What Is the Reefer Definition?
The term reefer is commonly used in the freight industry. It refers to a specialised type of container. Specifically, it's a container with temperature control capabilities. Reefers are essential for transporting perishable goods.
These containers keep products at a set temperature. This ensures the quality of items during transit and it is crucial for products like fruits, vegetables, and medicines.
How Do Reefers Work?
Reefers operate using a refrigeration unit. The unit is either pre-installed or attached externally. This unit maintains a specific temperature range. Some reefers can both heat and cool as needed.
They are insulated to prevent outside temperatures from affecting the cargo. This insulation helps in energy efficiency. The power source for these units can come from the ship's power supply or separate generators on trucks.
Why Are Reefers Important in Freight?
Reefers play a vital role in global trade. The transportation of perishable goods depends on them. Without reefers, goods could spoil before reaching their destination.
This rotting might cause significant financial losses, and it may also affect the availability of fruits, vegetables, and proteins. Reefers ensure that consumers receive fresh food all year round.
What Are the Benefits of Using Reefers?
Using reefers provides numerous advantages. They protect products from extreme temperatures. This is crucial during both the summer and winter months.
They also allow for longer travel distances without spoiling goods which makes international shipping of perishables possible. Additionally, control over humidity and air quality further enhances product protection.
What Types of Products Require Reefers?
Many products need specialised transportation. Products like frozen meats, dairy products, and pharmaceuticals are common. Flowers and certain chemicals also benefit from reefers.
It's not limited to food and drugs. Certain electronic components require a controlled atmosphere. These diverse applications make reefers indispensable in many industries.
What Are the Challenges of Using Reefers?
While very useful, reefers have some disadvantages, and the most important is that they are quite expensive to operate because they require a constant power supply besides routine maintenance. It is very crucial in this regard that the refrigeration units of reefers work effectively during shipment because failure can be quite costly with spoiled cargo.
Another challenge is the availability of reefers in some regions. The demand often outstrips supply, especially in peak seasons. Logistic managers have to make careful plans and coordination to get these specialised containers to meet shipping deadlines. Despite these challenges, their benefits in maintaining product integrity outweigh the difficulties.
How Are Reefers Impacting Sustainability in Freight?
Reefers are now also being designed with sustainability in mind. Newer reefers have energy-efficient refrigeration systems that minimise power consumption, reducing their impact on the environment.
