Climecon leased air terminal devices for an art exhibition – How circular economy can be utilized in ventilation

Climecon leased ventilation equipment to the Helsinki Art Museum for a temporary installation to support an international art exhibition while maintaining draft-free conditions.

In June 2021, the Helsinki Art Museum hosted an exhibition of work by German artist Katharina Grosse featuring large spatial installations. Massive silk canvasses spray-painted with artwork extended from ceiling to floor and required precise ventilation control to remain still and undisturbed. The museum's ventilation system needed temporary modification to accommodate the exhibition's unique demands. Climecon's specialists collaborated with the site's ventilation designers using CFD simulation to tailor the system, delivering 4,000 liters of supply air per second to the 12-meter-high arch hall. The tight contracting timeline meant ventilation alterations had to be completed before artworks were installed, requiring precise spatial modeling and careful equipment placement. The solution employed DINO-R displacement diffusers to distribute supply air into the occupied zone without creating drafts, keeping the canvasses calm and stable. The diffusers' adjustable throw patterns helped optimize airflows throughout the space. ROX nozzle ducts were positioned against windows to prevent fogging by flushing window surfaces with supply air. Climecon customized both products according to specifications and tested their performance in-house before delivery. This project demonstrated an innovative approach to temporary ventilation needs through equipment leasing—a departure from traditional acquisition models in HVAC. After the exhibition, Climecon reused the devices, exemplifying circular economy principles in the ventilation industry. Pekka Huhtela, Climecon's product manager, noted the importance of flexible operations in serving unprecedented customer needs.
