Reliable transport refrigeration: Fans and drive technology for refrigerated trucks

When transporting sensitive and perishable goods, the required refrigeration temperature must be maintained throughout the entire transport journey. The cold chain must not be broken, which is why refrigeration units and cooling systems for trucks must, above all, operate reliably and avoid downtime wherever possible.

To support long-term operation, refrigeration technology for refrigerated and deep-freeze semi-trailers, vans and other mobile refrigeration solutions is designed for use under diverse operating conditions. This includes requirements regarding mechanical loads, environmental influences and corrosion protection. Furthermore, to provide the required cooling capacity during transport, systems are deployed that combine high performance with cost-effective energy usage.

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.

Safety and protection for cooling on the road

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.

Refrigeration systems for trucks, trailers and semi-trailers have to be able to withstand a lot on the road and especially during loading and unloading: In addition to weather influences such as snow, rain, heat, cold and UV radiation, the material is also exposed to vibrations, shocks and other stresses when driving and moving the transported goods. Added to this are the inherent movements of the fans and drives, which also place a strain on the material and the technology used.

Our fans are extremely sturdily manufactured and score with an innovative biomimetic blade design that ensures optimum airflow and best efficiencies while minimizing wear.

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.

We manufacture technology you can rely on

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.

Thanks to their controllable drives, the EC fans from ZIEHL-ABEGG enable demand-based control. In combination with matching control and regulation technology, they support compliance with the required temperature conditions and can thus contribute to fulfilling relevant transport, storage and hygiene requirements.

Furthermore, the systems are suitable for use in conventional cooling systems as well as in modern refrigeration plants. For example, they can be combined with solutions that use refrigerants such as CO₂ under the F-Gas Regulation.
