About us
INWATEC – Chemical water treatment with real-world expertise
INWATEC specializes in industrial water treatment for cooling systems, steam boilers, process water, and wastewater.
We develop and manufacture our own chemical products and combine them with measurement and control systems that transmit real-time data to our Inwanet platform, allowing you to monitor system condition and water quality from anywhere in the world.
This gives you insight into trends and deviations, enables settings to be automatically adjusted where necessary, and allows you to take informed action before problems lead to damage or downtime.
Our engineers are technical experts with years of practical experience.
We design treatment concepts that control scale, corrosion, and microbiological issues, and we tailor these concepts to your specific systems and business objectives in collaboration with you.
At the trade fair, we’ll demonstrate how you can make your current water treatment more sustainable, monitor it more effectively, and operate it at a lower total cost of ownership.
Products & services
INWATROL adplus
INWATROL adplus is a system for the automated generation and dosing of monochloramine in cooling water systems. The unit produces monochloramine on-site from two precursor chemicals and delivers the biocide directly into the water circuit according to system requirements. This approach eliminates the need to store large quantities of finished biocides and allows dosing rates to be adjusted to changing operating conditions. Monochloramine is used to control microbiological contamination in industrial water systems. It is effective against Legionella, Pseudomonas, slime-forming bacteria, sulfate-reducing bacteria, algae, yeasts, and fungi. In addition, monochloramine supports the reduction of biofilm formation and helps minimize the risk of microbiologically influenced corrosion within cooling water systems. The dosing process is fully automated and can be adapted to the specific requirements of the application. Both dosing quantities and dosing intervals can be configured and adjusted as needed. The system is suitable for a wide range of cooling water installations, including large-scale systems with varying water volumes and operating conditions. INWATROL adplus can be integrated into the INWAnet online monitoring platform, allowing operating and dosing data to be continuously recorded and accessed remotely. The system automatically generates alarm notifications if predefined limits are exceeded or if operational faults occur, enabling operators to respond quickly and take corrective action when necessary. As with all INWATROL systems, INWATROL adplus is designed and configured according to the specific requirements of each installation. System layout, dosing strategy, monitoring functions, and communication interfaces are tailored to local operating conditions, resulting in a solution that is adapted to the application rather than requiring the application to fit a predefined standard.
INWATROL expert
INWATROL expert is a modular monitoring, control, and automation system for cooling water and boiler water systems. Each installation is individually designed to meet the specific requirements of the application, enabling the continuous measurement and monitoring of water quality and operational parameters. Depending on the requirements, a wide range of measurement technologies can be integrated, including pH, conductivity, redox potential, turbidity, inhibitor concentrations, and other application-specific parameters. In boiler water systems, for example, dissolved oxygen measurement can be incorporated to continuously monitor water quality and detect conditions that may promote corrosion at an early stage. All measured values are continuously recorded and can be accessed and evaluated via the INWAnet online platform or existing process control systems. If measured values exceed or fall below predefined limits or target ranges, the system automatically generates alarm notifications. This enables operators to respond quickly to changing operating conditions and take corrective action when required. A key feature of INWATROL expert is its focus on customer-specific requirements. Rather than relying on fixed standard solutions, each system is individually planned and configured to suit the application and operating environment. Thanks to its modular design, INWATROL expert can be installed in both new and existing systems and can be expanded with additional measurement and control technologies as requirements evolve. The result is a solution tailored to the specific needs of the process, providing continuous monitoring and supporting the efficient control of water treatment programs.
INWATROL L.Nella+
INWATROL L.nella+ is a patented measuring device for the automated determination of Legionella concentrations in cooling water systems. The system is designed for continuous monitoring of hygienically relevant water quality parameters in evaporative cooling systems, cooling towers, and wet scrubbers. Connected directly to the water system, the device automatically collects and analyzes water samples and determines the concentration of Legionella spp. within approximately five hours. Measurement results are displayed online via the INWAnet platform in CFU/100 ml, providing operators with continuous access to current hygiene data and trend analyses. The measurement method is based on a patented process that determines the metabolic activity of living Legionella cells and shows a high correlation with established cultivation methods according to ISO 11731. In addition to Legionella monitoring, the system can continuously measure and document key cooling water parameters such as chlorine, redox potential, conductivity, and pH value. INWATROL L.nella+ enables near real-time monitoring of Legionella contamination and supports rapid response to changing system conditions. If predefined limit values are exceeded, alarm notifications can be issued automatically. The system can also be configured to trigger automated biocide dosing in order to reduce Legionella concentrations as required.
INWAgreen
INWAgreen is a product range of biodegradable water treatment chemicals for industrial applications. The portfolio includes corrosion inhibitors for cooling and recirculating water systems, hardness stabilizers for scale control, and flocculants for wastewater treatment. The formulations are based on biodegradable and phosphate-free active ingredients. They are used to reduce corrosion, control the precipitation of hardness-forming minerals, and support the separation of suspended solids from wastewater. As such, they meet the same technical requirements as conventional water treatment products and can be integrated into existing treatment programs. By avoiding the use of phosphates and poorly biodegradable substances, INWAgreen products help reduce the environmental impact of water treatment processes. At the same time, they maintain the treatment performance required for reliable and efficient system operation.
