30 Sep How Do Reefer Containers Work? Ensuring the Safety of Temperature-Sensitive Shipments

New and used shipping containers are being used to create idyllic homes, comfortable offices, extra classrooms and so much more. But, did you know that these sturdy boxes can be converted into refrigeration units to ensure the safety of temperature-sensitive items during shipment? How do reefer containers work and why are they necessary? In this article, the experts in container conversions, Absolute Containers, explain the working mechanisms behind reefer container cooling systems.

How Do Reefer Containers Work and Why Are They Necessary?

Before exploring the industries that rely on container cooling systems, let’s answer the first question: how do reefer containers work?

The Tech Behind Temperature-Controlled Shipping

Reefer containers are specialised shipping containers designed to maintain specific temperature conditions and are typically used to transport perishable goods such as fresh produce, meats, and pharmaceuticals, to name a few. These containers are equipped with refrigeration units and use a closed-loop system to circulate a refrigerant, which absorbs warm air from the inside of the container.

This warm air is drawn into the unit where it is cooled and then redistributed throughout the container, effectively cooling the interior space. The T-shaped decking has specially designed grooves that allow the cold air to circulate freely ensuring an even temperature distribution. Without these grooves, the produce at the bottom of the container might be unable to maintain the desired temperature. It is important to note that temperatures need to be monitored and controlled throughout the journey ensuring the produce doesn’t spoil.

Keeping the Cool Chain Intact

Reefers are extremely versatile having the capability of maintaining a wide range of temperature conditions. This flexibility is essential as different goods have different temperature requirements. Additionally, some products necessitate fresh air circulation, while others are sensitive to humidity. These containers are equipped to regulate all these factors, ensuring optimal conditions for preserving the quality of transported goods.

Industries That Rely on Cool Storage

• Medicines and vaccines – Reefer containers play a critical role in providing the pharmaceutical industry the means to transport life-saving medicines and vaccines at perfect temperature conditions.
• Food supply chain – Whether importing or exporting, reefer containers are used to ship fresh produce around the globe, keeping goods at a consistent temperature and ensuring they remain fresh.
• Dry cargo – To prevent wasting space and money by shipping empty reefer containers, refrigeration units can be turned off converting them into regular containers for dry storage.
• Film industry – The need for precise temperature control makes reefer containers ideal for the transporting and storing of delicate filming equipment, such as celluloid film.
