Dehumidification in the waterworks

Condensation is one of the biggest challenges faced by companies operating and maintaining equipment at water supply facilities, particularly during the warmer months of the year. The infiltration of warm, humid air into cooler buildings can lead to condensation forming on the pipes and fittings that carry the water, and other colder components.

This can cause considerable damage to technical systems and the building itself:

■ Corrosion of electrical contacts and damage to sensitive electronics

■ Droplet and puddle formation Mold formation and microbe growth

■ Clumping of chemicals and additives

■ Wet surfaces representing a safety risk for staff

■ Destruction of anti-corrosion coatings

Powerful dehumidification systems can effectively and efficiently protect technical equipment in water supply facilities from all kinds of moisture-related damage. They can also help to significantly reduce the amount of downtime required for maintenance by keeping equipment in peak condition. Plus, they keep the working environment safe and hygienic for staff.

Energy-efficient control
with dew point or surface sensors

Humidity is not directly regulated due to the inertia which, although distinctive in nature, is always present. Compressor and fan operation are activated via corresponding measuring and regulation functions in condensation dehumidifiers and the registration pack and fan in desiccant dryers. The following possibilities are available for the control of dehumidifying systems independent of humidity:


Available as electronic or mechanical version in many different models. Both ON/OFF operation and activation of compressor or regeneration pack without deactivation of fan possible.

Dew point sensor:

Dehumidification system is activated when dew point is undercut.

Combined temperature/humidity sensor:

If an additional temperature control is required.

The example in which dew point and ambient air humidity regulation are compared under identical conditions shows the enormous potential energy savings offered by a professional design tailored to the application, combined with the corresponding regulation strategy.
