Karl Kruse Mourns Company Founders

We sadly bid farewell to our father and company founder Karl Kruse, who died on 4 June 2019 at the age of 93 years.

When Karl founded Karl Kruse GmbH & Co KG in 1951, Karl Kruse was one of the pioneers of distribution. He started buying up overstocks of the radio and television industry. At the same time, he imported goods from the Far East and the USA and informed his customers about current products with his “yellow lists”.

Through entrepreneurial courage and tireless commitment, he built up the company and successfully managed the business for many years until the handover to us. In spite of constantly changing market conditions, he recognized opportunities early on and helped his customers develop them profitably. Together with his employees and customers, he developed the right strategy, always keeping an eye on the risks. Mutual trust formed the basis for mutual success.

The elemental building blocks of Karl Kruse’s success are the consistency, trust, quality, motivation and commitment of his employees for each individual project.

For us his death is a great personal loss and we will miss his joie de vivre and warmheartedness very much. The many eventful and shared years under his management and the years thereafter as a caring partner will always remain in honorable memory. We will continue to live the corporate culture he has shaped and are very grateful to him.

We miss you, think of the beautiful memories with you and wish you a good journey wherever you go.
Klaus and Alexander Kruse

What Technology Is The Biggest Challenge For Cooling And Thermal Management?

Higher system clock rates and a higher packing density place considerable demands on effective and cost-efficient cooling and heat management. This trend in fact has led developers to add fans to systems that already use passive cooling technologies, such as heatsinks and heat spreaders.

Fans offer the solution to increase heat dissipation in smaller system packages, but can also burden the developer with problems such as mechanical stress, fan failures, increased acoustic noise, and increased fan power consumption. Since the system relies on heat removal by the fan, it is important that the cooling solution has an error detection mechanism.

System designers who are not concerned with the management of the fans in the system are subject to increased costs due to increased downtime and field replacement. The customer’s perception of the overall system quality and reliability of the equipment is also compromised.

AC fans, DC fans and blowers are now available with features that solve the problems of noise, reliability and power consumption. Fan features such as intelligent temperature controls can reduce power consumption by up to 30% while reducing noise. Air flow monitors and rotor blocking alarms sound when the fans are not performing optimally to ensure a reliable cooling solution that meets nearly all application requirements.

Orion Fans designs and manufactures a wide range of AC fans, DC fans, EC fans, harsh ambient fans, fan shafts, fan accessories, motorized impellers and blowers. The facility will accelerate the development of new products that meet specific customer needs in a variety of applications. Combining a wide selection of fans and fan accessories with unsurpassed customer service, Orion fans appeal to engineers and buyers by developing and delivering innovative cooling solutions.

Alternative Super Junction Power MOSFETs For Power Electronics Design

Super Junction MOSFETs (SJ-MOSFETs) are high-performance MOSFETs designed for higher power and voltage switching and used in voltage converters.

In contrast to conventional MOSFETs, SJ MOSFETs have a much larger pn junction between source and drain. This leads to an extremely low contact resistance between said electrodes. This is in the switched state (on) at about 0.1 ohms. This low on resistance causes low heat development due to the power loss.

Karl Kruse, a global distributor of electronic components, and CYG Wayon, is one of global core providers of electronic circuit protection solutions, announced a cooperation agreement.
