High-performance and durable electric drives and DC/DC converters for mobile applications

Solutions optimized for mobile machinery, functional vehicles and ships

Complete focus on the successful realization of your application

End-to-end support from concept, designs and commissioning to aftersales


Who we are

ARADEX has been a reliable and competent partner for over 30 years as a pioneer in high-performance drive technology. While the company’s roots are in industrial control and drive technology for production machines, the focus has changed to mobile drive technology since several years now.

ARADEX is part of the Chinese WEICHAI Group since the end of 2019 and strengthens the corporate group primarily in the area of new energies / electric drive solutions. Irrespective of this, our corporate culture is still primarily characterized by the company’s founders and now around 80 employees at our site in Lorch near Stuttgart.

Our services – an overview

ARADEX has focused on the electrification and hybridization of
commercial vehicles, construction machines and special ships. Our core competence lies in the development and production of converters (inverters), DC/DC converters and electric motors as well as holistic powertrain optimization. Our drive solutions are characterized in particular by perfect tuning, clever technology features and above-average efficiency. As part of a holistic drive train optimization, we can also arrange and optimally integrate other drive components such as batteries, fuel cells, gearboxes, etc. from our partner network.



What guides us

Our goal is to help you achieve your goals. To achieve this goal, we are constantly working to continuously improve our products and services. Challenge us with your application!

An important concern for us is to help drive the transition to new energy. Our technology supports the goal of reducing CO2 emissions and thus stopping dangerous global warming. ARADEX stands for an environmentally friendly technology standard and a healthy future!

Added values for you

In our understanding, electrical energy converters, such as inverters and DC/DC converters, are among the key components of electric or hybrid solutions of commercial vehicles and mobile working machines. Going beyond the pure basic functions and using the basic structure of FPGA and microcontroller, we use our inverters and DC/DC converters for additive “smart” functions. For example, with VirtualSensorTechnology we make every actuator its own sensor in high resolution. Thus, we offer you the tool to collect valuable data in your specific application and optionally even use it in a direct process optimization.

Our project teams look forward to implementing optimized functions for your application.



History of ARADEX

ARADEX was founded more than three decades ago. From then on, the company has gone through several important stages of development and has been able to set new best marks with the product developments again and again

The most important milestones in the history of ARADEX

Certifications as quality features

Providing high quality for our customers is a central claim of ARADEX. This quality claim includes the products and services as well as process flows within the entire value-added process. For this reason, ARADEX (or in some cases individual product types) has been tested by independent institutes and got various certifications. These certifications represent verifiable quality features for our customers as well as for the end customer.

DNV certification

DNV granted type approval for the guidelines and standards for ships, offshore applications and maritime high-speed and light vehicles. Approved products are approved for installation on all classed vessels.

Certified product types


ISO 9001:2015 certification

ZDH-ZERT GmbH, a certification partner for crafts and medium-sized businesses certifies that ARADEX's quality management complies with the requirements of the DIN EN ISO 9001:2015 standard.

AEO-F Certification

The AEO certificate is an international quality seal. Its aim is to safeguard the international supply chain from the manufacturer of a good to the end consumer against terrorist attacks. ARADEX meets the required security standards, which ensures the protection of the goods and is therefore considered particularly reliable and trustworthy.

ECE test label (KBA)

Components on motor vehicles that require approval are subject to mandatory marking. The test labels mean that the respective required tests and approvals have been successfully carried out on the marked components. The type approval is recognized by the states participating in the ECE procedure and their authorities.

For compliance with ECE 10R and ECE 85R, please refer to the product information.
