Radial fans for industrial use - 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.

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.

SEPA EUROPE, the experts for customized cooling solutions meets the highest expectations with its wide range of guards for axial fans. Modern high-performance fans operate at high speeds which increase the risk of injury. To enhance safety, SEPA EUROPE offers guards for axial fans in every required dimension. The well-designed guards of SEPA EUROPE are not only extremely stable but also improve the appearance of each fan. The high-quality surface (chrome-plated, powder-coated, zinc-plated or pure stainless steel V2A or V4A) stands for a longer service life and extensive protection against corrosion. We perfect the product with excellent finishing and a flawless surface without sharp edges. Additional advantage: The guards of SEPA EUROPE are aerodynamically optimized so that the fans can operate with optimum efficiency. A further advantage is the simple mounting by screwing to the fan.
