How Coolerado Works

How Coolerado Works


It’s a whole new way to cool using indirect evaporative cooling technology. Instead of using chemical refrigerants and compressors to cool recycled interior air, we use a new, patented process that runs fresh outside air through air filters and then a heat mass exchanger (HMX). This unique process delivers more comfortable, breathable air using one-tenth of the energy of typical air conditioners. Even Dad would be impressed.


They told us it was impossible. But, we proved them wrong. Some of the best minds in the industry told us we couldn’t build an air conditioner that uses up to 80% less energy* and without using chemical coolants. But, we did. In the process we also dramatically improved our customers’ air quality and reduced their carbon footprint.

The patented Coolerado heat and mass exchanger (HMX) was developed to take advantage of the M-Cycle economically. A heat and mass exchanger 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 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. The heat is exhausted out the sides of the HMX and then to the atmosphere.

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.

*80% less energy is based on Coolerado products when compared to compressor-based cooling technologies, intended to cool an equivalent amount of square footage. Typical energy savings results will vary based on application type, heat load and climate and range from 50% to 80%.
