Waesseri GmbH becomes PPCHEM AG

As of January 1st, 2019, the publishing house Waesseri GmbH was transformed into the new company PPCHEM AG.

Business Areas


The PowerPlant Chemistry® journal has been publishing for more than 19 years, with its 20th anniversary coming up. This milestone will be celebrated with the July/August 2019 journal issue. PPCHEM AG will continue publishing the journal in the same well-established manner and present publishing policy as before. The journal will also continue to publish an interesting mix of scientific peer-reviewed papers and technical reports from the power industry, all of them relating to the topics of water treatment, cycle chemistry in power and industrial plants.

Conferences & Seminars

PPCHEM AG will continue to organize international conferences and forums as in the past years with over 30 events organized all over the world. PPCHEM AG will also introduce seminars and technical trainings for operators.
Further details will be published regularly and in due time – Stay tuned!

Consulting & Training

PPCHEM AG will also be offering technical consulting services related to water treatment, cycle chemistry in power and industrial plants of all types and sizes. During the design phase of a power plant, owner’s engineers and EPCs can obtain expert advice and support. Power plant operators can contract PPCHEM AG for site-specific support ranging from assessments, troubleshooting, to the optimisation of cycle chemistry regimes and the related trainings of operators.

With the reorganisation and the added expertise, PPCHEM AG repositions itself to better serve its customers, building on the legacy of Waesseri GmbH and its precursor organisation.
