Permafrost Mini thermal battery

The Sunamp Permafrost Mini provides highly efficient, low-carbon cooling for commercial buildings and industrial processes.

  • Charges from multiple energy and cooling sources
  • Offers demand side management and shifts cooling loads to cheaper off-peak tariffs
  • Reduces pre-cooling time required in buildings
  • Cuts the volume of glycol needed in cooling systems

Lower Costs

A Permafrost Mini thermal battery is clean and fast to install.

In addition to your cooling system using less glycol, the running costs of a Permafrost Mini battery are low because mandatory annual maintenance and inspections are not required.


Modular and scalable, our thermal batteries can be connected in series or in parallel to increase storage capacity.

  • Combines with heating, ventilation, air conditioning and refrigeration (HVAC&R) equipment
  • Integrates solar thermal and solar PV systems with the existing cooling plant


Our Permafrost Mini batteries contain Plentigrade, our high-performance phase change technology and can be filled with different formulations to suit cold temperature applications.

For example, supplying peak demand capability of a city center cooling network to enable more buildings to be installed onto the network.
