Permafrost thermal storage for cooling

Sunamp Permafrost thermal batteries are space-saving, cool storage that reduce energy consumption and carbon emissions associated with air conditioning, district cooling networks and freezing.

Providing highly efficient, low carbon cooling, Permafrost thermal batteries are up to four times smaller than any equivalent thermal store thanks to our energy-dense phase change material, Plentigrade. The thermal batteries can be filled with different PCM formulations to suit cooling and freezing temperature applications.

Many energy sources

Permafrost thermal batteries are designed to integrate with heating, ventilation, air conditioning and refrigeration (HVAC&R) equipment, and can be charged from a wide choice of energy sources including process and waste cooling, cooling networks and chillers powered by renewables. 

Modular and scalable, Permafrost batteries can be connected in series or in parallel to increase cooling storage capacity and resilience needed by commercial buildings, agricultural processes, cooling networks, and industrial-scale systems.

Different model sizes

Permafrost is our product range for cooling and will come in different sizes. 

Permafrost Mini is for commercial buildings needing cooling and reversible HVAC cooling and heating is available to order by contacting us directly. Permafrost models for homes and large-scale industrial settings will follow later in 2022.
