Conversion Technology

At the heart of the PRISMA system is advanced machine and thermal storage technologies that store cold energy (or “coolth”, as we like to call it, the opposite of warmth) and return it for later use.

Utilising hi-tech heat exchangers custom designed by our engineers using specialist thermal design and simulation software, we are able to recycle this coolth energy with extremely low losses.

Ambient air is drawn in from the atmosphere to be cooled to extremely low temperatures, liquified and transferred to a vacuum insulated tank where it can be stored for long periods of time.

This whole conversion process is designed to run in reverse and discharge the stored air whilst recovering as much of the coolth to re-use on the next charging cycle.
