainless steel tanks for a Danish client. This project presented numerous challenges due to the client’s high demands and the extended timeline. Exceptional collaboration with the client enabled efficient organization of responsibilities both within Gpi and during the tank installation process.

Four 100m3 liquid storage tanks

Gpi delivered four tanks specifically designed for liquid storage. Each tank boasts an impressive capacity of 100 m3 and includes the following key specifications: 

  • Height: 17 m
  • Diameter: 3.5 m
  • Weight (empty): 11,500 kg

The tanks operate within safe pressure values:

  • Operating pressure: -5,0 / +5,0 mbarg
  • Jacket pressure: -0,0 / + 4,0 mbarg

Additional features and advanced solutions

The project involved more than just the tanks themselves; Gpi also provided additional elements:

  • Service platforms,
  • Cage ladders,
  • Communication alcoves.

The tanks were equipped with cooling jackets to meet the client’s requirements for precise temperature control and a specialized ventilation system, ensuring safe and efficient operation in a hygienic, closed environment. Specialized corridors under the tanks house an extensive installation that facilitates process operations.

Robust construction and high-quality materials

The tanks were manufactured using high-quality materials suitable for food contact:

  • Product contact surfaces: stainless steel 1.4404 / 316L,
  • Other structural elements: stainless steel 1.4307 / 304L and 1.4301 / 304.

Both top and bottom dished heads were designed in a conical shape, optimizing liquid storage, flow, and hygienic conditions.
The tanks are insulated with mineral wool to maintain optimal thermal conditions. Their design supports operations within a wide temperature range of -20°C to 98°C.

Transport & installation

Gpi Tanks Poland managed the entire project logistics, including transportation and on-site installation. The size of the tanks required meticulous planning and precise execution during transport. Specific requirements were addressed at every stage, ensuring the tanks meet the highest standards of quality, safety, and functionality. Advanced technologies and close client collaboration played a key role in the project’s success.
