Dometic Cool-Ice iceboxes, such as the Dometic Cool-Ice WCI 70, are perfect for any occasion where there is no power readily available. They will keep your ice frozen for days – up to ten days, depending on model usage and conditions. These robust iceboxes are ideal for continuous exposure to weather, especially on boats. The thick, refrigeration grade foam insulation and 'Labyrinth Seal Design' feature contribute to longer lasting ice. Its rotomoulded design means there's no seams where heat can get in or cold can escape! Cool-Ice iceboxes are also extremely strong, durable and easy to clean. This larger model of icebox comes with strong ergonomic polyethylene handles that double as useful tie down points to secure the icebox.
