Design of industrial fans - Import export

In the fluid dynamics laboratory of our Wasserburg competence centre, we design new fan wheels and turbines and optimise existing systems for performance, energy efficiency and noise emissions. We also develop complete systems of wheels with power units. Our range of tests includes suction operation, pressure operation and also unpressurised measurements. Revolutions up to 40,000 r/min and diameters of up to 250mm are possible. In our prototype department, we are able to simulate or modify the environmental circumstances of the fan wheels or turbines, thus achieving optimal operational conditions. Furthermore, we carry out mould-flow analysis, use ANSYS from external partners for the flow simulation and establish the fault probability and fault effect with FPFEs. New: Development of blower systems and optimization of ventilation systems.

A mixed-flow fan combines the advantages of axial fans with the characteristics of radial fans. Simply described, it is an axial fan with a fan wheel in radial format. This provides a cost-effective design, in duct or box design, with a stable fan curve and relatively high pressure. Our many years of experience and large product range give our customers peace of mind. Development, design and manufacture of fans takes place with the highest precision and with the highest quality materials. The fans are usually supplied as a complete unit. Mixed-flow fans are usually used as ventilation fans. Typical applications are ventilation solutions in gyms, sports halls, warehouses, commercial kitchens, factories or airport terminals. Depending on requirements, the design of a mixed-flow fan can be completely adapted to the customer’s needs. With the right dimensioning and material selection, a mixed-flow fan will work problem-free for many years.

The wall fans we offer are direct-driven axial fans that are easily installed in walls or ceilings. The wall fans can be in 1-phase or 3-phase design. Our many years of experience and large product range give our customers peace of mind. Development, design and manufacture of fans takes place with the highest precision and with the highest quality materials The fans are usually supplied as a complete unit, but we can also offer new impellers for existing wall fans.

Radial fans or centrifugal fans are a type of fan that uses centrifugal force to create a pressure increase and a volume flow. This type consists of a fan wheel that rotates in a snail-shaped cover. The flow enters the fan through an inlet placed axially with the fan wheel shaft and motor, and is then thrown out radially with the help of the force from the fan wheel. Unlike axial fans, the motor is not in the volume flow of radial fans. To change the performance and characteristics of centrifugal fans, different designs are used on the fan wheel. The strength of the centrifugal fan is its versatility. A radial fan can be designed to transport a variety of volume flows at a wide range of pressures. At higher flows and relatively low pressures, an axial fan may be a better option. Centrifugal fans are available in single and double suction versions.

In tough applications such as e.g. high temperatures or movement of corrosive gases, it is not always possible to mount a motor in the volume flow. The solution for this is the so-called bifurcated fan which is an axial fan where the air flow is divided in a tunnel, which means that the motor is not in the volume stream. It is thereby protected from possible harmful particles or high temperatures. Our many years of experience and large product range give our customers peace of mind. Development, design and manufacture of fans takes place with the highest precision and with the highest quality materials. The fans are usually supplied as a complete unit.

A roof fan can be the same name referring to two different types of fans. On the one hand, it is the classic fan that is mounted indoors in homes and spins around to create an air flow in a room (these are also called HVLS fans (High-Volume Low-Speed)). And partly it is the type of fans that we work with – i.e. fans that are mounted outdoors on roofs belonging to e.g. apartment buildings, schools or industrial premises. A roof fan is a fan that is part of the ventilation system and has the task of extracting hot air, moisture and pollution from the indoor space and blowing them outside. The fans are usually designed to be robust and weather resistant as they are mounted on the roof. Of course, there are a variety of material designs adapted to the application needs.

Renewable energy sources are something that is becoming more relevant every day. Biogas is an alternative and here FläktComp Sweden can contribute with high-quality fans that ensure that the biogas is handled correctly. Biogas fans are a type of gas-tight radial fan, adapted for use in biogas environments where the demands on materials and performance are very high. The fans are usually delivered as a complete unit consisting of fan wheel, motor, cover and vibration feet. In order to choose the right biogas fan, one should start from operating data and process design, as well as whether there are any special requirements.

ATEX fans are fans that are installed in environments where there is a risk that an explosive atmosphere can form. Therefore, these fans need to be designed according to the ATEX directives. Depending on the classification of the environment, internal solutions inside the fan, such as e.g. spark protection in the fan cover or non-sparking materials. While in other cases, EX-rated motors are also required. Explosive gases require special fans. Our factories are certified according to ATEX for the manufacture of fans for Zone 1 and 2 as well as for Zone 21 and 22 containing dust. The design, production and use of fans for explosive media or environment is clearly specified in Europe by standardized directives. To choose the right ATEX fan, one should start from operating data and process design, as well as whether there are any special requirements.

