Chiller to Move into New, Modern Facilities in Tuusula in Early 2026
Chiller, part of the Koja Group, is taking a significant step toward the future by relocating to entirely new, modern facilities in Tuusula in early 2026. The new headquarters, along with production and warehouse spaces, will be located in the Sula area, with Logian overseeing the implementation. The premises will span over 9,000 m², tailored to meet the needs of Chiller’s growing operations.
Focus on Sustainability and Energy Efficiency
The new facility is not only larger but also more environmentally friendly. The design emphasizes sustainability and energy efficiency, utilizing Koja’s and Chiller’s smart cooling, heating, and energy solutions. A similar Wave Solution has already been successfully implemented at Koja’s new factory in Jalasjärvi.
The building will be constructed in accordance with EU taxonomy and aims to achieve at least a BREEAM Excellent environmental certification, ensuring responsible and energy-efficient solutions throughout its lifecycle.
"This investment supports Chiller’s long-term growth strategy and creates excellent conditions for future development," says Chiller’s CEO Joonas Lius.
"With the new property, we can consolidate operations in one location, significantly invest in product development and production testing, and at the same time, strengthen our commitment to responsible business practices."

Chiller is part of the 90-year-old family-owned Koja Group, which is committed to remaining a family business for the next 100 years as well.
