Water Cooled Portable Air Conditioners OceanAire’s range of water cooled portable air cooler units include:

PWC Series (12,000 BTU/HR to 60,050 BTU/HR) OWC Series (12,000 BTU/HR to 60,050 BTU/HR) How Do Water Cooled Portable Air Conditioning Units Work? Portable air conditioner units that are water cooled simply require access to an appropriate power source, a source of water and a drain. Our units come equipped with hoses which will connect to any standard sink, but can also be used in janitor sinks or used with any other type of waste water outlet. There are many applications where a standard air cooled air conditioner cannot be used. Because they require ventilation to discharge the heat that they generate, ducts must be run through windows or into floated ceilings or other appropriate outlets, like a warehouse or other large spaces. This makes water cooled air conditioners far more versatile than air cooled portable air conditioners. Advantages of Water Cooled Portable Air Conditioners There are many advantages to using a water cooled air conditioner to cool a space.

Here are just a few: No exhaust / ventilation / hot air outlet required No negative air pressure caused by ducting Water cooled air conditioners work better in areas with high ambient temperatures (because they use water, not surrounding air to cool the condenser) They can be used in extremely hot areas – hotter than air cooled units can Offer a greater cooling capacity (5 ton air cooled single phase units require 50 amps / 5 ton water cooled require 30 amps OceanAire manufacture a range of commercial water cooled portable air conditioners for use in almost any environment. We have distributors across the United States and even across the world.

A cooling tower can be any size, from really gigantic down to the size of an automobile. In a cooling tower, air blows over water to create evaporative cooling, and this cooler water is used in the heat exchanger of, say, an air conditioner.

A more direct form of evaporative cooling is often found in greenhouses, farmers' markets and chicken houses. In these kinds of systems, water flows over a mesh, and a fan blows air through the wet mesh into the building. Humid, cooler air is the result.

Get an energy-efficient, portable evaporative cooler Evaporative coolers, also called swamp coolers, combine the natural cooling properties of water with a steady breeze to lower indoor temperatures. This guide will help you determine which type is best suited for your needs. Tip: Evaporative coolers are most effective in areas of low humidity and hot temperatures. They can be used as the sole cooling system, or to complement existing air conditioning systems.

They should never be used at the same time, however, as evaporative coolers add humidity and A/C units remove it. SHOP ALL EVAPORATIVE COOLERS How Do Evaporative Coolers Work? Evaporative coolers lower indoor temperatures by combining the natural cooling properties of evaporating water with an efficient air moving system. Evaporative coolers add moisture, with the water-filled pads acting as a filter, removing dust and allergens from the air. Evaporative coolers offer several benefits over air conditioning, including: • Lower installation and maintenance costs • 75 percent less electricity usage • Helps prevent fabrics and wood from drying out • Can be powered by standard 120 volt outlet • No ozone damaging refrigerants Evaporative coolers are not as controllable as air conditioners, and can use between 3.5 and 10 gallons of water per hour, a consideration for use in areas with limited water supplies. Evaporative coolers are typically distinguished by where they are installed and the type of pads they use.

Most whole-house evaporative coolers are mounted on the roof and blow air downward, while others are mounted through windows or walls and blow air in from the side. Down-flow installations are most popular, but window/wall-mounted horizontal units are more convenient for maintenance and reduce the chance of roof leaks. Both down-draft and window-mounted units blow cooled air into the house either into a central location, which is effective for small homes, or through existing or specially installed ductwork in larger homes. Tip: To ensure effective distribution, you’ll need to know how much air the unit needs to move to cool your home, which is measured in cubic feet per minute. • Cools small spaces up to 300 sq. ft. • Can cool one room or a garage • Installed on roof • Discharge cool air downward into the structure • Typically installed on side of building directly into the attic area • Can be installed on roof using an elbow to direct the airflow through opening in roof

The two types of pads for evaporative coolers are fiber (made of various materials) and rigid media pads. Fiber pads are inexpensive but require more maintenance and replacement, while rigid media pads are more expensive but require less maintenance and may last for years if properly maintained. • For units with inlets on many sides • Usually 1 to 2” thick • Require regular maintenance/replacement • Aspen wood is most durable; • Cellulose and synthetic may be cut-to-fit Stacked corrugated sheet material • For units with single inlets • Require larger upfront investment • Usually 8 to 12” thick • Allows air to pass through at lower velocity, resulting in increased humidity and air a few degrees cooler than with fiber pads • Extremely long lifecycle if maintained For the most cooling power, you’ll need to know how much air the unit needs to move to cool your home, which is measured in cubic feet per minute.

Evaporative coolers are rated by CFM. Use this formula to calculate the CFM for cooling your home: Determine the square footage of space you want to cool. Multiply this figure by the height of your ceilings. Divide that number by 2. The result is the CFM rating for the evaporative cooler you need. Keep the rust- and corrosion-resistant galvanized steel that most whole-house evaporative cooler housings are made of intact with monthly inspections. Regular maintenance per the owner’s manual is the best way to keep your evaporative cooler working at peak efficiency. Maintenance is usually centered on draining water to remove mineral buildup, and adjusting the belt and water levels. If the unit isn’t going to be used for a few days, it should be drained to reduce bacteria growth, which can also be controlled by adding one of several accessories before operation. Pads should be inspected, cleaned or replaced, as needed. Add any of these accessories to match your evaporative cooler to your specific needs:
