Reefer intermodal shipping is revolutionizing how temperature-sensitive goods move across long distances. As we enter 2025, businesses are turning to reefer intermodal solutions for their unmatched efficiency, reliability, and sustainability.
From pharmaceuticals to perishables, reefer intermodal shipping ensures products arrive fresh and safe. With advanced technology and better network integration, reefer intermodal options now offer more flexibility and cost savings than ever before. Let’s dive into the top 5 innovations in reefer intermodal shipping that are shaping the future of logistics in Canada and beyond.
What is a Reefer?
Think of a reefer container as a giant cooler on wheels! It’s a special shipping container that keeps things nice and cold inside, like a refrigerator. Reefers (sometimes called RF containers) can keep things frozen, chilled, or just cool, usually between -30°C and +30°C. This makes them perfect for transporting perishable items like frozen food, ice cream, and other items that need to stay cold.
How Does Reefer Intermodal Work?
Reefer containers operate on a closed-loop system, actively managing temperature to ensure the safe transport of perishable goods. This system continuously collects heat from the container’s interior, pumps it outwards, and dissipates it. This intricate process allows the reefer to maintain a constant, desired temperature for extended periods. Imagine transporting ice cream – the reefer unit will tirelessly work to maintain a frigid -40°F environment until the ice cream reaches its destination. This technology, known as cold chain logistics, forms the backbone of safe and reliable transportation for temperature-sensitive products.
Reefer units achieve cooling primarily through two methods:
- Cryogenic Cooling
This method utilizes the natural cooling effect of carbon dioxide as it transitions from a solid to a gas state. Essentially, frozen carbon dioxide “ice” melts within the system, absorbing heat from the container’s interior.
- Diesel-Powered Generators
These generators provide the power needed to operate the reefer unit’s cooling system, ensuring chilled conditions for the cargo throughout its journey.
Reefer Components
Unlike your standard trailer, a reefer is a high-tech cooler on wheels, packed with extra parts to keep things nice and cold inside. Here’s a breakdown of what makes a reefer work:
- The Mighty Reefer Unit
This is the heart of the whole operation. It’s like a mini air conditioner that keeps the inside cool.
- Air Chute
Imagine a giant funnel! This helps direct cool air throughout the container.
- Insulated Box
This acts like the thick walls of your cooler, keeping the cold air in and the hot air out.
- Heavy Duty Tires
Just like any big rig, reefers need strong tires to handle the weight and different road conditions.
- Smooth Ride Suspension
This fancy system helps keep the ride smooth, protecting the cargo and the reefer unit itself.
- Dedicated fuel Tank
Reefers have their own dedicated fuel tank, separate from the truck’s fuel. This special tank can hold up to 50 gallons, and the best part? How the truck is driven doesn’t affect how much fuel the reefer uses.
Now, let’s get into the science behind keeping things cold! Reefers use a closed system with these key players:
- The Compressor
This acts like a tiny pump, sucking in warm air and squeezing it tight, turning it into hot liquid.
- The Condenser
This is like a radiator. It takes the hot liquid from the compressor and cools it down using outside air, releasing the heat.
- The Evaporator
This is the real chiller! It takes the cooled liquid and turns it back into gas. In this process, it absorbs heat from the air inside the container, making it nice and cold. The cool air then blows throughout the trailer, and the cycle starts all over again!
By working together, these parts ensure your favorite frozen treats, fresh fruits, and other temperature-sensitive goodies arrive perfectly chilled at their destination.
Why Use Reefer Intermodal?
Unlike other standard shipping containers, reefer containers ensure a wide variety of temperature-sensitive goods arrive at their destination fresh, delicious, and ready to use.
Here’s a glimpse of what you might find traveling inside a reefer:
- Perishable delights
This includes all your favorites – fresh fruits and vegetables, dairy products, and delicious meats.
- Beverages you love
From refreshing sodas to your morning coffee, some beverages also require a cool journey.
- Life-saving medications
Certain pharmaceuticals need precise temperature control to maintain their effectiveness.
- Baked goods on the move
Frozen pastries and other treats often travel in reefers to stay fresh for longer.
Using reefer containers is crucial for several reasons:
- Protecting from Freeze
Some products are sensitive to freezing temperatures and need a cool, but not freezing, environment.
- Maintaining Stability
For items that require consistent temperature control, reefers ensure they stay perfectly chilled throughout their journey.
- Keeping You Informed
Modern reefers are equipped with state-of-the-art technology:
- Control Units
These allow for remote monitoring and adjustment of the temperature inside the trailer.
- Temperature Sensors
These provide real-time data on the temperature conditions within the container.
- GPS Tracking
You can track your shipment’s location and ensure it arrives on time and at the optimal temperature.
By utilizing reefers and their advanced features, businesses can guarantee their temperature-sensitive goods reach their destination in pristine condition, preventing spoilage and safeguarding valuable revenue.

Drivers Guide for Handling Intermodal Reefer’s
There are two key parts of operating Reefer Intermodal freights, they are –
Picking Up Intermodal Reefer
When a driver is tasked with a “live intermodal reefer pickup”. That is mainly collecting a reefer container from the rail yard. Some of the steps crucial for this smooth operation are:
- Fuel Up
The driver should ensure the reefer unit’s fuel tank is filled, guaranteeing uninterrupted operation during transport.
- Temperature Verification
The container’s temperature setting must be meticulously checked and adjusted to precisely match the specific needs of the cargo.
- Alarm System Check
Prior to departure, a thorough inspection of the reefer’s alarm system is vital to identify any potential issues before they escalate.
Delivery of Intermodal Reefer
For deliveries involving a loaded reefer intermodal container originating from the rail yard, the driver’s focus shifts to ensuring the cargo reaches its destination in optimal condition.
- Fuel Gauge Monitoring
Due to the uncertainty of remaining fuel in the generator (genset), the driver must meticulously check the fuel gauge upon receiving the container.
- Fueling for Delivery
If the fuel level is insufficient, it’s imperative to refuel the genset before proceeding. This ensures the temperature remains consistent throughout the delivery process.
- Fuel Reimbursement
Carriers can claim reimbursement for fuel costs by including them as an “accessorial charge” associated with the trip.
Conclusion
The future of logistics is being reshaped by the cutting-edge developments in reefer intermodal transportation. As businesses prioritize freshness, reliability, and environmental responsibility, reefer intermodal continues to prove its value.
Whether you’re shipping coast-to-coast or across borders, embracing reefer intermodal solutions can drastically reduce spoilage, streamline operations, and cut emissions. Staying informed about the latest in reefer intermodal shipping gives your business a strategic edge in 2025 and beyond.
