Evaporative cooling is one of the oldest and most natural forms of climate control. This process occurs when hot, dry air absorbs moisture as it passes over a body of water. As the water evaporates, the air is cooled and energy is exchanged resulting in lower air temperatures. Today, this process has been refined for natural and efficient home cooling.

The coolers lower indoor temperatures by combining the natural cooling properties of evaporating water with an efficient air moving system. This combination of moisture and a steady breeze can lower indoor temperatures by as much as 30'F. Airflow is controlled by opening windows to allow the unit to push warm air outside.

Evaporative coolers are typically distinguished by where they are installed and the type of pads they use.

Aspen Media Pads are made from aspen tree fibers, held together in a pad form with a thin plastic netting. This form of media is durable and economical.

Rigid Media Pads are designed to operate at maximum efficiency with minimal maintenance, 8” and 12” media depths are available. These pads have an extremely long lifecycle if maintained properly.

Polyester Media Pads are made from random fiber distribution. The fibers are laid in all directions throughout the web to create a unified media. This offers more cross-over points which help trap dirt and particles.

Benefits of Evaporative Cooling

By ensuring proper moisture levels, evaporative coolers reduce static electricity, protect fine furniture and wood flooring, and moisturize dry skin. Evaporative coolers work hard to reduce airborne particles and dust while also minimizing the spread of infection.

So, why use evaporative cooling instead of conventional AC? Traditional air conditioning reduces moisture levels and recycles the same indoor air. Whereas, evaporative cooling works to maintain proper humidity levels while producing fresh air.
