Solar Coolbox

For Global Cooling, we developed a solar coolbox, a demonstrator showcasing the potential of their patented free-piston Stirling cooling technology. This technology allows a highly energy efficient coolbox design, enabling the coolbox to be powered by a solar panel.

The coolbox is compact and portable, as it does not require a battery. The 19 Wp solar panel is integrated in the design and shields the coolbox from the sun. Furthermore, the coolbox components and materials were designed for easy recycling. The solar coolbox can be used to to store food, medicine and other perishable goods. It is especially suitable when supply of electricity is absent, limted, or irregular, for instance in remote area's, in the car, or at the beach.

Global Cooling has licenced their technology and produces Stirling Ultracold freezers.
