Air Cooler Systems: How to Choose a Suitable Setup

It moves air across water-wetted media so evaporation removes heat from the airstream. Direct systems also add moisture; indirect designs use a heat exchanger to limit that effect.

Yes, the setup generally needs a way for air to leave the cooled area as fresh air enters. Follow the design and installation guidance for your particular system.

Direct cooling passes air through wet media and adds moisture. Indirect cooling transfers heat through a heat exchanger, so the supply air gains less moisture.

Use the service schedule in the owner’s manual. Water quality, dust and operating conditions affect cleaning needs, so inspect the system as the manufacturer directs.
