Operating aquatic centers is expensive. They consume the most energy per square meter of any municipal structure due to operation of pumps, filtration systems, lighting, and heating/cooling systems. When the facility is unoccupied, up to a third of their energy consumption is used. Balancing energy efficiency with the demands of maintaining water quality and indoor comfort is a challenge.

Maintaining a comfortable indoor climate is essential for the well-being of visitors. Aquatic centers need to regulate temperature and humidity levels to prevent discomfort, condensation, and potential damage to the facility and equipment.

Implementing energy-saving technologies, optimizing equipment usage, and exploring renewable energy sources can help decrease energy consumption.


Northern Air® Aggressive Environment addresses the unique ventilation issues presented by the high concentration of hazardous gases in the occupancy zone in aquatics centers. The concentration of, for instance, trihalomethanes (THM) above the water surface in a swimming pool is decreased by generating movement in the air. Additionally even out temperature and humidity variations is the mixing of the air layers.

An IP54 rated and C4 coated HVLS (High Volume, Low Speed) fan is the perfect solution to address the challenges faced in aquatic centers. With an IP54 rating, the system is highly resistant to dust and water ingress, making it suitable for the humid and moisture-rich environment of aquatic centers. The C4 coating provides an extra layer of protection against corrosion caused by chlorine and other chemicals commonly found in pools. By incorporating HVLS technology, this fan efficiently moves a large volume of air at a low speed, creating a gentle breeze that helps maintain comfortable air circulation while preventing strong gusts that could disturb the water surface. It also aids in controlling humidity levels by facilitating the evaporation of moisture from the pool area. This combination of IP54 rating, C4 coating, and HVLS technology ensures a durable, corrosion-resistant, and energy-efficient solution for the unique challenges faced in aquatic centers, enhancing the overall experience for visitors and staff alike.


The Aggressive Environment fan generates numerous benefits when deployed in aquatic centers. Its gentle breeze effectively circulates air, reducing stagnation, eliminating odors and curbing condensation. By controlling humidity, the fan maintains a comfortable indoor climate for visitors and staff. Additionally, features such as an IP54 rating and C4 coating ensure the fan’s durability by making it resistant to water, dust, and corrosion. Consequently, the fan’s presence enhances air quality, regulates humidity, and improves overall comfort within the aquatic center.

Gladsaxe Aquatic Center achieved a significant 30% reduction in energy consumption, mainly attributed to decreased electricity usage. This was accomplished by optimizing the ventilation system’s airflow through the efficient operation of fans, resulting in better air distribution and easier control. Specifically, the ventilation system’s airflow was reduced from 24,000 m3 per hour to 16,000 m3 per hour, resulting in substantial energy and cost savings for the aquatic center, as the system operates with a lighter load.
