Humidity in technical rooms is a common challenge in water supply systems, where pipes carrying cold drinking water pass through warmer environments. The result is usually condensation, wet walls, dripping stainless-steel pipes, and, over time, corrosion and structural damage.
To address this widespread issue, many water utilities are turning to modern dehumidification systems, particularly adsorption dehumidifiers that ensure a stable and dry environment under every ambient temperature and constantly humid conditions.
This was precisely the situation at the Thuracker pumping station near Frauenfeld, in the Swiss canton of Thurgau.

Case Story: Thuracker Pumping Station
A dehumidification specialist from Cotes’ partner, Krüger, inspected the Thuracker facility and found puddles of water on the floor, condensation dripping from the pipes, and an overworked condensation dryer struggling to keep up.
Responsible for supplying drinking water to the municipality of Gachnang, the Thuracker station needed a reliable long-term solution to protect its critical infrastructure and ensure consistent operation.
After a detailed assessment, the C30E 1.9 adsorption dehumidifier was installed - a robust and efficient dehumidifier ideally suited for colder technical rooms and consistent humidity levels.
The Right Solution for Reliable Operation
Unlike traditional condensation dehumidifiers, adsorption dehumidifiers work effectively regardless of temperature. Moist air passes over a hygroscopic silica gel rotor, which absorbs water molecules. The absorbed moisture is then expelled through a separate air duct.
This process ensures constant, temperature-independent dehumidification: an essential advantage in waterworks, pumping shafts, and reservoir systems.
Key benefits for water utilities include:
- Corrosion protection for pipelines, fittings, and electronics
- Prevention of mould growth in poorly ventilated areas
- Dry floors and walls that enhance maintenance and safety
- Consistent indoor air quality to support hygiene standards
The Right Solution: The C30E 1.9
The C30E 1.9 model is engineered for continuous operation, with moisture removal capacity of up to 1.9 kg of water per hour, even in low-temperature or high-humidity conditions.
At Thuracker, the unit was positioned strategically to target areas most affected by condensation. About nine meters of supply air duct were installed to distribute dry-air throughout the technical room, with a shorter exhaust air duct routed through an existing wall opening.
The C30E performs reliably in environments with increased dust. It’s also easy to maintain, making it a practical solution for smaller plants with limited personnel.
Why Dehumidification Matters in Waterworks
Across Switzerland, nearly 3,000 waterworks face similar challenges. Many rely on natural ventilation alone, an approach that offers limited protection against humidity. Over time, this leads to rusting pipes, damp building structures, and even dangerous microbial growth.
Installing a dedicated dehumidification system is a cost-effective preventive measure. Adsorption dryers such as the C30E not only stabilise humidity levels but also extend the service life of facilities while maintaining hygienic operating conditions.
