Efficiency and Reliability for Data Centers
Data center requirements are continuously increasing, with energy efficiency, reliability, and sustainability playing a critical role.
Tailored cooling and energy recovery solutions
As server capacity requirements continue to grow and HPC, AI, and cloud computing become more widespread, data centers face increasing demands. Rising heat loads require a combination of liquid and air-cooling technologies, while energy efficiency and waste heat recovery are becoming ever more important. The cool Nordic climate provides excellent conditions for energy-efficient data center operations and enhances the performance of cooling solutions.
Koja Group delivers tailored end-to-end solutions from design and commissioning to lifecycle services. Innovative cooling and heat recovery technologies enable energy savings, environmental responsibility, and high performance in demanding data center environments, both for new construction and modernization projects.

Direct Liquid Cooling
Direct liquid cooling (Direct-to-Chip) is specifically designed for high-density data center environments where conventional air cooling is no longer sufficient. Liquid cooling transfers heat directly from server processors, enabling significantly more efficient thermal management compared to traditional air-based systems.
This technology allows for higher heat transfer capacity, reduced water and energy consumption, and improved system reliability, while supporting sustainability goals and future scalability.
Direct and Indirect Free Cooling Solutions
Direct and indirect free cooling solutions utilize the cooling potential of outdoor air to support data center cooling, maximizing energy savings and reducing operating costs.
Direct cooling solutions introduce outdoor air directly into technical spaces, while indirect solutions use heat exchanger to transfer heat loads outside, for example through a chiller system, without allowing outdoor air to enter the data hall.
Koja Group’s systems are designed to fully leverage Nordic climate conditions, ensuring energy-efficient and reliable operation throughout the year in all weather conditions.
Heat Recovery and Heat Pump Solutions
Heat recovery and heat pump solutions transform data center waste heat into valuable energy that can be utilized for building heating or fed into district heating networks.
Koja Group’s solutions improve overall system efficiency and support sustainability objectives. Advanced heat recovery equipment and heat pumps enable efficient heat transfer and energy recovery, reducing carbon emissions while delivering significant energy cost savings.
Precision and Close Control Units
Precision and close control units provide accurate temperature and humidity control for critical environments, such as data halls, equipment rooms, and electrical rooms.
Koja Group’s portfolio includes both air-cooled and water-cooled solutions designed with energy efficiency and flexibility in mind. These systems ensure reliable operation under demanding conditions and support comprehensive data center energy management.
