2 Speed Evaporative Cooler Motor

Product Details:

An evaporative cooler, also called swamp cooler, desert cooler, air cooler or water cooler, is a device that cools air through the evaporation of water. The first cooler was built in 1908 in Phoenix, Arizona. Our 2 speed evaporative cooler motors are often used in such kind of devices.

As is known to all, water absorbs a large amount of heat from air when it evaporates, which is a easy-known physical principle. The inventor of evaporative cooler just used this basic knowledge to develop the environment-friendly device.

Basically, an evaporative cooler consists of housing, 2 speed evaporative cooler motor, blower or fan, pads and pump. Negative press is formed in the cavity of cooler after the motor runs, which leads to outside air passing through the water-saturated pads to get into the cooler. Meanwhile, the mass of water on the pads evaporates due to the forced air flow, which absorbs plenty of heat from the passing by air, therefore, the temperature of the air drops quickly. As a result, the cooled air from the outlet of the cooler is kept delivering.

Different from other air conditioning systems, evaporative coolers don't product any harmful waste, only take the advantage of the physical evaporation. That's why it is also called environmental protection air conditioning.

Since the air flow of the cooler keeps one way, the water vapor evaporating from the pads flows along with the cooled air in the same direction, which increases the humidity of the cooled air greatly. In some particular applications, such as textile and garment industry, humid air is good for production and quality.
