Types of Water Cooling Systems: Closed-Loop Dry System

A closed-loop dry cooling system utilizes an air-cooled fluid that removes heat from the closed-loop fluid. Closed-loop dry systems are comparatively cheap to operate. We’ll guide you through the basics of this cooling system type.


Low Maintenance

Closed-loop dry cooling systems are relatively easy to install and they don’t require as much energy to operate as other cooling methods do. Maintenance costs are normally quite low, usually only requiring inspections once or twice a year. The fluid cooler will occasionally need cleaning to remove dirt, leaves, and other debris that can build up in the system over time.



One downside to a closed-loop dry cooling system is that it needs clear, clean air to operate efficiently. The fluid cooler should be placed in a location where it won’t be affected by wind, but also not too close to a building, so that air leaving the fluid cooler can properly circulate back into the system. In addition, the system should be placed in an area free of excessive dust, dirt, pollen, and leaves. In most climates, a good location for a fluid cooler is the building’s roof.


Water Conservation

What’s one of the biggest advantages of a closed-loop dry cooling system? Conserving water. A closed-loop system uses a set amount of water which it reuses for months or years, reducing water consumption by up to 98%.

Choosing a closed-loop dry cooling system for a new or existing building can be a great option for many applications, but it takes a lot of planning. Make sure you speak to a supplier with experience and expertise not only in the system design, but also in industries and optimal installation.
