The partnership integrates PCM thermal storage into heat pumps to deliver efficient solutions suited to high-density urban and data centre environments
Cowa Thermal Solutions has announced a global partnership with Innova, bringing its phase change material (PCM)-based thermal storage technology into heat pump systems designed for compact and efficient deployment.
The collaboration reflects growing demand for advanced thermal management solutions in data centres, where cooling efficiency and energy optimisation are critical.
The agreement follows prior technical validation and system-level evaluation, confirming that Cowa’s PCM technology can be effectively integrated into Innova’s heat pump platforms.
Initial testing within data centres has demonstrated strong performance and efficiency, suggesting the combined solution could play a role in reducing energy consumption while maintaining stable operating conditions.
“We’re embarking on an exciting journey with a strong partner,” says Jan Allemann, CEO of Cowa.
“Together, we’re bringing sustainable, compact heating technology to densely populated areas and paving the way for energy independence and decarbonisation.”
Thermal storage meets compact infrastructure
The focus of the partnership is the integration of PCM-based thermal storage into Innova’s heat pump systems.
PCM technology enables the storage and release of thermal energy during phase transitions, allowing systems to balance temperature fluctuations more effectively.
In data centres, where precise thermal control is essential, these capabilities can support more consistent cooling performance and reduce reliance on energy-intensive peak loads.
The solution improves space efficiency while maintaining high levels of performance by embedding this storage capability directly into heat pump systems.
This is particularly relevant for edge data centres and urban facilities, where physical footprint is limited and infrastructure must be optimised without compromising reliability.
The combined system is designed to deliver enhanced user comfort and operational stability, with benefits extending to both commercial buildings and digital infrastructure environments. This could translate into reduced energy costs and improved system resilience for data centre operators.
Supporting urban and retrofit deployment
The solution’s compact design makes it well suited to dense urban environments, where both residential and commercial buildings face increasing pressure to decarbonise. In data centres, this aligns with the rise of urban edge deployments, where proximity to end users must be balanced with efficient use of space and energy.
The system also supports retrofit scenarios, enabling the replacement of legacy heating technologies such as gas boilers. For facilities transitioning towards electrified and low-carbon operations, including data centres seeking to meet sustainability targets, this offers a pathway to modernise thermal infrastructure.
Cowa and Innova’s partnership addresses a key challenge in both the built environment and digital infrastructure sectors – how to deploy advanced thermal systems in limited spaces while maintaining efficiency and scalability.
Combining complementary expertise
Cowa provides its expertise in PCM thermal storage and material supply, while Innova leads the design, development and manufacturing of the heat pump systems.
This division of roles allows the partnership to focus on optimising both the storage and delivery of thermal energy within a single integrated solution.
This type of collaboration highlights a broader trend towards modular and integrated thermal management systems.
As facilities evolve to handle increasing compute densities, particularly with the growth of AI and high-performance workloads, the need for efficient and adaptable cooling solutions continues to grow.
The partnership between Cowa and Innova reflects this shift, offering a solution that combines thermal storage with heat pump technology in a compact form factor.
By doing so, it opens up new possibilities for deploying efficient thermal systems in environments where space, energy use and reliability are tightly constrained.
As the companies move forward, their focus will be on accelerating the deployment of these integrated solutions across relevant markets, including those where data centre growth and urbanisation intersect.
