Energy box

A sustainable development project: the energy box

Replacing old energy sources and sustainably promoting Co2.

That is the aim of the energy box. As an owner-managed company, ANTROK develops new technologies as part of its innovation efforts. Our latest development is the energy box: a container-sized energy solution that can be individually integrated into the cityscape to supply large residential units with heating and cooling. Operators save costs, comply with environmental regulations and meet legal requirements better than with any conventional solution such as oil or gas heating systems.
