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

10.07.2019 - New super flat chip cooler: a smart combination of „Kühligel“® and micro fan

A smart combination of a „Kühligel“® and a micro fan for achieving optimum thermal management

The new super flat active chip cooler of the cooling specialist SEPA EUROPE is a convincing solution for applications in the embedded computing sector, in particular for single board computers. The HZ25B05 with its dimensions of 25x25x6.5 mm can be installed even in flat applications and ensures highly effective heat dissipation. The size of this super flat design is not its only advantage, but also its exceptionally low noise level.

The heat sink is made of high-purity aluminium and has low thermal resistance. The integrated micro fan is also equipped with a special, highly durable MagFix® sleeve bearing designed for operating temperatures of up to 80°C.

Particularly noteworthy is the fact that the micro fan which is operated with a voltage of 5VDC, has a power input of only 0.3 W and a life expectancy of 400000 hours. The fan can also be equipped, if necessary, with a tacho output for monitoring the function. Both and the fan and the heat sink are available separately.

The cooling experts at SEPA EUROPE gladly assist you in choosing the required design.

14.05.2019 - Microfans of radial construction for sensor technology

Radial fans by SEPA EUROPE for new areas of application

The significance of air quality measurements whether in industry, households or in vehicles is constantly increasing. Manufacturers therefore, should equip their applications with the optimal sensor fan and in this respect SEPA EUROPE is exactly the right partner!

SEPA EUROPE has complemented its range of microfans with the radial fan HY20A with the dimensions of 20 x 20 x 6.3 mm. The air intake of the radial fan which is on one side is 2 l/min and with a sound pressure level of 5dB(A) at a distance of 1m, it is virtually inaudible.

As is the case with all microfans, the HY20A is equipped with the reliable Magfix sleeve bearing and has a service life of 400 000 h (MTBF) or 50 000 h (L10) at 40°C. The tachometer output constantly monitors the speed at which the fan is running.

The HY20A is also an interesting solution for the cooling of hot spots in embedded applications. This compact blower ensures that optimal use is made of limited installation space.

12.04.2019 - The smallest electronically commutated AC fan sets new standards

Double the flow rate at half the regular power consumption

With the ball bearing mounted EC fan UFT60BBP and a dimension of merely 60x60x25mm SEPA EUROPE closes a gap in the AC range of fans. It replaces the old AC fan with its high power consumption and has many advantages compared to the old design.

The new EC fan surpasses its predecessors by far. With an edge length of only 60 mm it generates virtually double the airflow whilst simultaneously only consuming half as much power. Despite the mounting depth that has been reduced by 5 mm, the new EC fan provides three times as much pressure in the operating area compared to the standard AC model.  This is made possible by a modern motor concept and redesigned rotor blades: A highly efficient, electronically commutated DC motor replaces the squirrel cage rotors that have been used so far. The motor is operated with DC voltage that is provided by an integrated AC/DC converter.

The life expectancy (L10) is a major issue and is approx. 50.000 hours at 40°C. The operating temperature is in the wide range from -20 to 70°C.

The EC fan UFT60BBP is suitable for all power supplies worldwide. Its speed therefore does not depend on the supply voltage and frequency.

SEPA EUROPE offers EC fans with up to 75% reduced power consumption in the dimensions 60x60 mm up to 280 mm and thus enables the user to fulfil the directives of the European Parliament with a simple and affordable product. An additional advantage of this fan is its
contribution to reducing CO2 emissions.
