Used reefer container manufacturers

The cooling unit is the heart of the container. You must request a Pre-Trip Inspection (PTI) report dated within the last 30 days. This report confirms the machinery (usually Carrier, Thermo King, or Daikin) can reach and maintain set-point temperatures from -30°C to +30°C. Ensure the compressor, condenser coils, and evaporator fans are free from excessive corrosion and that the microprocessor controller is fully functional without active error codes.

For cross-border transport, the container must be Cargo Worthy (CW) and possess a valid CSC (Container Safety Convention) plate. Inspect the interior T-bar flooring for damage that could obstruct airflow, and check the stainless steel or aluminum interior liners for punctures. The door seals (gaskets) must be airtight to prevent thermal leakage, which significantly impacts energy consumption and cargo safety.

Verify the polyurethane foam insulation thickness (typically 100mm) and check for 'delamination' or bulging on the side panels, which indicates insulation failure. Regarding power, most units operate on 3-phase 380V/460V at 50/60Hz. Ensure the power cable and plug are intact and meet international industrial standards to prevent electrical hazards during transit or on-site operation.

If using the container for food, ensure it meets HACCP standards for cleanliness and is free from previous chemical contamination. For pharmaceuticals, the unit should support GDP (Good Distribution Practice) requirements, including temperature data logging capabilities and calibrated sensors to provide a verifiable 'cold chain' audit trail.

The biggest risk is undisclosed mechanical failure or 'gas leaks' in the refrigerant system. To mitigate this, always source from reputable suppliers on Made-in-China.com who provide third-party inspection videos of the unit running. Another risk is refrigerant type compliance; ensure the unit uses eco-friendly refrigerants like R-134a or R-404A, as older gases may be banned in your destination country.

Negotiate for a warranty period on the compressor (typically 3-6 months for used units). Use Secure Payment services to ensure funds are only released after the Bill of Lading (B/L) and PTI certificates are uploaded. Request a high-resolution video of the specific unit's serial number and the controller screen showing the temperature dropping in real-time.

Used reefers are often shipped as 'Non-Operating Reefers' (NOR) to reduce freight costs if they are empty. However, if you are shipping temperature-sensitive goods inside, you must book 'Active Reefer' service, which is significantly more expensive. Ensure the supplier provides a wind and watertight (WWT) guarantee to prevent moisture ingress during sea transit.

Many countries have strict customs regulations on 'waste' vs. 'second-hand goods'. Ensure the commercial invoice clearly states the unit is a 'Used Shipping Container' with its unique prefix and serial number. Check for import duties and environmental taxes related to the refrigerant gas pre-charged in the unit to avoid unexpected costs at the port of entry.
