40ft High Cube (HC) Reefer Container Specifications

1. Physical Dimensions & Capacity

• External Dimensions: 40' L x 8' W x 9'6" H (12.19m x 2.44m x 2.89m)

• Internal Dimensions: Approx. 37'10" L x 7'5" W x 8'5" H

• Volume (Capacity): Approx. 67 to 68 cubic meters ($67-68 m^3$)

• Design: The interior is slightly smaller than a dry 40HC due to the heavy-duty insulation required to maintain internal temperatures.

2. Core Technical Features

• Temperature Range: Designed to maintain internal temperatures precisely between -30°C and +30°C, regardless of the outside environment.

• Insulation: High-density, closed-cell polyurethane foam injected into the walls, ceiling, and doors to prevent thermal leakage.

• Integrated Cooling Unit: A powerful, roof-mounted refrigeration unit (typically powered by 3-phase electricity) that handles both cooling and heating (if needed).

• T-Bar Flooring: The floor consists of aluminum "T-bars" which allow cold air to circulate underneath the cargo (bottom-air delivery), ensuring even temperature distribution throughout the large 40ft space.

3. Why choose the High Cube version?

The "High Cube" aspect is critical when dealing with reefers because:

• Airflow Optimization: The extra foot of height allows for better airflow over the top of the cargo, which is vital for perishable goods that require constant air circulation to stay fresh (like fruits or medical products).

• Stacking Efficiency: It allows for taller pallets or more layers of goods without compromising the air circulation needed to keep the product at a uniform temperature.

4. Critical Operational Considerations

• Power Requirements: These units require a consistent, high-voltage 3-phase power supply. If you are using this in a location without industrial power, you will require a "Clip-on" or "Underslung" Genset (Diesel Generator).

• Airflow Management: A common mistake is "overpacking." You must never stack cargo above the "Red Load Line" marked on the walls. If you block the airflow, the temperature will not be uniform, leading to potential spoilage.

• Pre-Trip Inspection (PTI): Always ensure a formal PTI has been conducted by the supplier. This confirms the machine, compressor, and temperature sensors are operating within factory specifications.
