Reefer Container Guide for South African Agricultural Exports

Reefer (refrigerated) containers are essential for shipping perishable agricultural products, maintaining product quality through temperature-controlled environments. This guide covers reefer container types, temperature settings, monitoring systems, and best practices for South African agricultural exports.

Reefer Container Types

Standard Reefer Containers

Standard reefer container specifications:

• 20-foot containers: 20-30 pallets capacity
• 40-foot containers: 40-50 pallets capacity
• High-cube containers: Increased height for taller pallets
• Controlled atmosphere: Additional atmospheric control for extended shelf life

Commodity-Specific Containers

Different commodities require different container types:

• General purpose: For most fruits and vegetables
• Super-freezer: For frozen products
• Controlled atmosphere: For extended storage
• Multi-temperature: For mixed loads with different temperature requirements

Temperature Settings

Commodity-Specific Temperatures

Different products require different temperatures:

Citrus Fruits:

• Oranges: 3-5°C
• Lemons: 10-13°C
• Grapefruits: 10-13°C
• Soft citrus: 7-9°C

Deciduous Fruits:

• Apples: 0-4°C
• Pears: -1 to 0°C
• Stone fruits: 0-2°C
• Table grapes: -0.5 to 0°C

Other Products:

• Avocados: 5-7°C
• Meat products: -1 to -2°C
• Dairy products: 2-4°C
• Frozen products: -18°C or below

Temperature Tolerances

Temperature tolerances for quality maintenance:

• Strict tolerance: ±0.5°C for sensitive products
• Standard tolerance: ±1°C for most products
• Wide tolerance: ±2°C for hardy products
• Critical limits: Maximum/minimum acceptable temperatures

Monitoring Systems

Temperature Monitoring

Effective temperature monitoring requires:

• Multiple temperature sensors throughout container
