Second hand reefer container manufacturers

When sourcing used refrigerated containers, the most critical component is the cooling unit (e.g., Carrier, Thermo King, or Daikin). Ensure the unit can maintain temperatures between -25°C and +25°C. Check the insulation integrity of the polyurethane foam walls; any 'delamination' or bulging indicates a loss of thermal efficiency. Additionally, verify the T-bar flooring is intact to ensure proper airflow, and inspect the door seals (gaskets) for any cracks that could lead to temperature leakage.

Request a Pre-Trip Inspection (PTI) report conducted within the last 30 days. A valid PTI ensures the microprocessor, compressor, and fans are functioning correctly. You should also ask for the Data Logger download, which provides a historical record of temperature stability. For high-value orders, hire a third-party inspector to perform a 'smoke test' to check for air leaks and a load test to see how quickly the unit reaches the set point (pull-down time).

The container must have a valid CSC Plate (Convention for Safe Containers), which acts as its 'passport' for shipping. If the plate has expired, the container must undergo an ACEP (Approved Continuous Examination Program) or a new survey. For food-grade storage, ensure the interior is stainless steel or aluminum and free from chemical odors or heavy staining. Ensure the refrigerant used (e.g., R134a or R404a) complies with the environmental regulations of your destination country.

Beyond standard shipping, these units are widely used for on-site cold storage for pharmaceutical companies, floral wholesalers, and food distributors. They serve as cost-effective alternatives to permanent cold rooms. Buyers often repurpose them for modular farming (hydroponics) or as temperature-controlled laboratories in remote mining or construction sites due to their durability and portability.

The primary risk is mechanical failure shortly after arrival, as warranties on used machinery are often limited. There is also the risk of structural damage (e.g., hidden rust in the corner castings) that may prevent the unit from being loaded onto a vessel. To mitigate this, use Made-in-China.com’s secured payment services to ensure funds are only released after the loading survey report is uploaded and verified.

Negotiate for a guaranteed PTI-passed status upon delivery at the port of loading. Request that the supplier provides a video of the unit running with a visible serial number and a thermometer reading. For bulk orders, negotiate a staggered payment schedule: 30% deposit, 60% upon presentation of the Bill of Lading and Inspection Report, and 10% after the unit is powered on at the destination and confirmed functional.

If shipping the container as 'Cargo' (Non-Operating Reefer or NOR), it can be used to carry dry goods, which reduces freight costs. However, if you need it to be 'Active' during transit, you must ensure the vessel has reefer plugs available and clarify who is responsible for monitoring the power during the voyage. Always confirm the voltage requirements (usually 380V/460V, 3-phase) match your local power grid or ensure a transformer/gen-set is included in the purchase.
