Reliable transport refrigeration: Fans and drive technology for refrigerated trucks
When transporting sensitive and perishable goods, the right refrigeration temperature must be reliably maintained throughout the entire route. The cold chain cannot be broken, which is why refrigeration units and systems for trucks must work reliably and perform without errors or failures.
To ensure error-free operation over long periods of time, the cooling technology for refrigerated and freezer trailers, vans and other mobile cooling solutions must be robustly manufactured and optimally protected against mechanical loads, environmental influences and corrosion. In addition, to be able to provide required cooling capacity during transport systems are required that are not only powerful and durable, but that also operate with maximum energy efficiency and therefore in an as economically, environmentally and climate-friendly way as possible.
ZIEHL-ABEGG manufactures and delivers highly efficient, robust and corrosion-proof fan systems for refrigerated trucks and mobile refrigerating systems. The drives in our biomimetic fans are compact, space-saving external rotor motors whose voltage and frequency can be precisely controlled. In this way, the system works according to demand at all times and only consumes as much energy as it needs to reliably keep the transported goods at the right temperature at all times.
Maximum efficiencies and the highest energy efficiency are achieved thanks to the perfect interaction of fans, motors and control modules. We manufacture all of these components ourselves and view them as a whole, right from the development stage, optimising their interaction until everything functions perfectly. Each individual product from ZIEHL-ABEGG is part of the Royal League for air, drive and control technology, and together they display their superiority to the full and impress with outstanding performance, consumption and acoustic values.
Many goods and products require refrigeration during transport, e.g. foods such as meat, fish, and dairy products, as well as medical or chemical products such as medicines, samples, or certain paints. But it is not only frozen and refrigerated products that need protection and must arrive at their destination safely and in perfect condition. The refrigeration units themselves and their technical components, which are used in harsh conditions, must also be well protected in order to function permanently and without faults.
The electric motors from ZIEHL-ABEGG are also designed for longevity and low maintenance thanks to robust materials, precise manufacturing and maximum running smoothness. The brushless design also means that there are no wearing parts at all, which is unavoidable with other designs.
Our customers can also choose the appropriate protection types for each specific application and place of use from our wide selection. We provide different designs of fans and drives, for example with blades made of the completely rust- and corrosion-free, high-performance composite material, ZAmid, which we developed in house. This synthetic material is as robust us steel, but completely resistant to moisture. We also provide insulated and gas-tight fans, as well as versions with special heat, cold and dust protection.
We can find the perfect solution for every area of application and every mobile refrigeration or air conditioning system that you and your customers will be completely satisfied with. With our worldwide sales and service network, we are also there for you wherever you are and can be on site quickly at any time. We will be happy to answer your questions, solve problems or develop the best system together with you to implement your individual specifications and which works trouble-free and reliably even under the most demanding conditions. Simply contact us for personal advice and allow us to impress you with certified “Made by ZIEHL-ABEGG” quality in the field of refrigerated and temperature-controlled trailers.
In the case of transport refrigeration, it is not only the reliable availability of the refrigeration system that is decisive, but also the ability to control the mobile refrigeration or air conditioning system as precisely as possible. In refrigeration logistics, everything depends on the right temperature, which in turn is determined by the goods to be transported. Frozen fish in particular should be transported at a constant temperature of at least -18°C in order to meet all food safety requirements. However, -14°C is sufficient as a safe transport temperature for frozen meat or frozen egg products. Fresh meat, sausages, and fresh fish and seafood require temperatures around the freezing point (maximum 2-3°C), while dairy products are safe to eat at 4°C. Flowers, fruit and vegetables do not necessarily have to be refrigerated but they will stay fresh for longer if transported at a temperature between 4 and 8°C.
In modern refrigerated trucks or freezer and refrigerated trailers, several separate refrigeration zones with different temperatures for different products can be set up simultaneously. It should be possible to set the refrigeration system precisely to the degree and provide the required transport refrigeration constantly at the set temperature. Using sensors and coordinated control technology, the system can quickly detect temperature fluctuations (which cannot be avoided, for example, during loading and unloading when the doors are opened) and compensate for these by adjusting the fan speed and output, for example. In the case of air conditioning systems, other parameters, such as the humidity content of the air, can also be measured and controlled as required.
EC fans from ZIEHL-ABEGG can be controlled incredibly precisely thanks to the modern, “intelligent” drives and together with the right control technology reliably provide the required temperature. This makes them an important component in ensuring compliance with all relevant transport, storage and hygiene conditions. What’s more, Royal League technology not only fits conventional refrigeration systems, but also harmonises perfectly with new, modern refrigeration systems that operate with environmentally friendly refrigerants such as CO2 within the framework of the F-Gas Regulation (Regulation (EU) No 517/2014 on fluorinated greenhouse gases).
