How Do Refrigerated Containers Work?
When it comes to transporting temperature-sensitive goods like fruits, vegetables, dairy products, meat, and pharmaceuticals, maintaining product quality is non-negotiable. This is where refrigerated containers come into play – the silent heroes of the cold chain industry.
Whether you’re looking for refrigerated container hire for a short-term project or exploring refrigerated containers for sale to add to your long-term logistics infrastructure, understanding how these containers function can help you make better decisions for your business.
At Conrail, we specialise in offering robust, reliable, and cost-effective refrigerated containers for hire and for sale across the UK.
What is a Refrigerated Container?
A refrigerated container, also known as a reefer container, is a specially designed shipping container equipped with an internal refrigeration unit. These containers are used to transport perishable goods that require a controlled temperature environment during transit or storage.
Unlike traditional containers, reefers maintain a consistent internal temperature, regardless of external weather conditions. This ensures that sensitive goods remain fresh and viable from departure to destination.
How Do Refrigerated Containers Work?
Refrigerated containers work using a sophisticated refrigeration system that includes three primary components:
- Compressor: The compressor compresses refrigerant gas and pushes it into the condenser.
- Condenser: The condenser cools the compressed gas into a high-pressure liquid.
- Evaporator: This liquid then travels to the evaporator, where it absorbs heat from inside the container, effectively cooling it. The gas is then returned to the compressor, and the cycle repeats.
Advanced control systems allow operators to adjust and monitor temperature, humidity, and airflow settings. Most modern refrigerated containers for hire and sale also feature remote monitoring, providing real-time alerts and data throughout the shipping process.
Key Features of Modern Refrigerated Containers
- Wide Temperature Range: From -30°C to +30°C, suitable for frozen and chilled goods.
- Durable Build: Corrosion-resistant stainless steel interiors and high-quality insulation.

- Versatility: Perfect for shipping or stationary use in warehouses, events, or construction sites.
At Conrail, our refrigerated containers for hire and refrigerated containers for sale are equipped with the latest technology to meet the evolving needs of your business.
Factors That Affect Performance
While refrigerated containers are highly efficient, their performance depends on several factors:
- Insulation Quality: Poor insulation leads to heat gain and fluctuating temperatures.
- Refrigeration Unit Maintenance: Regular servicing ensures optimal performance and prevents breakdowns.
- Loading Techniques: Proper airflow must be maintained by avoiding overloading or blocking the airflow paths.
- Journey Conditions: Extreme external temperatures or delays can impact the performance if the unit isn’t properly configured.
To ensure reliability, every refrigerated container hire from Conrail undergoes a rigorous quality check.
