Modular
Modular design that adapts to your specific needs. Whether you require heating or cooling, the system can be easily scaled by adding more modules, allowing you to tailor the solution for commercial buildings and district heating and cooling systems. Its flexible design ensures simple integration into existing infrastructure, reducing the need for large investments or demolition.

Scalable
Our Thermal Box is scalable, ensuring that it can be installed in both smaller and larger buildings and systems. By adding more modules, you can increase the system’s thermal output and storage capacity. The solution is ideal for retrofits or new builds, with easy installation both indoors and outdoors.
