Evaporative Air Coolers

A cost-effective alternative to conventional air conditioning systems

If your Building is situated in a region with a hot dry climate then installing an evaporative cooling system is an eco-friendly and cost-effective alternative to conventional air conditioning systems. It is also more energy efficient.

Air conditioners pump refrigerant (which produce emissions) through compression and evaporative cycles to cool building interiors. Evaporative cooling systems chill flowing air by evaporating water. Warm exterior air is blown by a fan through a dampened pad or heat exchanger. The airstream cools as the moisture from the pad evaporates into it, releasing cool air into the intended area. Key to the performance of the system is cross ventilation which is made possible by open windows and doors or designated ventilators.

Useful Information

Energy Consumption Savings

Uses around 60% less electricity than comparably sized refrigerant-based air-conditioning systems.

Evaporative Cooler Features

No need to close doors and windows when the evaporative cooler is in use. The cooler operates with cross ventilation exchanging indoor air with natural outdoor air. Guest enjoy a healthier alternative to conventional air-conditioning systems.

Portable Alternatives

Portable systems are also available

Additives to Enhance Performance

Strategically installed ventilators enhance the performance of the system by regulating the movement of air into and out of your building.

Vs. Traditional Air Conditioners

Evaporative coolers can generally cover a larger area compared to area covered by a same sized air-conditioner. The device is also less expensive to operate and maintain than a conventional air-conditioner although regular maintenance is still needed.

Controlling The Air Balance

Climate control inside buildings depends on proper air balance. To limit humidity, you need to make sure that the same volume of air flow exits and enters the intended area. This can be tricky.

Easy Installation

Installation is generally less expensive than a centralised conventional air-conditioning system.

Air Filtering Pads (Required)

The pad or pads included in the system serve as an efficient air filter eradicating contaminants found in the surrounding air.

Humidity Is A Factor

The cooling capacity of the cooler is reduced when the humidity is high. It has no dehumidification. As such it is not suited for regions with a high humidity factor.

Usage & Best Practice

The system relies on clean water, free of mineral deposits or high mineral content – mineral deposits may be left on the pads and the cooled interior if the water has a relatively high mineral content.

Maintenance & Servicing

The cooler device must be drained and cleaned periodically. The device could sometimes give off a bad odour if filtering foundation (pad) is not adequate or in a state of disrepair.

Running The Cooler Off Solar Electricity

It is possible to run evaporative cooling systems off solar power.
