Dometic Cool-Ice Iceboxes, such as the Dometic Cool-Ice CI-55, are the perfect cooling solution for when power is not readily available. Features including a thick, refrigeration grade foam insulation and the 'Labyrinth Seal Design' combine to achieve longer lasting ice. Also, thanks to its rotomoulded design, there are no seams where heat can enter or cold can escape! Cool-Ice iceboxes are extremely strong, durable and easy to clean. Their robust design makes them ideal for continuous exposure to weather, especially on boats. The CI 55 icebox comes with strong ergonomic polyethylene handles that helpfully double as tie down points for securing the icebox. The Cool-Ice units are equipped with extremely effective insulation, and once the cool packs or ice cubes have been placed inside, they will keep groceries, fish, bait and wild game fresh. Depending on use and weather conditions, this can be for several days at a time! Ultimately, every single detail of these boxes, made from impact resistant and seamless plastic, is designed for the toughest conditions. This trusty icebox comes with strong and thick refrigeration grade foam insulation with unique labyrinth seal design that holds the cold air inside and hot air out for longer.
