Uptown Arlesheim Project
Smart design that maximises efficiency in minimal space.

Introduction
The Uptown Arlesheim development near Basel represents a forward-looking investment in sustainable energy infrastructure.
Bringing together an association of 25 heating networks, the project is designed to deliver reliable, efficient heating and cooling across multiple buildings while aligning with Switzerland’s stringent energy regulations.
The Hydronic Challenge
The expansion required the installation of 26 x 4000-litre vessels within a highly constrained technical space. This posed a significant challenge in ensuring safe pressurisation, reliable degassing, and water quality management without compromising available space or operational accessibility.
Solution
IMI developed a compact and high-performance system tailored to the site’s unique requirements. The solution integrated:
- Transfero TI and Transfero TGI pressurisation units for dynamic pressure management
- Aquapresso AG water treatment to maintain system quality
- Zwischengefäss DG and Vento VI for advanced degassing functions
- Zeparo ZUM and Ferro-Cleaner for air and dirt separation
- Statico SU expansion vessels and safety valves DG/F to ensure operational safety
By leveraging the technical benefits of minimal space requirements and modular integration, the IMI solution provided the reliability and flexibility necessary for long-term system performance.
Customer Value
The project secured the continued functionality of the heating network, enabling stable and efficient operation despite spatial constraints. This solution was “absolutely necessary” for the system to function and ensures sustainable operation, using wood sourced from around 20 municipalities as the primary energy source.
