FAQ About Refrigerated Containers
1. What is a reefer container and how does it work?
A reefer container, also known as a refrigerated shipping container, is a specialized transport unit equipped with a built-in refrigeration system to maintain precise temperature control during transit. It is designed for transporting temperature-sensitive goods such as fresh produce, frozen food, pharmaceuticals, and vaccines. The system operates continuously via power supply from ships, trucks, or on-site generators.
2. Are all reefer containers the same in design and performance?
No, reefer containers vary significantly based on application needs. For example:
• Dual refrigerated unit reefers feature two independent cooling systems for redundancy and reliability.
• Multi-temperature reefers allow multiple zones with different temperature settings within one container.
• Pallet wide reefers offer wider internal dimensions for improved cargo loading efficiency.
At Beiyu, we manufacture these variants to meet diverse global logistics demands.
3. What are the standard sizes of reefer containers?
The most common sizes for reefer containers are 20-foot and 40-foot lengths, both available in standard and high-cube versions. These dimensions align with ISO standards, ensuring compatibility with international shipping networks including sea, rail, and road transport.
4. How do dual refrigerated unit reefers improve cargo safety?
A dual refrigerated unit reefer is equipped with two independent cooling systems — a primary and a backup unit. If one fails, the other automatically activates to maintain stable internal temperatures (typically within ±0.5°C), preventing spoilage of sensitive goods like pharmaceuticals or perishable food. This redundancy makes it ideal for long-distance and cross-climate zone transportation.
5. Can I customize a multi-temperature reefer container for mixed cargo?
Yes, our multi-temperature reefer containers are engineered to support simultaneous transport of goods requiring different temperature zones. For instance:
• One zone at -18°C for frozen meat
• Another at 2–8°C for fresh dairy
• A third at 15–20°C for dry goods
These containers use insulated partitions and smart control systems to ensure thermal stability across compartments, making them ideal for e-commerce logistics and multi-store deliveries.
6. What makes your pallet wide reefer container different from standard models?
Our pallet wide reefer container features an expanded internal width (up to 2.556 meters) to accommodate wider pallets and improve loading efficiency. This design reduces stacking inefficiencies and enhances airflow, especially beneficial for large-scale shipments of fruits, vegetables, or industrial components.
7. Do your reefer containers comply with international standards?
All our reefer containers are manufactured in accordance with ISO/TC-104 standards, including:
• ISO 1496-2 (Refrigerated Containers)
• CSC Convention (Safe Containers)
• TIR Certification
They are certified by recognized classification societies such as ABS, BV, LR, and meet requirements for marine, rail, and road transport.
8. How do you ensure consistent temperature control during transit?
Our refrigerated containers are equipped with advanced monitoring systems that track real-time temperature, humidity, and compressor status. Data is logged for traceability and compliance with GSP, FDA, and WHO regulations. Additionally, intelligent controls adjust cooling output dynamically to minimize fluctuations and energy consumption.
9. What materials are used in the construction of your reefer containers?
We use high-grade materials to ensure durability and thermal performance:
• Exterior: Corrosion-resistant steel panels
• Insulation: High-density polyurethane foam (40–120mm thickness)
• Interior: Stainless steel lining for hygiene and easy cleaning
• Flooring: Aluminum-reinforced structure with drainage
• Corner fittings: Cast steel (JIS SCW480) for strength and load-bearing
This ensures long service life even in harsh environments.
