INREI – About the company
INREI GmbH was founded by my father, Erich Knippscheer, in 1967, which means that it’s now been in existence for over 50 years. Over this time, we have succeeded in establishing ourselves as a market leader in industrial cleaning, and thanks to our continuous pioneering work we have been able to meet the highest quality standards.
Whatever the circumstances were, we have managed to achieve great success, particularly in the field of turbine cleaning – the “premier league” of industrial cleaning.
Thanks to excellent cooperation with our customers, we have always been able to achieve outstanding cleaning results not only in Germany and Europe but also in crisis regions such as Iraq and Nigeria. None of that would have been possible without our colleagues receiving the appropriate training such as SCC and First Aid exams. To ensure the highest quality standards, the management of our family-owned company is also certified to DIN EN ISO 9001: 2015.
