Evaporative cooling units only use water to cool the air. Depending on the technology that we consider, water directly or indirectly cools the air. For direct evaporative coolers, hot outside air is drawn to a series of water-soaked cooling pads: the water evaporates and the heat in the air is absorbed, which lowers the temperature of the air.

With Seeley International indirect evaporative cooling units, water does not come in contact with the air stream, therefore no humidity is added to the airstream, reaching lower temperatures than direct evaporative cooling units.  To learn how Hyper-efficient Indirect Evaporative coolers work click here: How Does It Work

In commercial/industrial environments you will be using your evaporative cooler during the hottest part of the day, when the humidity is typically lower. With direct evaporative cooling systems humidity increases slightly, importantly extract fans need to be installed or doors and windows to be kept open. This way, stale humid, hot indoor air can be pushed out and replaced with 100% fresh outside air. If humidity is still an issue, it is better to specify Seeley International patented indirect evaporative cooling system, Climate Wizard technology.

Evaporative cooling units only use water to cool the air (no chemical refrigerants are involved in the process). They use far less electricity compared to refrigerated systems: that all adds up to very responsible environmental and energy saving solutions.

No matter how hot it gets outside, evaporative coolers use the same amount of power and still deliver 100% fresh, cool air inside. This is in direct contrast to refrigerated systems, which require increasing amounts of power as outside temperatures rise. Evaporative cooler cost-saving capabilities actually increase, when the ambient heat is at its peak. At the same time, their performance also increases as temperatures rise – again, in complete contrast to refrigerated systems.

Plus, evaporative cooling units use 100% outside air, whereas traditional air conditioning systems keep recirculating the same stale air, to achieve cooling efficiency, thus negatively impacting on Indoor Air Quality.

Moreover, when installing a traditional air conditioning unit, capital and running costs could be prohibitive for end users. Installing evaporative cooling units can be far cheaper, plus running costs can be up to 80% less than standard A/C performing the same duty.

Depending on the technology you will be choosing, our local partner (or Seeley International) will calculate the estimated number of coolers needed for your specific application and air conditioning requirements. We want to make sure your space is correctly sized with the right number of coolers, so do not hesitate to get in touch with us. 

Evaporative cooling is one of the most efficient options for cooling large areas, especially industrial and commercial spaces. Air conditioning is not a viable option, because in warehouses or industrial plants, the capital and running costs are   prohibitive.

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 and well-being. In all these examples, Evaporative Cooling can be the right solution.

Moreover, many industrial spaces have some areas that are uncomfortable to work in, because of the heat produced by machines or ovens, for example. No need to cool the entire space: evaporative cooling units could blanket these hot spots with a flow of fresh cooled air.

Evaporative Cooling units by Seeley International do not use much water. A Breezair TBS 580 evaporative cooler consumes around 18 liters per hour: but when considering water consumption, we should also refer to the water used to produce electricity (7.6 l/kWh[1]). An evaporative cooler could consume up to 30% less water than a standard A/C system installed in a similar application, if we also take into consideration the electricity needed to run the system itself.
