In addition to Schmitz and Krone, Kögel, Cimc, Samro, Lecinena and Kässbohrer are also known for their refrigerated trailers. Although all refrigeration trailer are the same at their core, there are different options available that enhance and distinguish them. Among these optional features are a handlebar/lift axle, tail lift, bi-temp/dual-temp and sliding walls. In addition, an ATP/FRC certificate may be important.
As the name implies, refrigerated/freezer semi-trailers keep their load cool or frozen. Dual-temp trailers can even freeze part of their load and cool the other. These semi-trailers are mainly used for transporting perishable products, such as food. These decay if they are not cooled and must therefore remain under a constant (low) temperature.
Each refrigerated/freezer semi-trailer is equipped with a cooling engine. It is responsible for cooling the load space. The current and target temperature can be read on its display. The best-known producers of cooling engines are Carrier and Thermoking. Most cooling systems are powered by diesel, although more and more hybrid or fully-electric cooling engines are entering the market to meet the rising emission standards in cities.
The price of a trailer is based on its age and its options such as a double evaporator or lift axle. At BAS World you can already purchase a refrigerated/freezer semi-trailer for around €8,000. New trailers start at €50,000.
