China New 40ft Refrigerated Freezer Container for Sale Product, Quotes

The box of an used reefer container is generally composed of a steel frame and inner and outer wall panels. The outer wall panels are usually made of weathering steel or stainless steel, which can resist corrosion and collision from the external environment. The inner wall panels are mostly smooth aluminum or stainless steel plates, which are easy to clean and maintain hygiene. The inner and outer wall panels are filled with high-efficiency thermal insulation materials, such as polyurethane foam, which have good thermal insulation properties and can effectively reduce the heat exchange inside and outside the box. It is equipped with an independent refrigeration unit. The refrigeration unit mainly includes components such as a compressor, a condenser, and an evaporator. The compressor is the core of the refrigeration system. It compresses the refrigerant into a high-temperature and high-pressure gas, which becomes a liquid after dissipating heat through the condenser, and then enters the evaporator after the pressure is reduced through the throttling device. The evaporator absorbs heat in the box, thereby achieving the purpose of reducing the temperature inside the box.
