Coolerado Cooler

Coolerado is revolutionizing data center cooling with its new patented M50 cooler. It uses up to 90% less energy than traditional air conditioners, and it’s payback for data center installations is less than a year. Coolerado is perfect for the southwest region of the United States, where the climate is dry and arid. The M50 Coolerado cooler is modular, and the cooling capacity starts at 5 Tons and can be scaled up to 100 Tons.

DOE - The U.S. Department of Energy verified Coolerado has an energy efficiency ratio (EER) of 40.
CEC - California Energy Commission listed Coolerado as an energy efficient appliance.
PG&E - Pacific Gas & Electric’s evaluation concluded that Coolerado qualified for the highest rebate tier.

How Coolerado air conditioners work


The Coolerado air conditioner uses a thermodynamic cycle called the Maisotsenko Cycle (M-Cycle) that capitalizes on natural, clean energy – psychrometric energy – found in our atmosphere. This cycle can improve any energetic or refrigeration cycle.

The patented Coolerado heat and mass exchanger was developed to economically take advantage of the M-Cycle. A heat and mass exchanger (HMX) consists of several plates of a special plastic that is designed to wick water evenly on one side and transfer heat through the other side. The plates are stacked on each other, separated by channel guides.

The purpose of the channel guides is to provide structure to the exchanger as well as direct air movement within the HMX. The channel guides divide the incoming air stream into product air and working air. The product air is always separate from the working air and stays within dry channels the entire length of the exchanger. 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.

Because the heat from the product air is rejected to the working air through heat exchange surfaces in the exchanger, the product air only experiences sensible cooling – cooling without adding humidity. The product air stream is completely separate from the working air and never comes in contact with a wetted surface. This process occurs multiple times in a short physical space within the exchanger, resulting in progressively colder product and working air temperatures.

The HMX system is modular, so the size and shape of a Coolerado air conditioner can be changed to meet user requirements. The Coolerado computer modeling program can be used to design for specific needs. In addition, the product air to working air ratio can be adjusted for a particular application.


What is the cost of a Coolerado air conditioner?
Coolerado equipment cost is comparable to the most energy efficient traditional air conditioners on the market. Find out how lower operating costs, rebates, and potentially lower installation costs can make your Coolerado purchasing decision an easy one.

What are the benefits of Coolerado air conditioners?
Coolerado air conditioners save you a lot of money on your electricity bill, and are healthier for you and the planet. They provide healthier, fresher, cool air without using any chemical refrigerants – such as Freon or other CFCs, and they reduce environmental impact by using one-tenth the electricity of traditional air conditioning units.

How do Coolerado air conditioners reduce environmental impact?
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, so they’re much more efficient than traditional air conditioners during peak cooling periods, 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.

How energy efficient are Coolerado air conditioners?
Coolerado air conditioners use about one-tenth the amount of electricity of a traditional air conditioner.

Do Coolerado air conditioners change the humidity of the cool air they provide?
No. Coolerado only provides sensible cooling (dry bulb temperature drop only … the only cooling that matters to computers), and does not add or remove moisture from the air. Coolerado is capable of temperature drops that are 1.65 times higher than traditional air conditioners. Traditional air conditioners typically achieve a 20°F temperature drop, but in hot dry climates the Coolerado achieves a 33°F temperature drop (110°F & 20%RH).

Can Coolerado air conditioners be used in humid climates?
Coolerado air conditioners can be used in any location. While “high and dry” is the best, 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.

How do Coolerado air conditioners produce cold air?
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.

How much air is needed to cool with a Coolerado air conditioner?
There are several variables that determine how much air is needed. These include the size, activities, desired temperature in the building, the moisture in the outside air, the temperature of the outside air and the altitude. Generally, you need about as much airflow as a traditional air conditioner for the same heat load due to the Coolerado air conditioner’s lower temperatures and no added humidity.

What type of thermostat is needed with Coolerado air conditioners?
Coolerado air conditioners can be controlled with standard heating and air conditioning thermostats.

How often should a Coolerado air conditioner be serviced?
There is a start-up procedure at the beginning of each cooling season that includes removing any winter duct blocking, insuring 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 often depending on the quality of the local water. Air filters need to be replaced monthly to seasonally, depending on the 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.

Will the unit build up with mineral deposits?
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.
