ODM New 40ft Refrigerated Freezer Container for Sale Factory, Exporter
Product Description
Product Introduction
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.

Advantages
Lower Cost
The price of second-hand cold boxes is much cheaper than that of new cold boxes. For some small enterprises or logistics operators with limited funds, buying second-hand cold boxes can reduce the equipment procurement cost to a certain extent, thereby improving economic benefits.
Reliable Performance
After proper inspection and maintenance, the refrigeration and insulation performance of most second-hand cold boxes can still meet the basic cargo transportation needs. Many second-hand cold boxes are manufactured by well-known manufacturers, and their quality is guaranteed. Even after use, they can still work normally within a reasonable service life.
Frequently Asked Questions
Q1
What precautions should be taken during loading?
- When loading goods, pay attention to even distribution, avoid stacking too high or too dense, leave enough air circulation space, and prevent clogging of refrigeration equipment and vents.
- For goods with special packaging requirements, such as fragile goods, perishable goods, etc., they should be loaded in accordance with the corresponding packaging specifications to ensure the safety of the goods during transportation.
- Different types of goods cannot be mixed to prevent cross-contamination of odors and deterioration of goods caused by different temperature requirements.
Q2
What should be paid attention to in daily maintenance?
- Check the sealing of the box regularly. If the sealing strip is found to be aging or damaged, it should be replaced in time.
- Clean the outside and inside of the box to keep the appearance clean and prevent dust and debris from entering the refrigeration equipment to affect the heat dissipation and operation effect.
Q3
What materials are used to ensure the thermal insulation of the container?
The inner and outer wall panels are insulated with high-efficiency polyurethane foam. Polyurethane foam offers superior thermal insulation properties, significantly reducing heat exchange between the container interior and exterior environment to maintain stable temperatures.
Q4
How does the container structure resist harsh transportation environments?
The box structure utilizes a durable steel framework with exterior wall panels manufactured from weathering steel or stainless steel. These materials are selected specifically for high resistance to outdoor corrosion, weather wear, and physical impact.
Q5
What are the main components of the independent refrigeration unit?
The cooling system operates using an integrated refrigeration unit comprising a high-efficiency compressor, a condenser, an expansion/throttling device, and an evaporator. The compressor drives the refrigerant circulation to extract internal heat and continuously cool the box.
Q6
Why is the inner wall panel lined with stainless steel or aluminum?
Smooth aluminum or stainless steel plates are installed inside because they are food-grade, corrosion-resistant, rust-free, and easy to sanitize, ensuring strict hygiene standards during food and cold-chain cargo transport.
