20ft Reefer Container Specification & Description

1. Physical Specifications

• External Dimensions: 20' L x 8' W x 8'6" H

• Internal Dimensions: Approx. 17'10" L x 7'6" W x 7'6" H (Note: Slightly smaller than a standard container due to insulation and the cooling unit).

• Capacity: Approx. 28 cubic meters ($28 m^3$).

• Weight: Heavier than a dry container due to the machinery and insulation.

2. Key Features

• Temperature Control: Capable of maintaining temperatures ranging from -25°C to +25°C (depending on the model).

• Insulation: The walls, floor, and ceiling are injected with high-density polyurethane foam to ensure maximum thermal efficiency.

• T-Bar Flooring: Equipped with a special "T-floor" design that allows cold air to circulate underneath the cargo for even cooling.

• Power Requirement: Requires a stable 3-phase power supply (usually 380V/440V) to run the cooling compressor.

• Data Logging: Modern reefers include digital controllers to monitor and record temperature history, which is critical for compliance (e.g., in food or pharmaceutical industries).

3. Common Uses

• Food & Beverage: Storing perishable items like meat, dairy, seafood, fruits, and vegetables.

• Pharmaceuticals: Storing temperature-sensitive medicines, vaccines, or chemicals.

• Events: Used as mobile cold storage for catering or festivals.

• Seasonal Overflow: Providing additional freezer/chiller space for warehouses during peak seasons.

4. Important Considerations for Hiring

• Power Source: Before hiring, ensure you have the correct 3-phase power connection on-site. If not, you may need a portable generator (GenSet).

• Monitoring: Since the unit is mechanical, you need a plan for regular monitoring to ensure the temperature stays within the required range.

• Maintenance: Ask the supplier if the hire includes technical support or maintenance, as refrigeration units are complex machinery.

• Pre-Trip Inspection (PTI): Always confirm that the supplier has performed a "PTI" to ensure the cooling unit is working perfectly before delivery.
