The Dometic Air- & Water-Cooled Super ColdMachine cooling unit is powered by an advanced compressor which provides 25 % more cooling performance. The cooling unit can supply up to 15 cu. ft. (424 l) of custom cold storage. These cooling units run on 12/24 V DC power and provide refrigeration or freezing in tropical-water boating applications. Pair the cooling unit with a VD series evaporator or holdover power plate in a cold storage box or compartment which can be installed up to 15 ft. (4.57 m) away. The robust, corrosion-resistant stainless-steel construction is designed to survive the rigors of the marine environment while providing exceptional performance in hot and humid conditions, erratic or low voltage, or continuous use. The ColdMachine is equipped with self-sealing quick-connect fittings for easy attachment, and comes pre-charged and ready to install.
