Coolair evaporative cooling uses evaporation to cool the air. Based on the principles of evaporation, hot and dry outside air is drawn through water-soaked cooling pads. As the air is pulled through these pads, the water evaporates and the heat in the air is absorbed, which lowers the air temperature. A fan then pushes the cool air throughout the building via a network of ducts.
The key to effective evaporative cooling is to ensure saturation of all cooling pads during operation and to size and design the system’s fan and motor to deliver the appropriate airflow for the space.
Evaporative cooling describes this natural phenomenon, however, there are many other terms that we might hear with the same meaning including evaporative air conditioning, adiabatic cooling, ducted evaporative cooling, swamp coolers, and desert coolers.

You can never go wrong when choosing Coolair evaporative cooling: Seeley International uses its NATA laboratory for accredited tests results to substantiate superior performance against competitive products and systems.Find a distributor in your country How does it work? Explore the benefits
Evaporative cooling uses evaporation to cool the air.
Hot air enters the cooling unit on the roof where it is filtered and cooled as it passes through specially designed moistened Chillcel™ pads. As the air passes through the cooling pads, the water evaporates and the heat in the air is absorbed, which lowers the air temperature. Finally, a fan pushes the cool air throughout the building via a network of ducts.
Seeley International has designed the most advanced technology to give you full control of your coolers in the smartest way. In fact, easy to connect, all products of the MagIQtouch® Controller suite are also easy to install & intuitive. Not just Supercool, but SuperSmart!
From the MagIQtouch touch screen controller, to the smart indoor and external air sensor, next generation control is available for your company. Moreover, you can connect the coolers to BMS system, for a full integration experience.Explore control options
The evaporative cooling process relies on airflow, with cool air entering through ducts and then exiting via open doors or windows or extract fans. For this reason, only 100% fresh air is circulating, rather than stale and recycled air.
Evaporative cooling is the perfect solution when cooling huge buildings, because of reduced running costs and high airflow. Indeed, it is the most suitable solution when traditional air conditioning is not an option.
Often commercial or industrial buildings have small spaces that are hot and uncomfortable to work in (because of heat from machines for example). In these cases, Evaporative Cooling can blanket the hot spot with a flow of cool, high velocity, fresh air, designed to positively impact your workers whenever they are in that hot location.
As the fan draws outside air through the cooling pads, this air is not only chilled but also filtered from impurities.
Evaporative cooling uses water to cool. This helps reduce the production of greenhouse gases, including harmful hydroflourocarbons.
Better for your pocket and for the environment. We have estimated that in a location like Jaipur in India, using a Seeley evaporative cooler you can reduce running costs up to 76%1 and carbon emissions up to 79%2.
The technologically advanced water management system continuously checks the quality of the water in your cooler. The system automatically replaces the water when mineral deposits exceed an acceptable level. The optimal result: minimum water use for maximum, fresh cooling power. Furthermore, you can generate your own cooling medium by rain water harvesting and to create a water neutral solution, you can use the waste water for grey, fire or irrigation.
When cooling large areas, the best option you can use is by far evaporative cooling, especially for industrial and commercial spaces. Air conditioning is not such a viable option, because in warehouses or industrial plants, the capital and running costs would be extremely prohibitive for end-users.
With increasing energy prices, and extreme temperatures making summer longer and hotter, evaporative cooling has a significant and increasing edge on direct expansion air conditioning when it comes to energy efficiency, performance and carbon impact.
In addition, we have estimated that using a Seeley International axial inverter evaporative cooler, you can save up to 76%1 on running costs over refrigerated air conditioning system performing the same duty, in a location in India.

Most industries with high heat loads, such as printing, ceramics, glass, rubber or electronics, have no cooling system installed, and this impacts on the workers’ morale and productivity, as well as on their health. Furthermore, in cases where they have traditional cooling systems installed, they rely on recirculating the air in the indoor space, which can be full of fumes and germs. Finally, premises such as warehouses or big storage rooms, especially when dealing with food and pharmaceutical products, have specific requirements of temperature.
In all these examples, Direct Evaporative Cooling could be the right solution. Evaporative Coolers do not use any sort of chemical refrigerants to cool the air, just a water pump to supply water to the wetted media where evaporation occurs and electrical power for the fan that pushes the cooled air inside the building. Many companies in Sri Lanka, India, Pakistan and overall Asia have already given trust to Evaporative Cooling: printing facilities, electronic manufacturing industries, automotive assembly lines and showrooms, ceramics, food industries, warehouses.
In addition, since Coolair evaporative cooling needs to extract stale air from inside the building, it is also suitable for semi-open spaces, such as car workshops, terraces or tents for events.
Evaporative cooling delivers a natural, exceptionally healthy cooling experience in the place where people spend most of their time, at work. It uses a fan to push outside air through water-soaked cooling pads to bring an endless supply of cool, fresh filtered outside air into the building, leaving moisture in the air, which combats dehydration and illnesses such as asthma.
Building ventilation is becoming a concern for all businesses, to ensure indoor air quality is maintained. Business owners need to guarantee a safe workplace for employees and minimize risk of contamination for all patrons. Therefore, we have collected the latest Covid-19 containment guidance from most important independent associations, to explore requirements and suggestions.
