Our Ice Box Conversion Kits are designed to add refrigeration to an existing ice box, or to replace a previously installed conversion kit. Many of our competitors kits use a stamped plate aluminum evaporator, which are notoriously thin walled and easy to puncture. If a hole develops through puncture or corrosion the evaporator is non repairable and must be replaced. They are also known for developing leaks at the copper tubing to aluminum joint, as the disimilar metals tend to corrode. Our evaporators are a proprietary aluminum extrusion with 1/4" copper tubing snapped into channels on the back, making the evaporator extremely durable as well as repairable, with no aluminum to copper joint to worry about.

Our Conversion Kits are designed to be DIY installations with detailed installation instructions included.

Powered by 12 or 24 volt DC: Our easy to install refrigeration kit will convert a standard ice box to a highly efficient system that runs off your batteries. The basic kit is made up of three parts: First, the evaporator plate, which is installed in your ice box and provides the cold surface to cool your product. Second, the compressor/condensor unit which is mounted outside the box as close as possible, but can be up to 20 feet away. This is connected to the evaporator with copper tubing. Third, the cold control (thermostat) is mounted in the ice box and allows you to select refrigerator or freezer temperatures.

Dura-Coil Evaporators: Three standard styles are available: flat plate, box and blower style. The flat plate style can be used for refrigerator or freezer applications. The box style allows you to have a small freezer compartment inside the refrigerator. The blower style uses two plates sandwiched together with a 1" air gap. A small fan pulls air between the plates and blows out into the fridge. This style provides the most amount of cooling in the smallest size. The fan offers two main advantages, less temperature difference between the top and bottom of the fridge compartment, and better heat exchange between the air and the evaporator plate, resulting in greater efficiency. The Sea Freeze Dura-Coil evaporator plate design allows you the flexibility to order a size that fits your cooling load and box size. We can calculate how much plate you need based on the size of the box and thickness of the insulation. The Dura-Coil starts with an aluminum extrusion that is 3.5" wide, the sections snap together to achieve your desired width, up to 18 inches. The length can be 12 to 48 inches. Next a copper tube coil is formed and is then snapped into the aluminum extrusion giving you an evaporator that is puncture and corrosion resistant.

Compressor/Condenser unit: The heart of a refrigeration system is the compressor. It pulls low pressure gas from the evaporator then compresses it into a high pressure gas that passes throught the condenser coil, releasing the heat that was absorbed in the evaporator and condensing to a liquid. The compressor is driven by a powerful 3 phase brushless DC motor. Sea Freeze offers different sizes of compressors to meet your cooling requirements. For efficiency the compressor needs to be matched to the proper size of evaporator.

Condenser Choices: We offer your choice of air cooled, water cooled, or air-water cooled combination.
