Water – The market of the future.

Taking responsibility for a valuable resource.

Water is used in the greatest variety of ways – as widespread as it is, that is how many applications there are. Our customers, too, have the widest range of requirements for water quality and for the measurement technology designed to ensure that quality. For this reason, we offer you individualized consulting, with the goal of always making the best possible selection of measurement technology.

If customer-specific solutions make sense, we are able to develop them in consultation with you. Furthermore, we provide services such as system commissioning and maintenance contracts – anytime and anyplace.

Water treatment and monitoring – robustness and high availability.

In many industrial processes, reliable water treatment makes an essential contribution to product quality, and also improves system safety and efficiency. Contamination of water circulation systems can cause great damage and must be detected early through continuous monitoring of the relevant quality parameters.

In circulating steam or cooling systems, this monitoring avoids damaging deposits which would lead to corrosion or local overheating. In addition, it is possible to immediately react to any leaks in the process. The monitoring of filtration stages ensures the long-term high quality of feed water. For these purposes, KROHNE offers a broad range of analytical measurement technologies.
