The structure of a china freezer is the same as the structure of a refrigerator. It consists of three parts: the box, the refrigeration system, and the temperature control device.

The dual refrigeration technology of the freezer solves the technical problems that are difficult to overcome by a single refrigeration method so that there is no cooling blind zone in the cabinet. The 500mm super-wide shelf provides customers with a larger effective display area and more inventory. Osram's special lamps placed at the front of each shelf enhance the display effect of the items in the cabinet. The integrated foaming and firm and reliable steel frame foundation of the freezer make the cabinet better in heat preservation and the structure is more durable. The color steel plate cabinet with strong corrosion resistance increases the service life of the cabinet. The freezer's fully transparent glass side panels make the items in the cabinet clear at a glance and enhance the display effect of the items in the cabinet. The digital thermostat controlled by the microcomputer makes the temperature control of the items in the cabinet more accurate and the system more energy-saving.

solar dc freezer refrigeration technology also has dual refrigeration technology using a freezer, which is more practical and convenient than ordinary refrigerators in use.
