CaloCube

Replacing old energy sources and sustainably promoting Co2.

...That is the goal of the CaloCube. As an owner-managed company, ANTROK develops new technologies as part of its innovation efforts. Our latest development is the CaloCube: a container-sized energy solution that can be individually integrated into the urban landscape to provide large residential complexes with heating and cooling. In doing so, operators save costs, meet environmental requirements, and comply with legal regulations more effectively than with any conventional solution, such as oil or gas heating systems.
