We are…

sustainable:

As a world market and technology leader, we produce machines for conveying, heat treatment, cooling and dosing of bulk materials as well as for shutting off process areas. Due to our extremely high level of vertical manufacturing and quality management  as well as our conservative design our machines stand out with a long service life. We ensure with our full service offers the maintenance of the plants and guarantee the delivery of spare parts even after years. Due to the excellent reparability of our machines, we avoid a resource-intensive new production of the entire machine.

specialized:

Together with our highly qualified engineers and technicians, we develop and manufacture individual machines, precisely adapted to the needs of our customers and the field of application. By means of computer-aided engineering (CAD), we check the correspondingly required product characteristics in simulations and carry out tests in our test centre. Through this process of development, we are offering the best, tried and tested solution for the application to our customers.

certified:

The confidence of our customers in our quality and safety is our obligation: Our engineers and technicians in the fields of plant planning, engineering, project management, construction, production and service guarantee the highest quality standards. KÖLLEMANN is certified by TÜV Rheinland according to ISO 9001:2015 and AD 2000 regulations/DIN EN ISO 3834. The performance of our quality management system is regularly audited by independent certification bodies.

international:

KÖLLEMANN systems and machines are used worldwide. For our customers in more than 80 countries our our engineers and service technicians rise each day to deliver the best and innovative service to them. We are proud that our machines are in operation worldwide in the sections of raw materials, chemical and cement industries as well as the energy and power plant technology, environmental and recycling sectors. Being available to our customers worldwide through our local KÖLLEMANN representatives and partners is our valuable asset to guarantee the best possible service and short communication paths.
