  • Meet high cooling requirements without additional chillers

Compact, transportable, peak load capacity | sp.ICE ice storage in a container

The sp.ICE is a modular ice storage system with compact dimensions and very short charging times, making it a high-end product for use as a full-load storage system. This makes the sp.ICE particularly economical to operate in applications that need to cover peak cooling loads during the day when electricity tariffs are high.

The sp.ICE heat exchanger

Patented ice storage system made in Germany

At the heart of the sp.ICE is a new development: modularly combined capillary tube mats create a large heat transfer surface. This enables the sp.ICE to freeze water at an average production temperature of -2.5°C. The energy stored in this way can be called up precisely at times of peak demand.
