A Coolerado air conditioner is multi-award winning and the most efficient air conditioning system made. It provides fresh, cool and healthy air while using about one tenth of the electricity of traditional air conditioning systems – saving customers on their energy bills. Coolerado air conditioners have won the R&D 100, the Governor’s Excellence in Renewable Energy, the Western Cooling Challenge and the Popular Science Best of What’s New – 2009.

Along with providing a more comfortable cooled space, Coolerado air conditioners save you a lot of money on your electricity bill and are healthier for you and the planet. They provide filtered, fresh and cool air without using any chemical refrigerants – such as Freon or other CFCs (H80 hybrid unit uses R410), and they reduce environmental impact by using a fraction of the electricity of traditional air conditioning units.

This depends on the climate. Factors such as outside temperature, level of humidity and water quality all play a role in determining the amount of energy usage. Coolerado units are capable of operating on about one-tenth the amount of electricity of a traditional air conditioner, that equates to less than the amount of energy used to operate a hair dryer.

Coolerado equipment costs are comparable to the most energy efficient traditional air conditioners on the market.

Because of Coolerado’s extremely energy efficient systems, most customers realize a complete payback within two to three cooling seasons.

Coolerado air conditioners are equipped with our patented HMX systems and using the Maisotsenko Cycle, are the most efficient air conditioning systems made. They provide dry, cool and healthy air, while only using about one tenth the electricity of a traditional air conditioning system.

The patented Coolerado Heat and Mass Exchanger was developed to economically take advantage of the Maisotsenko Cycle. A Heat and Mass Exchanger (HMX) consists of several plates of a special plastic that is designed to wick water on one side and transfer heat through the other side. The plates are stacked, separated by channel guides to provide structure to and direct air movement within the HMX. The channel guides divide the incoming air stream into product air and working air. The product air is cooled sensibly (rejecting its heat to the working air), and can be designed to cool below the wet bulb temperature of the incoming air stream. The product air travels the distance of the exchanger and into the space designated for cooling.

The working air initially enters dry channels where it is pre-cooled sensibly before it is fractioned into multiple streams which are directed into wet channels. The heat from the product air is transferred to the working air in the wet channels by means of evaporation (mass transfer and state change). The heat is exhausted out the sides of the HMX and then to the atmosphere.

This process occurs multiple times in a short physical space within the exchanger, resulting in progressively colder product and working air temperatures.

Essentially, the Maisotsenko M-Cycle is the heart of our cooling system – and is based on the discoveries of our Chief Scientist, Dr. Valeriy Maisotsenko. The M-Cycle is best explained through our two-part video series. Basic aspects of the M-Cycle are reviewed in this video, and a more in-depth explanation of the M Cycle, is presented in this video as well.

Coolerado air conditioners use the same latent* cooling process that transfers heat to a thunderstorm. Water is evaporated into air in one chamber within the air conditioner, and this cools the air flowing in an adjacent chamber. The cold air is used to cool the building while the water vapor holding the heat is exhausted to the outside to be renewed by the atmosphere. This ensures the freshest air possible is delivered to the customer.

*Latent Energy: Undeveloped energy that is capable of being converted into usable energy under suitable conditions.

The cool air provided by the M30, M50 and C60 models is the same humidity ratio as the outside air. Our newest commercial roof top unit (RTU), the H80, is capable of providing a small amount of dehumidification and is optimal for commercial applications.

Depending on the application, Coolerado air conditioners can be used in any location. While “high and dry” is optimal, many commercial and industrial applications do not require low humidity or temperatures below 80°F (such as a restaurant needing makeup air in a kitchen) and Coolerado is a great solution for those needs. Coolerado air conditioners work well in “low and dry” climates also.

No, the humidity is at optimum levels in the summer months throughout most of the western USA, including the deserts. Traditional air conditioners dry the air out too much in this region, causing many people to run humidifiers to make it more comfortable.

Direct evaporative air coolers add too much humidity. When the air becomes too humid, the skin cannot evaporate moisture off easily and use the body’s natural cooling system. This humidity, and the musty smell that sometimes comes from such a cooler, is why many people refer to a direct evaporative cooler as a “swamp cooler”.

There is direct evaporative cooling advertising stating humid air feels colder. That is true for temperatures 50°F and colder; however, in the summer months, room air is generally held at about 70°F or above, where high humidity feels like a swamp. Skin becomes clammy and can’t evaporate water easily.