Axial fans are a type of fan that creates airflow through a fan wheel that rotates around an axis and moves the air parallel to the axis. Axial fans can also be called propeller fans and are usually delivered as a complete unit consisting of fan wheel, motor and cover. Typically axial fans are direct driven with the impeller mounted on the motor shaft. There are also other designs such as e.g. belt-driven or with shaft bearing and coupling. The axial fan’s strength is to transport large volume flows at low pressures. At higher pressures, a centrifugal fan may be a better choice. To reach higher pressures with axial fans, these can be connected in series. Usually, the efficiency of an axial fan is comparatively lower than that of a centrifugal fan. But by using guide rails, diffusers and other accessories, an axial fan can reach the same or higher efficiency. The flow of axial fans can be regulated with vane or damper or speed regulation.

manufacturer of all types of Axial fans

The fan and cooling specialist SEPA EUROPE unveils a true innovation this year: The RaAxial fan. This created term is a combination of the words radial and axial. The microfan with its dimensions of 17x17x4.5mm is ideal for compact, embedded applications and offers numerous possibilities, e.g. as an axial fan for the ventilation of housings or as a radial fan for blowing air onto the heat sink. A tailor-made „Kühligel®“ has already been developed for the latter which makes the cooling of hotspots child’s play when space is limited. Reliability has top priority at SEPA EUROPE. For this very reason the new fan is equipped with the tried and tested Magfix® bearing system. The life expectancy at 40 °C is 210 000 h (MTBF) or 40 000 h (L10).

As the need for fans that are used in applications subject to high temperatures is constantly on the increase, SEPA EUROPE is presenting its latest sleeve bearing fan equipped with MagFix technology that can be used for operating temperatures up to 85 °C. An added advantage is the extraordinary high life expectancy of 210.000 h (MTBF). This fan is not only available in the standard sizes but also as a tailor-made solution. With the high operating temperature of up to 85 °C, this innovative fan generation by SEPA EUROPE opens up a wide range of new applications for the user, not least the automotive sector. The term MagFix stands for magnetic fixation (positioning) of the fan propeller/rotor in sleeve bearing fans.

By mounting an axial fan, the effectiveness of the new Kühligel® can be increased considerably. Fanless solutions require a lot of space. They are heavy and expensive. For cooling with active coolers by SEPA EUROPE however, the new Kühligels are not only small and light but also extremely inexpensive. Thanks to intensive development work, SEPA EUROPE was able to construct a heat sink that enables fan mounting without extensive reworking using conventional screws. The choice of the suitable fan (size, sleeve or ball bearings, 5, 12, or 24 VDC, tacho, connector) enables the best possible combination that is required for the application in question. The fans used have a MTBF of up to 350000h (40°C) and thus meet the highest requirements. Thanks to its light weight, the Kühligel® can usually be mounted using double-sided adhesive heat conduction pads (TCTxx) or thermally conductive two-component adhesive (Hernon 746) which are both available from the SEPA EUROPE product range.

Thanks to the intelligent combination of DC fans with a fully integrated AC/DC converter, AC fans can now be operated at speeds that are independent of the power frequency. Up to 4500 rpm can be realized and the flow rate significantly increased if required. The EC generation in the dimensions 80mm to 280mm and with several different speeds replaces the previous AC fans in situtations where there is no DC voltage available and requires less power in the process. The previous AC fans can be replaced without restriction as the EC fans have identical dimensions and thickness. The versions that are smaller than 180mm have a wide-range input and can be connected without problem, worldwide to all AC voltage networks without need for further adaptation. This is underlined by the UL approval of the entire fan series.

The fan and cooling specialist SEPA EUROPE has now added three further models to its slimline radial fan series. The latest additions impress with their compact dimensions of 38 x 40 x 5 mm, 54 x 52 x 6 mm and 45 x 45 x 4 mm and have more than deserved the name „slimline“. All fans are equipped with the reliable Magfix sleeve bearings and have a service life of 210 000 h (MTBF) and 40 000 h /L10) at 40 °C. The PWM input in combination with the tacho output enables the speed to be controlled and monitored. It is not obvious at first glance, but the Model HY45AB05PNK00A tops with a pressure of 143 Pa. The new models will be included in the standard range and will therefore be available shortly from stock. SEPA EUROPE specializes in customized cooling solutions. Thanks to over 25 years of experience, SEPA EUROPE can offer you the appropriate solution for virtually every task.

Chip cooling with the aid of heat sinks usually requires a lot of space and is not only heavy but also expensive. The specialists at SEPA EUROPE have developed a chip cooler with minimum space requirements for compact designs. The core component of the compact cooler is the ultra-flat blower HY40H that is combined with a Kühligel® of pure aluminium. The special feature of the new cooling solution is its variability which means that the size and shape of the heat sink can be freely chosen. Users can thus assemble the cooler to optimally fulfil their requirements. With a thermal resistance of a mere 2.5 K/W, the new chip cooler withstands a power dissipation of up to 15 W and in doing so guarantees the operational safety of the entire embedded system. The blower is equipped with the highly durable Magfix® sleeve bearing and has an impressive service life expectancy of von 210 000 h (MTBF) at 40 °C.
