Product description Brand name and product description

This product was discontinued and replaced by the Stone Cold Systems (SCS) product.

The Stone Cold Solar was a prototype that combines active cooling and real-time temperature feedback to prevent the temperature changes that ruin vaccine loads during transportation. The unit features GPS tracking and run reporting from remote locations so that the necessary personnel can be notified if the temperature goes out of the preset range. In order to maintain functionality off the grid (during transportation), the Stone Cold Solar has a detachable solar panel that can be used to trickle charge the on-board battery.
