Indirect Evaporative Cooling for Makeup Air
S Flo, is specialize in advanced ventilation technologies that reduce energy use while maintaining indoor air quality. Our indirect evaporative cooling(IEC) systems are engineered to condition makeup air the fresh outdoor air that replaces exhausted indoor air without adding humidity.
This is ideal for commercial and industrial environments such as data centers, food processing facilities, manufacturing plants, and healthcare buildings that require high volumes of ventilation without compromising comfort or compliance.
How It Works?
Air Intake
Outdoor air enters the system as makeup air.
Evaporative Cooling
A separate secondary airstream is cooled through a wetted heat exchanger.
Heat Exchange
The cooled secondary air absorbs heat from the makeup air stream without direct contact.
Delivery
The result is clean, cool, dry air supplied into the building.
This closed-loop approach ensures energy-efficient cooling while maintaining stable humidity and airflow.
