Use the exact model specification
Request external and clear internal dimensions, door opening, floor height and equipment position. Confirm standard height or High Cube. Dry-container reference dimensions are not a reefer specification.
Compare pallets using their loaded footprint. A 48 × 40 in pallet is common in the United States, but confirm the actual base, overhang and handling equipment. The pallet size does not establish its load rating.
Keep the airflow route usable
Follow the manufacturer’s load-height limits and airflow instructions. Shelving and dense packaging can alter circulation. A geometric maximum pallet count is not a temperature-controlled loading plan.
State product type, incoming temperature, target range, loading frequency and ambient conditions. Holding chilled goods and cooling a warm load are different duties.
Check power and commissioning
Obtain voltage, frequency, phases, current, connector and protection requirements from the allocated refrigeration system’s nameplate and documentation. Have a qualified electrician verify compatibility with the US site supply. Confirm required product approval, electrical permits and inspections with the authority having jurisdiction; an international refrigeration specification alone does not establish acceptance of the stationary installation. Identify transformer, generator or cable requirements before comparing delivered prices.
Include ground support, access, commissioning, alarm monitoring and breakdown response in the written scope. Preserve the manufacturer’s access and ventilation clearances.
Questions before you choose
Is the interior the same as a dry container?
No. Insulation, refrigeration equipment, floor construction and model details change the clear space and usable loading capacity.
