Refrigeration systems for reefer containers

Reefer containers are specialised refrigerated shipping containers designed for long-distance transport of temperature-sensitive cargo. Used in maritime shipping and intermodal logistics, they combine containerised freight handling with integrated refrigeration technology. 

One of the main advantages of reefer containers is their ability to move seamlessly between ship, port, rail and road transport. Because the refrigeration unit remains part of the container, the cold chain can be maintained throughout the entire logistics process.

This flexibility makes reefer containers an important element of modern global supply chains.

BITZER compressors are used in container refrigeration systems worldwide because of their reliability, efficiency and suitability for continuous operation under demanding ambient conditions.

Container refrigeration systems must operate reliably during long transport periods in changing climates. A reefer container needs to travel through tropical ports, cross oceans and continue by rail or truck without compromising temperature stability. Key requirements include:

• Continuous operation over several weeks
• Resistance to vibration and harsh marine environments
• High energy efficiency
• Precise temperature control
• Compliance with environmental regulations

Compressor technology plays a critical role in meeting these requirements while reducing operating costs and protecting transported goods.

Container cooling is used wherever temperature-sensitive goods need to be transported safely, reliably and efficiently across long distances.

• Fresh fruit and vegetables:
  Long-distance transport between continents requires stable temperatures and controlled conditions.
• Frozen food:
  Frozen products must remain consistently below the specified temperature throughout shipment.
• Pharmaceuticals and life sciences:
  Temperature-sensitive medicines and vaccines require reliable temperature management and monitoring.
• Seafood and meat:
  Fresh and frozen seafood products depend on uninterrupted refrigeration during international shipping.
• Specialty cargo:
  Flowers, dairy products and sensitive chemicals may require customised cooling conditions.
