Sustained With Plentigrade
Sunamp thermal batteries are energy saving thermal stores containing Plentigrade: A high-performance phase change materials (PCMs) that deliver heating or cooling reliably, safely and efficiently.
This breakthrough technology was created in collaboration with the University of Edinburgh, ranked among the top 20 universities in the world, and the UK’s national synchrotron particle accelerator, Diamond Light Source.
Plentigrade is the remarkable PCM inside Sunamp thermal batteries which absorbs and releases thermal energy during a melting and freezing process in a similar way to the gel in a pocket handwarmer.
Freezing releases a huge amount of energy in the form of latent heat at a constant temperature.
Plentigrade guarantees high energy output and an almost unlimited lifespan, yet its composition remains unchanged. Sunamp hold multiple patents for Plentigrade PCMs.
