Reefer Container: Cold Chain Logistics & GDP Temperature Control
A Reefer Container or Frigo Semi-Trailer is an insulated, thermally controlled transport unit equipped with an active refrigeration compressor. Capable of maintaining precise interior cargo temperatures from -25°C to +25°C, it is certified under the ATP Agreement and EU Good Distribution Practice (GDP).
Understanding Reefer: Comprehensive Technical Analysis
Operational mechanism and commercial application in international freight
Temperature-controlled logistics in Turkey relies on two main equipment types: 40ft High Cube Reefer ocean containers and multi-temperature articulated Frigo trailers (termo tır). Engineered with polyurethane insulation and high-performance refrigeration units (Thermo King, Carrier Transicold), reefer units continuously circulate conditioned air throughout the cargo hold via bottom T-bar floor grating. Certified under the ATP Agreement (Class FRC for deep freeze down to -20°C), modern units feature digital thermographs and dual telematics sensors transmitting real-time GPS coordinates, internal compartment temperatures, and door-opening alerts directly to dispatch operations.

Line-by-line allocation of operational duties, freight costs, and risk checkpoints
| Operational Phase | Seller Obligation | Buyer Obligation | Notes & Risk Handover |
|---|---|---|---|
| Pre-Cooling & Pre-Trip Inspection (PTI) | Carrier must pre-cool container to target temperature before loading | Confirms temperature setpoint on bill of lading | Valid PTI required. |
| Cargo Core Temperature at Loading | Shipper must bring cargo to target temperature prior to loading | None | Reefers maintain temperature; they do not cool warm cargo. |
| Continuous Temperature Datalogging | Carrier records digital thermograph logs throughout voyage | Inspects logs before signing delivery note | GDP compliance audit trail. |
| Genset Power Supply during Overland Rail/Truck | Carrier supplies clip-on or underslung diesel generator (Genset) | None | Maintains active power during transit. |
| Destination Temperature Verification | Hands over printed/digital temperature chart | Verifies core temperature of cargo during unloading | Immediate reservation if temperature deviated. |
Turkish Agricultural and Biopharmaceutical Cold Chains
Authoritative operational insights under Turkish Customs Law No. 4458 & border regimes
Turkey is a global agricultural powerhouse exporting fresh tomatoes, citrus, cherries, and figs from Antalya, Mersin, and Hatay, alongside biopharmaceuticals from Istanbul. Fresh fruit requires active ventilation settings (fresh air exchange in CFM or m³/h) to prevent ethylene gas buildup, while pharmaceutical products demand strict dual-setpoint (+2°C to +8°C and +15°C to +25°C) validation with calibrated sensors complying with EU GDP Directive 2013/C 343/01.
Key Turkish Export Compliance Points
- •ATP certificate (Accord relatif aux transports internationaux de denrées périssables) must be displayed on the vehicle chassis.
- •Ocean reefers require terminal plug-in power and monitoring at Ambarlı and Mersin ports.
- •Dual-evaporator trailers allow frozen goods (-18°C) and chilled goods (+4°C) to be transported in separate compartments of the same vehicle.
Common Shipper Mistakes to Avoid
- ⚠️Loading warm cargo into a pre-cooled reefer: the refrigeration unit cannot rapidly cool down warm pallets, causing rapid spoilage.
- ⚠️Stowing cargo above the red maximum load ceiling line, blocking conditioned airflow and creating hot spots in the trailer nose.
- ⚠️Failure of ocean carriers to plug in reefer containers during port terminal dwell, leading to catastrophic temperature spikes.
Questions fréquemment posées for Reefer
Direct answers to high-intent questions on responsibilities, costs, and risk
Q1:What is the difference between a Reefer Container and a Frigo Trailer?
A Reefer Container is an ISO ocean container (usually 40ft High Cube) designed for ships and port cranes with electric power plug-in. A Frigo Trailer is a 13.6m road semi-trailer with its own independent diesel refrigeration engine.
Q2:What temperature ranges do refrigerated trailers support?
Modern frigo units support temperatures ranging from -25°C (deep frozen fish, meat, ice cream) up to +25°C (ambient pharmaceuticals and temperature-stabilized chemicals).
Q3:What is an ATP certificate in international refrigerated transport?
The ATP certificate is a mandatory international certificate proving that the refrigerated vehicle's insulation and cooling unit meet UN standards for transporting perishable food across borders.
