Refrigerated semi-trailer is one of the types of heavy-duty trailers that are designed to transport goods that require special temperature conditions. Such cargoes include meat, seafood, alcoholic beverages (wine in particular), medicines, flowers and semi-finished products. Modern refrigerated semi-trailers are equipped with refrigeration units capable of cooling the cargo compartment to a temperature of minus 20-30 degrees. However, in general, for the transportation of the above goods, compliance with the regime from -18 to +12 degrees Celsius is required.
Refrigerated semi-trailers do not differ in principle from their home installations. The only difference is in the cooling area. In order to provide cold for all 33 pallets of cargo, a lot of power is required. That is why most of these installations have their own internal combustion engine, which,usually runs on diesel fuel. Refrigerated semi-trailers consume approximately 3-4 liters of diesel per hour. The fuel in them is poured into a separate tank located inside the refrigeration unit itself.
First, the "ref" captures air from the street, then it goes through several stages of cooling (refrigerated semi-trailers also have their own refrigerant) and enters through the fan blades inside. The principle of operation is similar to a car air conditioner, only the scale of their work is different.
It is worth noting that new refrigerated semi-trailers are marked with a special sticker that shows that the installation meets a particular standard. As a rule, the inscription is painted in green or blue and is placed at the top of the body wall on both sides. Now all European-made installations, including the Krone refrigerated semi-trailer, comply with the FRC standard. This suggests that the system is capable of transporting goods in temperatures ranging from minus 20 to plus 12 degrees Celsius.
In terms of design, today's refrigerated semi-trailers have an isothermal body, usually made of fiberglass panels. Previously, many manufacturers used steel sandwich panels (a prime example is the Czech "ALKA" and the 2-axle Soviet ODAZ).
The cargo compartment of many trailers is equipped with special hooks for transporting meat carcasses, as well as transverse bars for placing goods in 2 tiers. Some models are equipped with special partitions thatallow transporting two cargoes at the same time in different temperature conditions.
All European refrigerated semi-trailers are 13.6 meters long, which allows them to transport cargo with a volume of more than 86 cubic meters (as a rule, they can fit from 33 to 36 euro pallets).
At the moment, the cost of a new trailer with a refrigeration unit in Russia is about 3-3.5 million rubles. At the same time, the cost of tented analogs is 2 times lower. Even a German 86cc Schmitz costs no more than one and a half to two million rubles.
