Solar Power Evaporative Coolers

Dependable Solar Products offers a variety of sizes and models of Evaporative Coolers designed for off grid consumer and commercial applications (mainly buildings running on 12, 24, or 48 volt battery banks). These are enhanced, high-efficiency, DC-powered evaporative coolers that use half as much power as regular AC coolers! These units are not typical evaporate coolers in that they do not run on conventional power grid electricity (AC).

WARNING: If your building is already connected to the grid, this system is probably not for you. Instead, we recommend a grid-tie system, which allows the use of solar electricity year round, while also benefitting from utility company rebates.

With utility costs rising and with cooling costs the largest portion of that bill, it becomes more important each year to consider alternatives. The ETA Engineering Solar Powered Evaporative Cooler will cool your home/business for many years for the present cost of one (1) season. 

Compared to air conditioning:

1. Reduces operating costs up to 90%.
2. Produces an environment of fresh, filtered air.
3. Introduces a moderate humidity level.

Compared to traditional evaporative coolers:

1. Reduces operating costs up to 70%.
2. Provides cooler temperatures (5°-10°F).
3. Extends life expectancy.
4. Reduces maintenance time and money.

The solar powered option gives you up to 10 hours/day of “free” cooling when outside temperatures are the hottest and electricity rates are the highest. This "one-time" investment is one of the most cost-effective uses of photovoltaic power, and will return your investment in just a few years.  

We carry two lines of solar-powered evaporative coolers for different applications: 

The Solar Chill^® units are designed for applications with low back pressures, including open spaces, greenhouses, and rooms or buildings where cooled air is brought directly into the structure (such as through a window or a short piece of ductwork) and distributed to other rooms via hallways, transoms, etc. Fans are more energy efficient than "squirrel cage" blowers.  However, due to back pressure limitations, these units are fitted with 6" thick CELdek^® cooling pads versus the 8" and 12" pads on the MasterCool^® units. These units work with grid-tie and off grid power. 

The MasterCool^® units are high efficiency evaporative coolers using "squirrel cage" blowers designed to handle moderate back pressures like in buildings where the cooled air is distributed via ductwork. These units work with off grid power only.  They will also work in applications where the Solar Chill^® units will work but not vice versa. 

Both coolers use the CELdek^® cooling medium, the most efficient evaporative system in production (up to 90%) offering significantly cooler air. CELdek^® offers many benefits including improved comfort, reduced maintenance and extended life span. 

Both coolers offer these advantages:

• Lower cooling costs as much as 90%.
• Remove dust, pollen and pollution.
• DC model (standard) and AC/DC model (special order)
• Available in a variety of system sizes.
• Longer life span and less maintenance.
• Efficient water usage.
