Common Questions and Answers for Keruilai Industrial Cooling Fans!

　　1. How does an industrial air cooler work?

　　Industrial air coolers remove heat through evaporation of water to achieve cooling. This cooling method is lower cost and more energy-saving than traditional refrigeration technology.

　　2. What is the difference between industrial air coolers and standard fans?

　　Standard ceiling fans increase indoor air circulation by rotating blades, so sweat on the human body evaporates faster, but the cooling effect is limited. The fan cannot operate in a closed space or in an area where the air flow velocity is greater than 6.4 kilometers/hour. If the ambient temperature is higher than the natural temperature of the human body (37°C), the rotation of the fan blades can only heat the human body but has no cooling effect.

　　On the other hand, air conditioners can bring significant cooling effects to the surrounding air. By introducing moisture into the air and effectively circulating it, Keruilai's air conditioners/cooling fans (air conditioning fans) can significantly lower room temperature. Fans can only affect the body's perceived temperature, but air conditioners/cooling fans (air conditioning fans) can reduce indoor temperatures by about 5°C. The working principle of evaporative refrigeration of industrial air coolers is more reliable and stable than air circulation. Additionally, industrial air coolers are much less noisy than standard fans.

　　3. Does the operation of industrial air coolers consume a lot of electricity?

　　Air refrigeration is an energy-saving cooling technology. The operating cost of an industrial air cooler is one-tenth that of a traditional air conditioner. A 2.2-ton split air conditioner consumes 2,200 watts of energy per hour. A Keruilai air cooler uses almost the same amount of energy as a traditional ceiling fan. The energy required by Keruilai air coolers ranges from 105 watts/hour to 255 watts/hour.

　　Although the energy losses of ceiling fans and industrial air coolers are similar, the cooling effects are significantly different. Industrial air coolers have a wider cooling coverage, can really cool down, and operate with little noise.

　　4. Is it effective to use an industrial air cooler in a humid environment?

　　Although it works best in dry/arid conditions, air conditioners/cooling fans can still provide effective cooling as long as the ambient humidity is below the saturation point. In other words, when the air humidity is below 50%, the air conditioner/cooling fan can operate effectively.

　　The effectiveness of industrial air coolers will be reduced in moderately humid areas, but they can still achieve ventilation and air circulation effects. However, we do not recommend using Keruilai  air coolers in areas with high relative humidity .

　　5. What kind of wet curtain does Keruilai’s industrial air cooler use?

　　Keruilai air cooler adopts innovative honeycomb wet curtain. Honeycomb wet curtains have a unique cell structure similar to a honeycomb shape. This structure can produce a better cooling effect due to the increased surface area for humidity transfer in the air.

　　Both poplar wood and honeycomb wet curtains are all-natural and cost-effective. Evaporative air coolers remove heat through evaporation of water to achieve cooling. This cooling method is lower cost and more energy-saving than traditional refrigeration technology.

　　6. How to choose a Keruilai air cooler that suits my needs?

　　Keruilai supplies a variety of different residential air cooler (air conditioning fan) models, which are designed to meet different needs and different usage locations. Choosing an air cooler depends on several factors, including the size of your room, the local climate, the structure of your building, your budget, and your requirements for special features. Based on your needs, use Keruilai’s online calculation tool to choose the air cooler that’s right for you.

　　7. How to install Keruilai air cooler?

　　Keruilai air cooler is quick and easy to install. First, remove the air cooler from the box and remove the protective packaging. Depending on the model, place the industrial air cooler in front of a window or on a trolley. Carefully insert the water hose into the float valve. When filling the water tank, the air cooler cannot be connected to power and should remain turned off. Finally, plug the air cooler into a nearby electrical outlet and turn it on. Press the cooling button and wait for 1 minute until the water soaks into the wet curtain and you can feel the refreshing cool breeze. For optimal cooling performance, open all doors and windows.

　　8. Can the Keruilai air cooler be connected to an inverter to operate?

　　Can. All Keruilai industrial air coolers can be connected to frequency converters. Please make sure your frequency converter can output sine waves properly. The standard electrical type supplied by all utilities is sine wave, and all air coolers and most frequency converters operate to this standard.
