Refrigerated transport is the movement of temperature-sensitive goods, from fresh produce and frozen food to pharmaceuticals and chemicals, within a defined temperature range and an unbroken cold chain. Given Turkey's strength in agricultural and food exports, refrigerated transport is one of the most strategic segments of road logistics. Getting fresh fruit onto European shelves within days, delivering vaccines with their potency intact or keeping chocolate solid in July all depend on the right vehicle and careful operational planning. In this article Özd Global explains how refrigerated transport works, the vehicle types involved, the documents required and the factors that drive cost.
How Refrigerated Transport Works
A reefer vehicle consists of an insulated body and an independent cooling unit. The unit circulates air continuously inside the body to hold the set temperature. Modern vehicles carry data loggers that record readings throughout the journey, and those records can be handed to the consignee on delivery. Keeping the cold chain intact depends on pre-cooling before loading, minimising the time doors stay open and loading goods that are already at the correct temperature.
Which Goods Travel in Reefer Vehicles?
- Fresh fruit and vegetables
- Meat, poultry, fish and seafood
- Dairy products and eggs
- Frozen food and ice cream
- Chocolate, confectionery and bakery products
- Pharmaceuticals, vaccines and medical supplies
- Cosmetics and certain chemicals
- Cut flowers and nursery plants
Every product group has its own temperature and humidity requirement, so the owner of the goods should confirm storage conditions in writing before loading.
Temperature Ranges and Operating Modes
| Mode | Temperature range | Typical products |
|---|---|---|
| Deep frozen | -18°C and below | Frozen food, ice cream |
| Chilled | 0°C to +4°C | Meat, dairy, fish |
| Cool | +4°C to +12°C | Fruit, vegetables, flowers |
| Controlled ambient | +15°C to +25°C | Pharma, chocolate, cosmetics |
Some trailers are multi-temperature units with two or three separately controlled compartments, which improves vehicle utilisation on mixed food consignments.
Documents and Standards
For international refrigerated transport the vehicle is expected to hold an ATP certificate under the agreement on the international carriage of perishable foodstuffs, confirming that the insulation and cooling unit meet defined standards. Food shipments additionally require a health certificate, a certificate of origin and, where relevant, a phytosanitary certificate. Pharmaceutical movements may call for temperature records and validation in line with Good Distribution Practice. Complete documentation prevents the cargo from waiting at customs while the cold chain is at risk, which is exactly what our customs clearance service is designed to avoid.
Tip: Bring your goods down to the target temperature before the vehicle arrives. A reefer unit is built to maintain temperature, not to cool a warm load. Product loaded without pre-cooling can break the chain within the first hour.
What Drives the Cost of Refrigerated Transport
Reefer freight is priced above standard dry cargo for several reasons:
- Equipment cost: The cooling unit and insulated body represent a substantial investment.
- Fuel consumption: The cooling unit runs on its own engine and burns additional fuel.
- Season: Demand for reefer trailers peaks during the summer fruit and vegetable season, and rates rise with it.
- Temperature sensitivity: Deep-frozen or pharmaceutical loads with narrow tolerances need extra monitoring.
- Transit time: Cold chain loads are often moved with two drivers for speed, which adds to the cost.
Because rates move with route, season and market conditions, we recommend requesting a current quotation from our road freight team.
Common Mistakes and How to Avoid Them
The most frequent cold chain problems are overloading that blocks air circulation, doors left open too long and relying solely on the unit display for temperature monitoring. Leaving air channels between pallets, keeping the load below the ceiling line and using an independent data logger resolve most of these issues. The Özd Global operations team performs these checks at loading and briefs the driver with product-specific instructions.

Frequently Asked Questions
Can products with different temperature requirements travel together? In multi-temperature trailers, yes; each compartment is set independently. In a single-compartment vehicle all products must be compatible with the same temperature range.
Can I receive the temperature records on delivery? Yes. Data from the vehicle logger is reported at the end of the journey on request. For sensitive goods we also recommend placing an independent logger inside the load.
Why are reefer trailers hard to find in summer? During the fruit and vegetable export season demand exceeds supply, and availability drops. Planning your loadings at least a week ahead secures both a vehicle and a better rate.
