Thanks to our strong network, we provide sustainable, innovative, and globally deployable concepts—precisely aligned with your specific requirements. Our regularly trained specialists ensure that you consistently benefit from the latest state-of-the-art knowledge.

We are at your service worldwide—in Germany, Switzerland, Austria, the Netherlands, Hungary, Slovenia, Cuba, Dubai, Denmark, at sea, and wherever you need us.

Expertise

We ensure the hygienic safety and efficiency of your water and ventilation systems—from drinking water tanks, filtration systems, wells, and heat exchangers to evaporative cooling systems, wet scrubbers, and cooling towers. We also carry out professional cleaning and disinfection on board ships, either during port calls or at sea. With our in-house developed cleaning agents, practice-oriented training programs, and expert consulting on hygiene regulations and Legionella prevention, we reliably support you in operation, maintenance, and regulatory compliance.

Water Utilities

As a specialized service provider, we carry out the cleaning and disinfection of your drinking water tanks, filtration systems, and wells. We ensure hygienic safety, monitor water quality, perform maintenance and repair measures, and support you in complying with statutory requirements as well as in documentation for internal audits and regulatory authorities.

Drinking Water Installations

We manage communication with authorities such as public health departments, provide consulting on Legionella prevention, conduct initial inspections of drinking water pipelines in new buildings in accordance with VDI 6023, and perform cleaning, descaling, and disinfection of drinking water installations.

Evaporative Cooling Systems, Wet Scrubbers, and Cooling Towers

We support the operation of your evaporative cooling systems (VDI 2047-2), wet scrubbers (VDI 3679), and cooling towers (42nd BImSchV), including cleaning and disinfection, internal inspections, operational logbooks, water testing, risk assessments, and the coordination of accredited sampling services.

Air Handling Systems

We reliably carry out initial and follow-up hygiene inspections, including sampling as well as cleaning and disinfection of your air handling systems. In this way, we ensure the hygienic safety of your indoor environments at all times.

Heat Exchangers

To optimize heat transfer efficiency and improve your carbon footprint, we clean heat exchangers using methods and products specifically tailored to your system, developed in our own production facilities. Cleaning is performed either on site at your premises or in our workshop—without the need for dismantling.

Products

We also offer our in-house developed cleaning agents for purchase. These products enable the effective removal of virtually all types of deposits from a wide range of surfaces. Upon request, we can even manufacture the products under your own private label.

Ships

Whether sailing yacht, container vessel, or luxury cruise liner—every drinking water installation is susceptible to germs and bacteria. Our trained personnel carry out professional cleaning and disinfection of your drinking water tanks and systems during port stays or at sea. Heat exchangers are also cleaned regularly in accordance with professional standards.

Training Programs

We offer comprehensive training programs for employees and operators covering all relevant topics—from VDI 6023 Category C and the 42nd Federal Immission Control Ordinance (42nd BImSchV) to staff training and safety briefings, as well as chlorine and chlorine dioxide applications.
Our portfolio also includes training in accordance with DIN 19606, DIN 19643, BGVA 1, BGV/GUV D5, GUV R108, and GBI 868, as well as hygiene measures and new methods in swimming pool operations. In addition, we provide information on swimming pool–related illnesses and their prevention.
