Who we are and what we stand for

KELLER MSR is a division of KELLER HCW GmbH with headquarters in the Westphalian city of Ibbenbüren-Laggenbeck. KELLER MSR again is divided into three core areas.

First, we have the division MSR IAS (Intelligent Automation Solutions), dealing with the automation of new and existing installations for the bulk materials handling industry, in particular grain mills, mixing plants and animal feed plants. Their range of services encompasses the entire plant design and control systems including control cabinets, visualisation and process control technology.

The second business unit is MSR ITS (Infrared Thermometer Solutions). On a worldwide scale, MSR ITS manufactures and sells pyrometers, infrared thermometers and systems solutions for non-contact temperature measurements for industrial applications within the range from -30 °C to 3,500 °C.

A third business unit was added in autumn 2016. On a national level, it sells high-end infrared cameras manufactured by Workswell under the label MSR ICS (Infrared Camera Solutions).


The origins of the company KELLER HCW go back to the end of the 19th century when the Laggenbeck machine operator Carl Keller (1847-1932) developed the finger car for brickworks. Further pioneering inventions of Carl Keller followed and laid the foundation for today’s globally acting company. The name KELLER is firmly established in the heavy clay industry and demonstrates innovation and quality. Today, KELLER HCW GmbH is a division of the French Groupe Legris Industries.

Founded in 1954, its sister firm KELLER Spezialtechnik developed and manufactured control and measuring technology for dryers and, in 1967, it acquired a majority of the shares of the Pyro-Werk in Hanover, a company that had been producing pyrometers for non-contact temperature measurements since 1925. The administrative departments and the workshop were transferred to Laggenbeck in 1971. In 1977, KELLER Spezialtechnik and Pyro-Werk first merged to KELLER Spezialtechnik-Pyro Werk GmbH and in 1990 it became the business unit MSR of the KELLER GmbH.

In addition to the systematic development and the worldwide sale of pyrometers, the business unit MSR also established its own automation department. The focus of this department lies on control system for grain mills and compound feed plants, but also on control systems for a large variety of other plants in the bulk materials industry.

Both in the units IAS (Intelligent Automation Solutions) and ITS (Intelligent Automation Solutions), KELLER MSR has meanwhile become a constantly growing global player.


Keeping our customers satisfied is our motivation. We have always been anxious to develop innovative solutions for a large scope of industrial areas and to fully exploit the very limits of physical feasibility. High-quality products and excellent service before, during and after handling an order are a matter of course, as we see our customers as our highest asset.

It is with good reason that we consider ourselves as the number one regarding precision, reliability and innovation. You are welcome to judge if we stand by these values.


We do not want to rest on our laurels. We are committed to employ our creativity, determination and spirit for the benefit of our company with its long history. It is important for us to have an ear on the ground, to recognise trends and to embrace them, thus creating an environment that will ensure our presence on the world market with safe and sustainable high-quality products and an outstanding customer service. Pursuing these priorities has given us a leading position in a competitive market and we are determined to maintain this position in the long run.

The finest asset, however, are our people, as we believe that they make all the difference. It is their dedication and their knowledge that make a good idea to a great business success.
“If you want to build a ship, don’t drum up people to collect wood
and don’t assign them tasks and work, but rather teach them
to long for the endless immensity of the sea."
