17.06.2020 - SEPA EUROPE extends its range of RaAxial fans

SEPA EUROPE extends its range of RaAxial fans

This new generation of fans is extremely economical and exceptionally quiet

Even the micro fan MF17B05 from the RaAxial range was a true innovation simply because it can be used not only as an axial fan but also as a radial fan. The micro fan has now a „big brother“– the LF40E05.

The LF40E05 provides numerous possibilities for embedded applications. It can be used
either as an axial fan with integrated finger guard or as a radial fan in combination with a heat sink. Together with a matching Kühligel® the flat cooling units have a height of approx. 12 mm. In other words, they are ideal for compact applications.

In order to achieve the optimum size and heat dissipation, customized dimensions and shapes can be realized. The new model with its 0.15 W power input during operation, is extremely economical with regard to its diverse application possibilities. And that’s not all, the new RaAxial fan has aerodynamically optimized blades that have a significant effect on the noise behaviour. The LF40E05 is thus exceptionally quiet.

Thanks to the tried and tested MagFix® system, the LF40E05 is a reliable fan with a service life of 400 000 h (MTBF).


03.04.2020 - SEPA EUROPE presents the latest 60 mm fan series

SEPA EUROPE presents the latest 60 mm fan series

Based on the axial fan series MFB60B that has been extremely successful for many years on the market, SEPA EUROPE is now presenting a powerful upgrade with its PLB60B series.

The fans of the PLB60B series, with the dimensions 60x60x15 mm have an optimized blade geometry that enables a maximum flow rate of 28 m³/h. The new SEPA fans set new standards in their class and are suitable for reliable CPU cooling in a broad range of applications.

The robust ball bearing system guarantees a long service life of 70.000 h L10 and 550.000 h MTBF at 40 °C and ensures a safe and smooth operation over many years.

The fail-safe axial fans are available in the operating voltages 5, 12 and 24.  A PWM input with which the speed can be adjusted according to requirements is an available option.


05.02.2020 - A more variable, smarter chip cooler on the basis of an ultra-flat radial fan

Product innovation - Embedded World Trade Fair 2020

SEPA EUROPE has developed a powerful active cooler specially for compact designs. It is as small as a matchbox and has a thermal resistance of a mere 2.5 K/W. The ultra-flat radial fan can be combined with varying heat sinks for customized solutions. The product innovation will be presented for the first time at the Embedded World Trade Fair 2020.

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. Thanks to the PWM input combined with the tacho output the speed can be both controlled and monitored.

The lightweight compact cooling unit is easy to attach using the double-sided adhesive thermal conductive foil TCT or the thermally conductive two-component adhesive HERNON 746. Both are available from SEPA EUROPE’s wide product range.

13.01.2020 - Complete assembly for powerful chip cooling

Chip cooler HXB40FGK

Inspired by customer inquiries, SEPA EUROPE has developed a new, modular assembly for the efficient cooling of chips. The core component is a SEPA axial fan that is mounted on a 40 mm pure aluminium heat sink – a so-called Kühligel®.  It is equipped with a finger guard and a double-sided adhesive heat pad for screwless mounting on the housing or inside the device.

Thanks to the compact design, the light weight and the screwless mounting, this assembly enables accurate positioning and thus effective cooling of the hot spot. The chip cooler HXB40FGK is equipped with a high precision ball bearing and can be used at ambient temperatures between -10 and +85 °C thus opening up a wide range of application possibilities. A further advantage is the long service life of the fan with 350 000 h (MTBF) at 40°C.

The chip cooler assembly HXB40FGK is supplied as a standard component. It can however, be customized. Parameters, e.g. size, tacho output, PWM input, operating voltage or connector assembly, can be specially tailored by SEPA EUROPE to meet the requirements of the customers.

11.10.2019 - 40 mm classic fan with optimized aerodynamics

New fan blades provide improved performance with the same level of noise

One of the most popular SEPA EUROPE fans is the axial fan with the dimensions 40x40x10 mm and the popular Magfix® sleeve bearing. This year it underwent complete revision and further development. The new fan generation is known as the LF40P and with the same external dimensions is installed in the same way as the previous model.

The new and currently unique rotor geometry is obvious at first sight. It is completely different from the previous shape and layout. Thanks to the distinctive rotor blade with a cut, either a clear noise reduction can be achieved at the same speed or the same noise level as previous generations with 25% more air performance. The current model is equipped with the SEPA MagFix® bearing and PWM input with which the speed can be set to meet the necessary requirements.

The LF40P is an excellent example for the permanent further development of products at SEPA EUROPE
