Swamp Coolers

Swamp Coolers Operating Principle:

A swamp cooler lowers the temperature of air by evaporating water, similar to the way the human body cools itself by sweating. The heat from warm, dry air is absorbed by the evaporating water and the result is cooler air with a higher moisture content.

A fan in the swamp cooler moves air to be conditioned through damp pads moistened with water that is continuously pumped onto the pads.

Warm, dry conditions are best for swamp coolers – humid air absorbs less water and heat, providing less cooling.

Benefits of a Swamp Cooler:

• Low maintenance
• Very reliable, only moving parts are fan and pump
• Lightweight
• Fast, easy setup
• Uses less energy than compressorized air conditioner

How well a swamp cooler cools a house:

Information from the Arizona Almanac by Ed Phillips.

Swamp Coolers and Things to Consider:

• High humidity decreases cooling capacity. For example, at 90 degrees F and 10% relative humidity, a certain model evaporative cooler will discharge air at 65 degrees F. At 90 degrees F and 50% relative humidity, this same cooler has a discharge air temperature of 78 degrees F.
• Leaving air is 80-90% relative humidity and may cause corrosion, condensation, or discomfort
• Water is required to wet the evaporative pads and is typically supplied by manually filling an internal tank or hooking up to an external water source for automatic continuous operation

Swamp Cooler Configurations:

Most evaporative coolers are mounted on wheels to they can be easily moved. Smaller units have internal water tanks, and larger units have external tanks. Standard 3/4" hose connections are common for all capacities and allow automatic water fill and continuous operation.

Swamp Coolers - Installation Overview:

1) Fill water tank or connect to external water source.
2) Plug it in.
3) Start up and fine tune direction of cooling airflow.

Swamp Coolers - Increasing the Efficiency and Lowering Energy Requirements:

1. Once you purchase a swamp cooler, make sure that you set it up per the manufacturer’s recommendations.

2. Open a window and/or provide adequate ventilation. If the air indoors becomes too humid, the swamp cooler will not be able to evaporate water as rapidly and as a result will not be able too cool the area as efficiently.

3. The warmer the surrounding air, the more water can be evaporated. The greater the difference in temperature between the cool water and the hot air, the more efficient your swamp cooler will be. So, don’t try to cool your house just a degree or two. Wait until it is sufficiently hot (Usually mid-80s).

4. Keep your evaporative pads clean. If they become clogged, they will not work efficiently. Impurities on pads will prevent the maximum amount of water from being evaporated and decrease the efficiency of a swamp cooler.

5. Do not run a swamp cooler and air conditioner at the same time. The two operate on almost opposite principles. This will prevent either from working efficiently. This is huge waste of energy and environmentally unfriendly.

6. Finally, keep water in your swamp cooler. If the cooling pads become dried out, there will be no water to evaporate and no cooling will take place.

Availability: Time from order placement until shipment is 5-10 business days.

Shipping: As always, shipping in the USA (lower 48 states) is included. Swamp Coolers less than 100 lbs ship via UPS Ground. Larger swamp coolers ship via truck (FedEx Freight, Roadway Express, Old Dominion, etc). Local pick-ups at the factory are not allowed. Please contact us for shipping quotes to Hawaii and Alaska.
