Evaporative coolers are a great way to industrially cool your building no matter what the use.
We’ll cover how evaporative coolers work and a number of common configurations.

How does an evaporative cooler work
Traditional air conditioners use either compression or refrigeration coils which spike energy bills. Refrigeration coils can also contain CFC chemicals that are harmful to the environment. But an evaporative cooler uses the natural process of evaporation to cool air, because water absorbs heat in order to evaporate. It’s the same natural process used by your skin to cool your body.
Let’s dig into that a little more.
This is an example of a unit used for evaporative cooling. It’s the External EcoCooler small.
As you can see there is a fan on one side of the unit and a number of intake ducts on the other sides. The unit can be configured in a number of options as required.
Electricity is used to turn the fan which sucks external air through the intake ducts and pumps it into your building. The cooling process happens in the middle when the air passes through an evaporative cooling pad. This pad is damp with water which absorbs heat from the warm air in order to evaporate. The result is cooler air leaving the otherside of the pad and into your building.
4 steps to cool air
- Ambient air is drawn into the unit from outside.
- The air passes through an evaporative cooling pad.
- Heat from the air is used to evaporate the water, which reduces the temperature of the air.
- The cool air is pumped into your building by the fan.
Example configurations for an evaporative cooler
The cooling unit is only one part of the solution. After the air has been cooled it needs to get to the right place in your building, and the hot air needs to be removed. Below you’ll see a number of solutions to give you an idea of the options available. But they are only examples. Briggs Burners are experienced at working with clients to design the right solution for their building and operational needs.

EcoCooler with 8 way plenum chamber
A unit is installed on your roof and attached to an 8 way plenum chamber that has deflection blades.
In this configuration the chamber is high up in the roof because cold air falls. So as the cool air enters the building it is distributed evenly to the production area, and the cooling effect is felt as the air falls to the ground.
In the same principle, warm air rises and is then exhausted via an extraction fan in the roof.
The plenum chamber is great for evenly distributing cool air in all directions. But if you’d like spot cooling then instead of the plenum chamber we can install a pair of swirl diffusers. Here’s a visual example.
Evaporative cooler on the side of a building
It might be that you don’t want units and extraction vents on your roof. Or maybe the room you want to cool isn’t next to the roof. No problem.
An EcoCooler can be mounted to the side of your building. Air can be supplied by a fabric duct and then the excess hot air is extracted from the opposite wall of your building. This will help to move the air through a factory or warehouse. Especially if the hot air extraction is placed high up on the wall.
Cooling a room with a suspended ceiling.
As hot air rises it can sit in the void above a suspended ceiling. In this example, an exhaust is placed high up in the room as usual, then a number of ceiling tiles are replaced by extract grilles. This way the hot air is exhausted from the room in an efficient manner.
For cooling, the EvoCooler sits on the floor outside the facility and distributes its cool air by a split ductwork.
