Direct Evaporative Cooling

Direct evaporative cooling uses the natural process of evaporation to cool the air. Hot air enters the cooling unit, where it is filtered and cooled as it passes through specially designed wet pads. As the air flows through, the water evaporates, absorbing heat from the air and lowering its temperature.

Direct evaporative cooling offers several key advantages

100% fresh air is supplied into the space, and the strength of evaporative cooling lies in its high airflow volume, which provides not only effective cooling but also excellent ventilation. During this cycle, cool air is introduced indoors while stale, low-quality air is expelled outside.

Superior Ventilation – A much better solution compared to traditional air conditioning systems that simply recirculate the existing indoor air. Evaporative cooling is an ideal choice for large spaces where humidity levels are not a critical factor for people or production processes, thanks to its significant energy savings and reduced cooling costs.

If dry air is required without increasing humidity in the space, CLIMATE WIZARD units offer a unique solution – indirect evaporative cooling without adding moisture. This is the only adiabatic cooling system of its kind, made possible by patented M-Cycle heat exchangers.

Spot Cooling – Commercial and industrial buildings often have smaller areas or zones within large halls that become hot and uncomfortable to work in, typically due to heat generated by machinery. In such cases, evaporative cooling can have a positive impact on your workers by delivering high-velocity fresh air that flushes out hot air from critical hotspots, improving comfort and safety precisely where it’s needed most..

Coolair and the Environment

Reduced Greenhouse Gas Emissions
Evaporative cooling uses water as the cooling medium, significantly reducing the production of greenhouse gases, including harmful fluorocarbon-based refrigerants.

Energy Efficient and Environmentally Friendly
For example, at a location like Madrid (Spain), using an evaporative air conditioning system with a heat exchanger can reduce energy costs by up to 86% and carbon emissions by up to 90%.

Minimal Water Consumption
Seeley International continuously improves its water quality management system to reduce consumption. The system automatically replaces the water when mineral buildup exceeds acceptable levels. The result is minimal water usage while delivering maximum cooling power and fresh airflow. Additionally, you can create a water-neutral solution by collecting rainwater, and even use greywater to operate our systems.

Evaporative Cooling – The Best Option for Large Spaces

When it comes to cooling large areas, evaporative cooling is the most effective and sustainable solution, especially for industrial and commercial facilities. Traditional air conditioning systems using refrigerants are often not viable, as cooling represents one of the highest energy costs in warehouses and industrial plants.

Wide Range of Applications for Coolair Evaporative Cooling
Many high-heat industries—such as printing, rubber, ceramics, glass, and electronics—often operate without any installed cooling systems, which negatively impacts worker health, morale, and productivity. Even in facilities where conventional refrigerant-based systems are present, they rely on recirculating indoor air, often resulting in poor air quality with excessive fumes and microbial contamination.

Warehouses, particularly those storing food or pharmaceutical products, have specific temperature control requirements. Coolair units do not use any chemical refrigerants. Instead, they rely solely on water to supply the wet media in the heat exchanger, where the cooling occurs through evaporation. Power consumption is minimal, as electricity is only needed for the water pump and the fan that distributes the cooled air throughout the space.

Trusted by Industry Across Europe
A growing number of companies across Europe have turned to evaporative cooling: the metal and machinery industries, rubber and glass production, food processing, printing houses, electronics manufacturing, automotive production lines, showrooms, warehouses, schools, sports centers, gyms, banquet halls, commercial kitchens, restaurants, and more. The range of applications is all around us.

This system is also perfectly suited for semi-open areas such as auto repair shops, terraces, or tents.
