From fruit, vegetables, meat, and fish to ready-to-eat convenience products - supermarkets offer fresh goods for sale every day in their refrigerated counters, refrigerators, and freezers. In order to guarantee that products are stored at the right temperature to keep them protected, these refrigeration units require a continuous power supply day and night, whether the supermarket is open or closed.
The number of these continuous power consumers at a single supermarket quickly adds up: besides refrigerated and freezer counters, they can also include convenience units for product presentation, refrigerated cabinets and freezer chests for chilled drinks, fresh goods, and dairy products, promotional units for special offers, and ice chests or drinks units in the checkout or service area.
For this reason, energy-efficient devices are in high demand - they require as little energy as possible to keep products cold, while also operating as quietly as possible. After all, customers at supermarkets want to shop in a relaxing environment that doesn't disturb them with loud fan noises each time they open a refrigerator cabinet or freezer chest to choose an item.
ZIEHL-ABEGG offers pioneering solutions that enable supermarket operators to achieve long-term reductions not only in their energy costs but also in noise emission: by combining low-noise FE2owlet fans with the latest motor technology. After all, efficiency is of paramount importance for all fans throughout the refrigeration chain. Shaded pole motors, which were once a popular choice for cold storerooms, had an extremely low efficiency rating of only 18 percent, with more than 80 percent of the energy consumed by them escaping into the surrounding air as heat loss. As a result, fans needed even more power in order to cool the surrounding air to the required temperature. You can break this undesirable cycle of energy waste by using fan motors from ZIEHL-ABEGG. These quiet and strong motors achieve a very high efficiency rating, generating much less heat loss and cooling much more effectively using significantly less power.
In this way, products can help meet applicable statutory requirements as well as application-specific market demands.
Alongside energy-related requirements, the selection of suitable refrigerants also plays an important role. In many markets, refrigerants with a lower GWP (Global Warming Potential) value are increasingly being used. Regulatory frameworks arise, for example, from the F-Gas Regulation EU 517/2014 and other applicable regulations. In this context, refrigerants with diverse physical properties are increasingly employed, including flammable or combustible media. Depending on the application, this can result in additional requirements for motors and ventilation systems. These include, for instance, requirements in accordance with DIN EN 60335-2-40, DIN EN 60335-2-89 or designs with appropriate ATEX approval.
FE2owlet fans with EC055 are available in versions with corresponding approvals. Information on the respective application options and approvals can be found in the product-specific documentation.
The biomimetic blade design of our FE2owlet fans provides unique performance and excellent aerodynamic properties. This makes these fans not only exceptionally efficient, but also quieter than comparable conventional models. In developing them, our engineers were inspired by an example from nature: specifically, the owl. Owl wings served as a model for the design and optimization of the fan's blades, which, in combination with the latest motor technology, contribute numerous advantages:
