In Leipzig, KRAMER insulation technology was commissioned by Bilfinger to insulate a heat storage unit for the city of Leipzig, including both the outgoing and incoming pipes.

The heat storage unit has a spiral design. In other words, it rotates upwards like a spiral. The storage unit is roughly 60 m tall and boasts a capacity of 43,000 cubic metres.

One of the challenges encountered during the project was to meet the architect’s specific requirements regarding the actual appearance of the storage unit. The customer did not want a bland “coke can” design, seeking a more visually appealing alternative for the metal tower structure. Both the colour of the steel sheets and the rings between the sheets were precisely defined and coordinated with the appearance of the rest of the buildings around the site.

The exceptional quality and work displayed by KRAMER insulation technology proved so convincing that we were entrusted with additional on-site projects.

Cooperation with KRAMER's on-site manager was a delightful experience. Throughout the project, it was always possible to discuss issues "directly and unbureaucratically", enabling us to promptly address any special requests.
