NTC in figures

NTC was founded by Klaus Clasen in Ahrensburg by Hamburg in 1996, under the original name of Notstromtechnik-Clasen GmbH. The dynamic entrepreneur built up his firm with great skill and enthusiasm, not to mention rolled-up sleeves, and has continued to advance it ever since. His commitment, drive and know-how in turning technical problems into implementable projects was much appreciated by customers and employees alike. Right from the start. 

The Henkelhausen Group, to which NTC has belonged since then, was equally impressed in 2018. The Henkelhausen Group has been offering complete solutions in the field of motors and electrical engineering for years and is rounding off its extensive portfolio with NTC.

Another milestone was reached at the end of 2019/beginning of 2020: Klaus Clasen passed the baton to Jörg Böhme as the new Managing Director. As a trained and qualified electrician, he knows the industry from the ground up. With his move to the management of NTC, it is therefore also Jörg Böhme's declared goal to continue and further expand the outstanding NTC values - manufacturer independence, holistic approach and professionalism - in the long term.

We safely equip companies with emergency power so that they can operate independently and without worries!

This is the guiding principle of Notstromtechnik-Clasen.
Because: If a company's power fails, operations are immediately paralysed. This results in financial losses and, in the worst case, human lives are at risk.

Our mission is therefore clear: at NTC, we develop, install and maintain emergency power supplies that protect companies against these risks.  In this way, we create the basis for every company to be able to work without interruption and continue to grow.
To ensure that the NTC mission statement continues to grow, we have defined three (daily) core tasks and key NTC characteristics that clearly define how we work together internally and externally. These ‘values and behaviours’ have been communicated intensively to all new and old NTC employees in recent months via mailings, visualisations and consistent thematisation. That's safer! Because only if the common direction is right will everyone have the same goal: highly available, independent and energy-efficient emergency power technology as security in uncertain times. For everyone.

Together for our customers

We now have more than 90 staff working on the premises and in the field, ensuring that all our projects run as smoothly as possible. You will find them at our head office in Ahrensburg as well as in our branch offices in Frankfurt and Hannover. You will also find them at our service points in Bavaria, North Rhine-Westphalia and Berlin. As a result, our customer list reads like a who’s who of German data centres, telecommunications suppliers, and industrial, scientific & administrative names.

Of course we are very glad that we are meanwhile one of the leading suppliers in the country for high-availability, uninterruptible, energy-efficient emergency power supplies. But what is more important to us is that we continue to be able to satisfy our customers in Germany, Austria and Switzerland.

We offer complete solutions, create added value and take all eventualities into account. This is the only way we can realise a reliable, customised emergency power supply for each of our individual customers - from conception to implementation and monitoring of ongoing operations.

Our DEKRA Integrated Management System (IMS) guarantees that NTC complies with the strict quality and environmental guidelines as well as all occupational health and safety requirements above and beyond the call of duty.

It has been based on the following standards since 2024

ISO 9001:2015 | Quality
ISO 45001 | Occupational health and safety
ISO 14001 | Environment

It is a central principle of our work that we are be able to provide our customers with independence from the public mains supply and in this way to maximise their supply security. Which is why we are ourselves independent. We have taken the conscious decision to be able to choose freely from any equipment and component manufacturer anywhere in the world and to operate without exclusive contracts. This enables us to configure systems that can be systematically adapted to your needs and requirements in terms of their size, power output, cost, design and form. And we can do this without restricting ourselves to products from any particular supplier.
