Freezer container power consumption
Freezer containers, also known as “Reefer” containers, play a key role in the transportation and storage of goods requiring precise temperature control. These containers are equipped with advanced refrigeration systems that allow temperatures to be maintained from -60°C to +35°C. One of the most important features of a refrigerated container is its power consumption. Let’s take a look at the factors affecting consumption and how to optimize operating costs.
How does a freezer container work?
Freezer containers use refrigeration units that include compressors, condensers, fans and insulation. These components work together to maintain the desired temperature inside the container. Modern refrigeration equipment, such as the MicroLink 3, is characterized by low energy consumption and efficient operation, which helps to protect the environment and reduce operating costs.
Factors affecting electricity consumption
- Temperature range: Freezer containers have different temperature ranges, from -60°C to +35°C. Electricity consumption increases as the temperature decreases. For example, “Super freezer” containers, which maintain temperatures down to -60°C, require more energy than standard containers operating in the -25°C to +25°C range.
- Insulation: good container insulation plays a key role in reducing heat loss and thus energy consumption. Containers with better insulation minimize heat exchange with the outside environment, which means the refrigeration unit does not have to work as hard.
- Outdoor conditions: energy consumption is also affected by outdoor temperatures. In hot climates, the refrigeration unit has to work harder to keep the temperature inside the container low. Conversely, in cooler conditions, the energy requirement is lower.
- Loading method: how the container is loaded can also affect its energy consumption. An evenly distributed load allows for more efficient air circulation, which makes it easier to maintain the desired temperature.
- Maintenance and condition of the equipment: regular maintenance of the refrigeration equipment is essential for its effective functioning. Clogged filters, worn seals or other technical problems can increase energy consumption.
How to reduce electricity consumption?
- Temperature optimization: set the temperature in the container to the highest possible value that still ensures safe storage of your goods. This avoids unnecessary energy waste.
- Regular maintenance: ensure regular maintenance of the refrigeration equipment, including cleaning filters and checking seals, to keep the equipment working as efficiently as possible.
- Use modern technology: invest in modern cooling units that have low energy consumption, such as the MicroLink 3 system mentioned above. These systems are designed to save energy while providing reliable performance.
- Load optimisation: make sure the load is evenly distributed in the container and does not obstruct air circulation. Proper air circulation is key to maintaining a constant temperature with lower energy consumption.
- Insulating materials: Use containers with quality insulation that minimizes heat loss and thus reduces the need for cooling energy.

What Are the Internal Dimensions of a 40 Foot Container?
A standard 40-foot dry shipping container has internal dimensions of 12,032 mm in length, 2,352 mm in width, and 2,395 mm in height — or approximately 39 feet 5⅝ inches × 7 feet 8⅝ inches × 7 feet 10¼ inches. These figures come from the published specifications of major shipping lines and align with the ISO 668 international standard for Series 1 freight containers. The internal capacity is roughly 67.7 cubic meters (2,390 cubic feet).

A standard 40-foot shipping container has internal dimensions of approximately 12.032 meters (39 feet 5⅝ inches) in length, 2.352 meters (7 feet 8⅝ inches) in width, and 2.395 meters (7 feet 10¼ inches) in height. These internal dimensions are significantly smaller than the external dimensions because the corrugated steel walls, structural frame, corner posts, and the floor system—composed of plywood and steel—occupy valuable space intended for cargo.
What Is the Shipping Cost for a 40ft High Cube Container?
The shipping cost for a 40ft high cube container is not a single number — it is a layered calculation spanning purchase price, international ocean freight, and local ground delivery. A used 40ft high cube container typically costs $1,550 to $5,500 to purchase, while a new one-trip unit runs $2,800 to $9,000 depending on condition, location, and whether delivery is included.
Shipping container types
Roughly 80% of everything you own traveled to you inside a steel box. Shipping containers—also called cargo containers, ISO containers, or “conex” boxes—are the backbone of global trade, carrying about 90% of the world’s non-bulk cargo across oceans, rails, and highways. Yet a “shipping container” is not one single object. It is a family of specialized steel boxes, each engineered for a specific kind of cargo: some vent, some freeze, some open from the top, and some have no walls at all.
