Colku DC-40 DC-50 built-in refrigerator is widely used in RV campers, boats and home-specific modification. This model is specially made of stainless steel 304 material, which is waterproof and anti-corrosion. Stainless steel is naturally not easy to breed bacteria, keeping the food inside the refrigerator clean and healthy. It is most suitable for use on yachts or ships at sea. Built-in design saves space. The input voltage is automatically converted to 12V or 24V, suitable for RV and camper modification. The high performance and low power consumption of the compressor are a highlight. The net capacity is 36 liters, and the dual-zone design (4L freezer, 32L fridge) allows you to store different types of food and drinks separately. Two colors (silver and black) and two capacities (36 liters and 47 liters) can provide you with more choices. In addition, we have pre-coated board materials for you to choose from.
