Single-phase Refrigerated Shipping Containers Vs. Three-phase Power
May 31, 2024
In the world of temperature-controlled logistics, refrigerated shipping containers are a vital tool for keeping perishables fresh over long distances. But when it comes to powering these containers, you might wonder: what's the difference between single-phase and three-phase power? And which one is right for you?
Understanding Single-phase and Three-phase Power
Before diving into refrigerated containers, let's break down the basics of single-phase and three-phase power. In layman's terms, think of electricity as water flowing through a pipe. Single-phase power is like having one pipe with a single stream of current. Three-phase power, on the other hand, is like having three pipes, each carrying its own current.
- Single-phase power is the most common type found in homes and offices. It's typically sufficient for powering household appliances and basic equipment.
- Three-phase power is a more robust type used in industrial settings and for powering larger equipment. It provides greater efficiency and can handle heavier electrical loads.

Single-phase vs. Three-phase Refrigerated Containers
Now that we understand the difference between single-phase and three-phase power, let's see how it applies to refrigerated shipping containers. Betta Storage Containers offers a wide selection of these temperature-controlled container units. Here's a quick rundown of the key differences between single-phase and three-phase refrigerated containers:
Single-phase refrigerated containers:
- Power requirements: These containers are designed to run on standard single-phase power meters, making them versatile for various applications.
- Size and capacity: Single-phase containers are typically smaller, like our popular 20-foot shipping containers, which are perfect for transporting smaller quantities of temperature-sensitive goods.
- Applications: Ideal for situations needing a reliable and cost-effective short-haul or temporary cold storage solution. They're also suitable for storing a wider variety of goods, as single-phase power can typically accommodate a broader range of refrigeration units.
Three-phase refrigerated containers:
- Power requirements: These containers require a three-phase power supply typically found in industrial warehouses or specialised facilities. If you don't have access to three-phase power, you might need to explore options like installing three-phase power or using a three-phase inverter to convert single-phase power.
- Size and capacity: Three-phase containers are generally larger than their single-phase counterparts. Betta Storage Containers offers these in 40-foot high cube models, providing ample space for large-scale cargo.
- Applications: Three-phase containers are ideal for long-haul transportation or storing large goods requiring consistent and powerful refrigeration. They're particularly suited for items that require precise temperature control, such as pharmaceuticals or frozen foods.
Choosing the Right Refrigerated Container for Your Needs
The decision between single-phase and three-phase refrigerated shipping containers depends on your specific requirements. Here are some factors to consider:
- The size and volume of your cargo: A single-phase container might suffice if you're transporting smaller quantities of goods. However, a three-phase container will provide the necessary space for larger volumes.
- The type of goods you're storing: Certain goods, like frozen meat or pharmaceuticals, require consistent and powerful refrigeration, which might be better suited for three-phase containers.
- Your access to power: If your facility only has single-phase power, consulting an electrical expert can help determine the best course of action. They can assess your needs and advise on whether converting 3-phase power from a single phase is feasible or if a single-phase refrigerated container is the most practical choice.
