Cold Chain Supply

In Cold Chain Logistics, keeping the product (food or medicine) in the right temperature range is not sufficient. For the quality and safety of cold chain products such as food, pharmaceuticals, serum, vaccines, etc., the increases and decreases in temperatures should also be monitored and it should be ensured that the increases and decreases in temperature remain within the specified limits.

Even very small changes in temperatures significantly affect the shelf life and safety of the products.

For microbiological growth to start and the quality of food to decrease, deteriorate and carry the risk of food poisoning, exceeding the specified temperature limits by even a few degrees is more than enough, especially in foods cooled between 0 and +1 degrees. The loss of quality in food products is directly proportional to the storage temperature and the time spent above the specified temperature values and is also affected by the change in temperature value.

Quality and food safety in the Cold Chain can be ensured by cooling to the ideal storage temperature as soon as possible after harvest or production.

In Cold Chain Logistics, the highest risk for temperature changes occurs during the transfer of pharmaceuticals or food products from cold storage to transportation vehicles, or from cold storage to ship or airplane at a port or airport.

In order to reduce these risks, new technological solutions and indicator label systems are being used by manufacturers and transporters.

The Cold Chain starts at the moment of production for food or pharmaceutical products. If food or pharmaceuticals are produced, they are produced at the ideal temperature and immediately packaged and then taken to storage.

Food products collected from the field are quickly packaged and then refrigerated to bring them to the ideal storage temperature. Temperatures outside storage facilities can often range from -5 degrees to 50 degrees, depending on the season.

Soğuk Zincir gıda veya ilaç ürünleri için üretim anında başlar. Gıda ya da ilaç eğer üretiliyorsa, ideal sıcaklıkta üretilir ve hemen paketleme ve buradan da depoya alınır.


Food and pharmaceutical products shipped internationally are mostly transported by sea and air. Airport or port transfers are made by refrigerated trucks in order to maintain the ideal storage temperature. The cooling capacities of the trucks are designed for this purpose. During the transfer, the temperature outside can vary between -5 degrees and 50 degrees and the products can be exposed to direct sunlight during their transfer at the port or airport. Under the sun, the temperature can reach up to 80 degrees.

The solutions used to maintain the ideal temperature during sea or air transfer ensure the continuity of the Cold Chain. Products encounter similar conditions at their destination as at the point of shipment. During the transfer from the destination to the warehouse, the products are again guaranteed with state-of-the-art Cold Chain security systems solutions.








GDP compliant

Maintaining the quality and integrity of medicinal and biological products during transportation is crucial for pharmaceutical manufacturers and logistics providers for public health and patient safety.

As most medical and biological products require a temperature-controlled environment at every stage of production and distribution, controlling storage and transportation temperatures is vital to maintain the quality and efficacy of medicines.

We at Thermo King understand that when the quality of medical product shipments is compromised, the risk is much more than lost cargo - it can jeopardize the health and well-being of patients. TK PharmaSolutions, Thermo King's comprehensive and dedicated platform of expertise, addresses the precise needs of the pharmaceutical industry by providing application know-how and a wide range of services.

What are Good Distribution Practices (GDP) for pharmaceutical transportation?

The aim of Good Distribution Practices (GDP) principles is to ensure that the high product quality determined by good manufacturing practices is maintained throughout the distribution chain. This means that the means of transportation used to receive medicines (such as APIs) and medical ingredients extend from production to distributors and wholesalers. It must also ensure compliant delivery to hospitals and pharmacies.

Distributors are required to comply with European Union guidelines on good distribution practices for medicinal products for human use.


Here are some things to consider throughout cold chain logistics;

After production, the transport vehicle must be loaded with products at the required temperature.

The transportation vehicle must be suitable for cold chain logistics.

Products should be placed in appropriate warehouses from the transportation vehicle.

When necessary, they should be taken from the warehouse and loaded back onto the refrigerated transportation vehicle.

The transportation vehicle must deliver the products to the companies that will sell the product.

Ensure that the products are at the required temperature when transferring from the business to the consumer.

If the cold chain process is not well controlled, some problems may arise. Below you will see what mistakes can happen;

1. Products can spoil below -18 degrees.

2. Products should not be frozen and thawed repeatedly. Only the amount to be used is thawed.

3. If the products are not used after thawing, they are not frozen again.

4. The cold chain process must be controlled throughout the shipment and storage process. -18 degrees must be maintained at all times.

Thanks to cold chain logistics, products are delivered to the consumer without any problems. The most important step after the production of frozen products is shipment. You can benefit from Gökdenizler Group cold chain service to avoid problems during the shipment process.
