Cold chain delivery management
Cold chain logistics require a very high level of organization and tracking to ensure the chain is not broken at any point and teams can prove this.
Cold chain logistics involves low temperature supply chain made up of refrigerated vehicles, warehouses and distribution methods. It is critical that a cold chain is unbroken during the distribution process as even a temporary break in the temperature control can be devastating to the product. This process has been in the news recently with vaccines for Covid requiring to be delivered by cold chain. However, cold chain is common in food distribution, pharmaceutical and chemical industries and even grocery delivery. In fact, it has been available ever since refrigeration has been commercially possible.
For companies involved in cold chain operations planning needs to be rigorous. Speed of distribution is key in helping to avoid breaks and minimize the high costs associated with keeping temperatures controlled.

What is cold chain logistics?
Cold chain logistics involves the transportation and distribution of temperature-sensitive products. It is frequently used in the food, produce, health care, and pharmaceutical industries to transport perishable products that require temperature controls in storage and transit.
For example, meat products like chicken and fish have to be stored at sub-zero temperatures to prevent spoilage from harmful bacteria. Cold chain logistics preserves the integrity of shipments like meats and vegetables that require specific temperatures in their supply chains.
In 2011 Ewan McGregor worked with Unicef to raise awareness of cold chain issues in getting vaccines to children in remote regions of the world like Nepal. His documentary showed the precarious nature of trying to maintain valuable medicines at constant low temperatures in regions where distribution could only be achieved by foot or rudimentary forms of transport. In modern economies cold chain is made up of unbroken links between refrigerated distribution warehouses, vehicles and end consumers who have refrigerated means to receive consignments. This has been most apparent in the stories around Covid vaccine distribution recently.
However, all manner of products require cold chain systems such as foodstuffs and chemicals. If you ever see vehicles with the spinning air conditioning units mounted on their roofs then you are likely looking at a cold chain distribution vehicle.
What are the elements of a cold chain delivery system?
Packaging that is suitable for cold chain such as vacuum packs, perforated boxes, air conditioned shipping containers, blast freezer warehouses and trucks and vans with air conditioning built-in.
All of these elements need to be tightly controlled as even a small increase in temperature can result in massively increased degradation timelines for the products being shipped. Sensors systems and monitors that can help with reporting and alerting to problems are critical.
As a cold chain provider you need to know exactly what temperature is optimum for your product, what hardware you will need to get it from A to B safely, and how can you say with certainty that what you have done is correct, i.e. do you have monitoring at all stages of the process.
Challenges of cold chain logistics
- Cost of implementing total cold chain accuracy and monitoring
- Airflow management in transit vehicles can be difficult with loads needing to be evenly distributed in vehicles to allow air to travel throughout.
- Breaks in the process can occur easily as a result of power failures, human error and particularly in moving from one holding area to another, for example, from warehouse to vehicle.
- De-vanning and cross-docking protocols to be implemented successfully every time a van is unloaded or you need to move product from one vehicle to another.
- Reporting on integrity of logistics operations and proving that cold chain was maintained throughout involves expensive monitoring hardware and software reporting tools.
How to deliver successfully in cold chain with SmartRoutes
Set up priorities
In the SmartRoutes platform you can set up custom fields to nominate any variable involved in a delivery. You can also set up priority customers, products or stops that need to prioritized for delivery. This can be valuable in cold chain operations that are mixed with less perishable or sensitive materials. Complete the most important deliveries first to ensure they are completed successfully and without damage to the product. Allied to this, you might want to set up contactless delivery for some of your customers depending on Covid circumstances.
Set skills of delivery teams
Your delivery drivers may have certain skills that are necessary for a delivery. Perhaps they have cold chain accreditation, or they have experience in handling sensitive deliveries. Setting skills for drivers allows the SmartRoutes algorithm to match the right drivers with the right skills to the right delivery.

Save time and money in delivery management. Cut carbon emissions. Get oversight on your fleet. Impress your customers with superb communication tools.
Ensure you match the vehicles to the consignment
Not all of your vehicles might be suitable for all your consignments. They might to be a certain size, have a specific type of air conditioning unit, or have certain monitoring hardware installed in order to complete the cold chain delivery effectively. You can set up territories with certain vehicles assigned to that territory so the correct vehicle is paired with the right consignment.
Maintain a vehicle inspection roster
The most common way for cold chain deliveries to fail is a failure of the delivery vehicle. Unlike blast freezer warehouses which are static and well serviced with back-up plans in case of emergency, vehicles are far more precarious by their nature. Vehicle breakdowns, crashes, and even traffic delays can be enough to result in consignments perishing or the refrigeration units stopping working. If you have a regular inspection of your fleet and a pre-delivery inspection then you can avoid some of these simple but critical failures when out on the road.
Have a cold chain delivery checklist
A delivery checklist can help you to stay focused on the things that need to be done to ensure the vehicle and consignment arrives safely and on-time ETA. We have created a handy resource for you to copy or download. Cold chain delivery checklist.
Ensure consignments are correctly loaded to ensure airflow and ease of access based on stops order
Using SmartRoutes can help your dispatch and warehousing team to understand the vehicles available to them on a given day and at a given time. They must ensure that the vehicle is correctly loaded to allow airflow around the consignment and avoid hot spots in the cargo section. Loading should also be done taking into account the order of stops so drivers do not have to spend unnecessary time searching for the delivery package when at their destination.
Seal vehicles until delivery
All vehicles, once loaded, should be closed and sealed ready for departure. They should not be opened or left open during the loading phase. With SmartRoutes you can automatically create order loads for a vehicle from your existing database or your online ordering system. We can integrate this information with the SmartRoutes platform to automatically create an order list, assign it to a driver, and allow your warehouse or picking team to have the order ready to go when the vehicle arrives for loading. This level of organization has a knock-on effect at the depot by minimizing the time spent loading and discussing the days operations. It is all pre-organized and efficient. Drivers leave faster and deliveries are made more efficiently.
The SmartRoutes API can integrate with any system and connect in the relevant information to assist with deliveries. Your cold chain delivery will have other systems that should tie in with SmartRoutes to optimize your delivery routing and ensuring better efficiency in real-world conditions on the road.
A cold chain is dependent on the moving vehicles in the real world but no cold chain distribution manager or fleet manager should be without GPS fleet tracking on all their vehicles. With SmartRoutes mobile app you can see where vehicles are at all times and if they have diverged from the optimal route assigned to them. This level of oversight is essential to ensure successful deliveries and reporting on operations.
Live consignment tracker
Whether you are delivering produce to a retailer, medicines to a hospital or anything else in cold chain, you can be sure the end recipient, your customer will want to know exactly where it is on its journey. Using SmartRoutes' live package tracker your customers can locate on a live-map where their vehicle is and see it moving in real-time. This gives them peace of mind and you don't have to update them on progress by other means. It also cuts out missed deliveries or customers not being ready to receive their consignments. This can all be done with your own branding on the live tracker for a great delivery experience.
