Spotlight: EC220W Luma Evaporative Cooler
The EC220W Luma evaporative cooler is on of the largest and most powerful coolers on the market today. It has a sturdy design and stronger output perfectly tailored for large areas, such as patios, gyms, factories, play fields, barns, greenhouses, and foyers.
How the Luma EC220W Evaporative Cooler Works
Luma evaporative coolers through the process of evaporative cooling, a natural process identical to the one your body uses to control its temperature. Using a pump, the cooler draws water up from a storage tank and inundates a specialized cooling pad positioned in front of a high-powered fan. The fan pulls in hot air from outside and blows it through the pad. When the water in the pad comes into contact with the air, it evaporates and lowers the air temperature. The cool air is then blown out into the surrounding environment, cooling you off.
Because it relies on evaporation, the EC220W Luma evaporative cooler works best in areas with low relative humidity. Relative humidity is the ratio between the amount of water vapor in the air (actual vapor pressure) and the maximum amount of water vapor the air can hold (saturation vapor pressure). As the water level in the air gets closer to the saturation point, evaporation slows. There is less room in the air for the water vapor to move into. When humidity levels reach 100, the air stops accepting water vapor and whatever water is in the air condenses back into liquid again. Hot areas away from the ocean tend to have low humidity year round. Heat forces air molecules further apart, which increases the saturation point, and the further removed you are from water, the less water vapor is generated by the environment. Relative humidity is tracked by a number of organizations, such as Weather Central, which makes it easy to track the average humidity of your hometown . Evaporative coolers work best in areas with less than 60 percent relative humidity on a daily basis.
Electricity & Ecology
Because evaporative cooling is a natural process, evaporative coolers are some of the most economical and ecological utilities on the planet. Households with air conditioners run them for eight hours a day, on average, which costs them $38.52 every month and releases over 4000 pounds of carbon dioxide into the atmosphere ever year. Running a Luma evaporative cooler for eight hours a day costs only $6.34 a month, on average and releases only 670 pounds of carbon dioxide into the atmosphere every year, which means they save money and the environment.
The Luma EC220W is uniquely designed for maximum cooling. It's large, but compact. Three-and-a-half feet high and weighing 41 pounds, it's one of the lightest coolers in its class. It has 4 lockable wheel castors so you can move it wherever you need it and two side vents that increase air exposure and speed the evaporation process. The 10 gallon water tank allows the cooler to run for approximately 5-6 hours in a dry environment, and even longer in a wet one. The tank also has a hose attachment, which allows you to feed in water continuously and run the cooler almost indefinitely.
The EC220W Luma portable evaporative air cooler uses three high efficiency, rigid honeycomb cooling pads. They're made of specially engineered cellulose paper. It's resistant to rot, even after prolonged water saturation and the honeycomb design increases it total surface area, so more water comes into contact with the air. This means the EC220W has a greater evaporation rate and generates cold air more quickly.
One of the most common drawbacks of evaporative coolers is rust. Evaporative coolers generate a large amount of water vapor and constant exposure to water can corrode the casing and inner workings of evaporative units if they're used for an extensive period of time, but the EC220W Luma evaporative cooler is actually impermeable to oxidation and rust. It's body and casing is made from ABS plastic, a highly durable thermoplastic polymer resistant to heat and impact. The ABS plastic casing not only protects the unit from collisions, but also from cracks caused by temperature fluctuations and chemical evaporation. Its metal components, the fan blades, are made of aluminum, which is naturally coated with a impenetrable layer of aluminum oxide that prevents them from coming into contact with the high levels of water and oxygen inside the cooler.
The EC220W is simple and straightforward to operate. Just fill up the water tank using the either water inlet at the back of the cooler or by attaching a hose to the continuous water inlet next to it using the hose connector, PVC pipe, and metal clamp accessories. The large end of the hose connector fits over the continuous water inlet. Insert the PVC pipe into the narrow end of the hose connector and insert the hose into the PVC pipe. Secure them with the metal clamp and the hose will supply a steady stream of water into the tank once it's turned on.
Once the tank is full, set the fan speed by turning the "FAN" switch to low, medium, or high. The higher the setting, the more evaporation takes place as the air moves through the cooling pad. Once the fan is going, activate the water pump by turning the "COOLING" switch to "ON." You will have to wait a few minutes for the water to soak into the cooling pad, but once you feel cold air coming out, you'll know it's working. Remember to check the water level periodically and refill the tank as needed. If the unit has stopped working, a dry tank is the most likely reason.
In order to ensure the unit's weight is fully supported, always make sure the EC220W is positioned on a level surface and the wheel castors are locked before you turn it on. Evaporative coolers require air circulation to operate. Otherwise, in a closed room, the water vapor released by the cooler becomes trapped and builds up. This not only hampers the cooler's ability to cool the air, but also interferes with your body's ability to regulate your internal temperature. Always make sure to place the EC220W in a ventilated room with at least one open window, more if possible. If humidity does get too high, turn off the "COOLER" and just let the fan run. It'll circulate the air and cool you down better in a humid environment.
To get the best temperature, start your cooler early in the day. It'll be easier to maintain a low temperature than it will be to lower the temperature once it's gotten up too high. Many users even put ice or cooling packing into the tank to chill the water before it hits the cooling pad. The idea is that by increasing the temperature differential between the air and the water will accelerate its evaporation and create colder air.
Cleaning & Maintenance
The EC220W Luma evaporative cooler is a sturdy, low maintenance unit. Follow a few, simple guidelines and it should provide no difficult in normal, day-to-day operation.
|Clean the cooling pads once a month. Prevents them from becoming clogged||Remove the back panel with a screwdriver. Remove the cooling pads and rinse them with water. If there's hard water buildup, soak the pads in diluted vinegar for 30 seconds then rinse. Let the pads dry completely before returning them to the unit|
|Empty the water tank every month. Prevents hard water buildup||Remove the back panel and take out the cooling pads. Pull the drain plug from the bottom of the unit. Drain remaining water. Remove the tank and rinse it with warm light and light detergent. Wait for tank to dry before returning it to the cooler|
|Clean water pump every six months. Eliminates hard water build up||Drain water tank and pour a calcium lime cleaning mixture (e.g. CLR) into the tank. Close tank and let the pump soak for 10-20 minutes. Remove cooling pads and run the unit for 30 seconds max. Drain and rinse tank. Refill with clean water and run for 3-5 minutes to clean out the calcium lime solution. Replace pads and resume normal operation|
Dirt and grime on the outside of the unit can be wiped away with ordinary soap and water. Use a sponge or soft cloth to avoid scratches.
Is An EC220W Right For You?
The EC220W is Luma's largest evaporative cooler. Capable of cooling up to 650 square feet, it can produce enough air to fill most apartments and small houses, but its specialty is large spaces, recreation areas, and industrial worksites. One or two is enough to cool a loading bay, playground bleachers, a busy work station, or home patio. It's a high volume cooling solution designed for space and durability.
