Best Practice

Organization of functional areas to achieve an optimal material flow.

At our location in the Haan Technology Park | NRW, we operate production facilities designed specifically to meet our needs based solely on the requirements of optimum material flow.


The characteristics of the site were not initially taken into account in the original design (ideal layout) - the production and associated service and logistics areas had been optimally positioned in terms of how they related to each other. In what ultimately became the final layout, we modified our concept to match the actual conditions of the site.

The result is that we now have a future-oriented plant that provides us with plenty of space to accommodate new ideas and expansion at a later date.

  • targeted, long-term planning
  • sustainable use of all resources 
  • use of the state-of-the-art machines and systems
  • use of an integrated ERP system
  • documentation of quality-related information in CAQ system
  • high availability and best service

Garden City

Bordered by the Rivers Düssel and Itter, the garden city of Haan, with just over 30,000 inhabitants, is located between the Rhine Valley and Bergisch Land. In addition to the excellent infrastructure, the garden city offers additional benefits, such as the extensive range of educational services. There are 15 nursery schools, five elementary schools as well as two high schools and a Waldorf school. An adult education center and vocational college complete the educational facilities.

In Haan and its immediate surroundings, you will encounter both untouched countryside and the hustle and bustle of a busy urban atmosphere. In the town center, for example, the nostalgic charm of the half-timbered houses blends in with the variety of shops and businesses typical of a modern urban environment and the wide range of outdoor activities available is combined with the extensive range of modern urban and at the same time outdoor leisure facilities from a golf course, riding center, tennis courts and sports fields to cycling and hiking trails such as the trails on the the Neanderlandsteig.
The major cities of Cologne and Düsseldorf can both be reached within just a few minutes.


Green Building

The headquarters of EDUARD KRONENBERG GmbH is impressive in terms of both the design and indoor environment: with aesthetic architecture and a future-oriented energy concept that combines highly efficient renewable energy systems.

The key elements are the ventilation system with heat recovery via a run around coil system (RAC system) and the air-water heat pump, which provides both cooling and heating.

Combined heat and power plant connected to an absorption chiller to cover the continuous cooling requirement and the base load of the heating demand. The energy source for the air-water heat pump is air from outside the building. In winter operation, heat given off by the exhaust air system and the compressed air systems are used, enabling the heat exchanger to improve its performance even further.

As a result of the forward-looking energy concept, the new building offers numerous ecological and economic benefits. "EK's corporate headquarters are an excellent example of how outstandingly economical, resource-efficient and visual appeal can work in harmony," emphasizes architect Jochen Siebel. 
EK provides the entire workforce with an optimally equipped and up-to-date workplace.


Open Spaces

The interior of our headquarters was designed as a harmonious addition to its architecture. Colors, shapes and design reflect the EK brand. Glass walls and partition screens create a completely new working environment due to the bright and light workspaces. The modern open-space concept also represents the company values: openness, team spirit, creativity and innovation.



Nature project

With the settlement of several bee colonies on the EK premises, in addition to the EK Green Building and participation in the climate protection project ÖKOPROFIT, we would like to set a further example: We have realized that the constant search for solutions that have as little impact on our environment as possible and the protection of species are inseparably linked.

Billions of years ago, the project of a global network of all natural processes was launched on our planet. As the inventor of globalization, nature itself is the most experienced and best teacher of ecologically sustainable management. A symbol for the big picture in our world is provided in the smallest of detail by bees. As industrious pollinators of plants, along with a multitude of other insects, they are a natural and irreplaceable part of the ecosystem, because they contribute to the well-being of the fauna and flora all over the world.

For these reasons, the recent increase in bee mortality is also a global issue. The destruction of bee colonies can be observed not only in Germany, but internationally. Scientific findings indicate that the causes are also man-made - through the establishment of monocultures and the use of pesticides in agriculture, as well as the increasing threat of climate change.

EDUARD KRONENBERG GmbH is committed to the responsible and sustainable use of the valuable resources that nature provides us with by supporting bees and preserving and caring for their natural habitat.

One thing is clear: as a family, we think long-term, manage our affairs in a sustainable manner, like to reinvent ourselves and are open to new ideas. And this sense of unity is a wonderful thing.