Coolerado air conditioners use up to 90% less electricity depending on the humidity and elevation above sea level. As a result, electrical demand is significantly reduced, thereby reducing the amount of pollutants created by power plants. The hotter it is outside, the better Coolerado air conditioners work, making them much more efficient than traditional air conditioners during peak cooling periods*, and further reducing peak power loads. In addition, Coolerado air conditioners do not use any chemical refrigerants*, and the hearts of our air conditioners are made from completely recyclable materials, so if they ever wear out, they won’t clutter up our landfills.

*Hybrid H80 unit uses R410.
*Peak cooling periods: The period of time during the day that power plants are producing and consumers are using the most energy.

There are several variables that determine how much air is needed. These include the size of the space being cooled, activities taking place in the space, desired temperature in the building, moisture in the outside air, temperature of outside air and altitude. Generally, you need about as much airflow as a traditional air conditioner for the same heat load.

Coolerado air conditioners can be controlled with standard heating and air conditioning thermostats.

No, Coolerado units allow dissolved minerals in the water to wick out and flow down an incline where minerals are flushed away to the drain.

In some cases, these water sources can be used as an alternative to fresh water by:

• Filtering out un-dissolved minerals
• Determine the Total Alkalinity as measured with a pool water test strip. This must be less than 250 Parts Per Million, PPM.
• If there are dissolved organics in the water, they may need to be removed – such as in a water treatment plant or a continual addition of chlorine, or some other biological killing chemical.
• Hard water, (presence of calcium and magnesium in the water, represented by a total alkalinity being over 150 PPM), along with soap will create soap scum that could create problems.

Coolerado cannot know the details of your water supply and therefore how the water will react with our evaporation process. You should have your water tested first to properly address any water quality concerns.

The average amount of water used for our 6-ton residential unit will be about 4 to 6 gallons per hour depending on the climate and water quality. It will consume more water during the day through peak periods* and less in the evenings and transitional seasons.

Even with the high water rates in desert climates, it will generally cost less than $15 per month to supply water to our 6-ton unit. Assuming average electricity rates during the summer months, a consumer would likely spend a total of less than $60 per month.

Additionally, Coolerado air conditioners are net-zero water products.

*Peak periods: The period of time during the day that power plants are producing and consumers are using the most energy.

Power plants use water as part of their process to create electricity – therefore products that use a lot of energy require power plants to use more water to create the electricity required.

Traditional air conditioners use 80% to 90% more electricity and energy than Coolerado air conditioners – therefore, requiring more water to create this needed power.

Coolerado air conditioners use water as part of the operating requirements. Net-zero water usage means that the amount of water used by the electrical power plant to generate electricity, combined with the amount of water a Coolerado unit will use, is less than or equal to the amount of water a power plant would use to produce energy for a traditional air conditioner.

This is referred to as being net-zero water, or net-water neutral.

No water softener is needed, just a 5 micron water filter immediately before the Coolerado unit.

Coolerado’s plate material is a polypropylene with a biocide impregnated into it to keep organics from growing. If water is heavy with organics then that would be a case to pre-treat the water.

Yes, Coolerado air conditioners are compatible with photovoltaic (PV) systems. This application uses our Electronically Commutated Motor (ECM) which allows for significantly greater power generation from the PV system by ducting Coolerado exhaust air behind the PV panels (to cool them).

We currently have an award-winning, commercial Roof Top Unit (RTU)* with an optional heat application that will be in limited production in 2011. For more information on the H80, please visit the Products section on the Coolerado website.

*Roof Top Unit (RTU): Acronym for Roof Top Unit. This is an air conditioner model type that is utilized for commercial application. These units are typically larger and much heavier than residential air conditioners.

If the intake air of a Coolerado residential system is not ducted, the noise level is less than 70 dBA at a distance of 1 meter – which is about the same as the noise generated by the condenser* of a traditional air conditioning system. If the intake is ducted, the amount of noise can be substantially reduced.

*Condenser: An apparatus utilized in traditional air conditioners that cools and removes humidity from the air as it passes through into the building.

Maintenance needs are dependent upon the local water quality, as well as the outdoor air quality. Under normal conditions, there is a start-up procedure at the beginning of each cooling season that includes removing any winter duct blocking, ensuring the filters are clean, checking the fan for obstructions, cleaning and filling the water strainer with a liquid soap, turning on the water valve and powering up the unit. The water strainer needs to be cleaned more or less frequently depending on the quality of the local water. Air filters need to be replaced monthly to seasonally, depending on the amount of dust in the outside air. This is no different than changing the filters on a furnace. There is a winter shutdown procedure to drain the water, as well as dry the unit out. These general maintenance procedures are simple to perform and quick to complete.

It depends on the air quality, but usually once a quarter, which is about $20 USD.
