Sea Frost's DC 5000 is designed to refrigerate boats equipped with large battery banks and alternative energy systems for battery charging. This direct drive system freezes holdover plates rapidly and maintains thermostatically controlled temperatures by operating on demand from battery power. It can also be operated when under power or generator to freeze holdover plates, eliminating battery draw.

The DC 5000 is powerful enough to run a three-plate, twin valve refrigerator/freezer and may be combined with the Engine Drive and/or air cooled Shore Assist for the ultimate in versatility and redundancy. The DC 5000 is a lightweight, compact, one-piece design.
