Evaporative cooling is a fundamental natural process.
A common and simple example is when you step out of a hot shower, even on the hottest days, and your moist skin feels cool. This happens naturally, without intervention or mechanical devices. Sweating, which helps humans cool off, is another illustration of evaporative cooling at work.
But how does it work, really?
The water doesn’t get cold; it absorbs heat. In scientific terms, the phenomenon is called the “latent heat of evaporation.”
As water evaporates, it turns into a vapor. Heat is absorbed during the process of what scientists call “phase transition,” in this case changing from a liquid state of matter (water) to a gaseous one (vapor).
Fresh from a shower, you feel a chill not because the water cools off but because the water absorbs heat from your body.
Flash-evaporative cooling magnifies natural process
The patented CULER Flow Blurring® technology atomizes water into millions of micro-droplets. The water itself starts out at room temperature, but as uniform, tiny particles they evaporate instantly, or flash-evaporate.
In this case the particles absorb heat from the air.
By creating more water surface area, the CULER technology achieves a faster rate of evaporation. CULER flash-evaporative coolers are efficient, too, with only the addition of a little electricity and Flow Blurring® technology.
CULER builds on nature’s evaporative cooling efficiency
Our process is more efficient and less messy than traditional pad-type evaporative coolers, which drip water down a pad, usually made of wood fiber, to create more surface area. A so-called “swamp cooler” pulls air through a large wet pad to create a cooling effect, which uses a lot of water and a lot of energy.
Based on independent laboratory test data, CULER flash-evaporative air coolers produce cooler air than similar size, pad-type devices.
For example, with an ambient air temperature of 90º F and relative humidity of 25 percent, the air exiting a pad-type evaporative cooler was 4 degrees cooler than the ambient temperature, while the air exiting a CULER SOLO was 22 degrees cooler.
Each of the CULER SOLO, CULER DUET and CULER Pro requires only a standard three-prong outlet to operate. Home use costs pennies of electricity per day. The commercial models cost pennies per hour to run. The home flash-evaporative coolers use 1 gallon of water. The tank for the Pro line is 20 gallons.
Our approach uses less energy, no chemicals and is easier on the wallet and the environment.
