    ColdEh Spillover System Kit


    Turn that old icebox into true boat refrigeration, or get more space if that ‘ice tray’ bin-style freezer is just a little too small. A ‘spillover’ system is a refrigeration compartment box that is divided into two separate sections with a partition dividing the box into a freezer section and a refrigeration section. Typically the box is designed to provide a ratio of 1/3rd freezer space to 2/3 refrigerator space separated by a well-insulated partition.
    This kit provides the fan and passage venting for the partition, as well as a thermostat to trigger air circulation between the freezer and refrigerator spaces.
