Integrating renewables on a massive scale

Ice energy store systems are an attractive heat source for brine/water heat pumps. In this intelligent system, heat source management ensures efficient interaction between the ice store, solar air absorber and heat pump.

Collectors up to 10.3 square meters in size are ideal for applications in local heating networks such as bioenergy villages, and also for generating industrial process heat. The casing, vacuum tubes and mounting frames are delivered pre-assembled.

Integration into the building management system: Vitocontrol and ViScada

Vitocontrol 100-M is the central control unit for mono mode and multi mode energy systems in municipal and commercial environments as well as in apartment buildings. ViScada is the ideal web tool for visualization and easy analysis.

Distribute heat efficiently: from simple to complex with PEWO

The expectations of a very broad range of ambient temperatures are becoming more and more specific. This is why we work with the PEWO modular system. We use it to configure the right equipment and systems for every heating and cooling task.
