Product Catalog

Both of our main cooling products - SOLAR CHILLtm and KAR KOOLtm - use a 6 or 8 inch thick fluted type pad as the wet cooling media, it is the most efficient evaporative cooling media in the world, and it should last for FIVE YEARS, WITH MINIMAL MAINTENANCE! (water quality is a factor) The Solar Chilltm coolers are now built of Stainless Steel (all wet parts), and the Kar Kools are sturdy plastic; neither will rust.

New Digital Control Package

Control Package (Now with speed control)

Now cooling your home couldn't be easier with the use of one of our control packages.  This wall mounted control box contains a thermostat, a two speed (HI/LOW)fan switch, a pump switch, and a timer for the cleanout pump.  Set the thermostat and go to sleep without worrying about wasting energy or getting too cold.  Run just the fan at night to conserve energy and water or just the pump for a few minutes to get the pad wet before firing up the cooler.  The cleanout timer runs a pump that will flush out all the water and harmful minerals from your cooler for five minutes which extends the life of the pump, pads, and cooler box.  This is a great add-on to any home cooling system and comes highly recommended by your cooling specialist. Avaliable in all voltages, see price list and specifications for more details.

  • Southwest Solar is introducing a new pump controller for our Solar Chill evaporative coolers. Were offering a new programmable digital pump controller to replace the fixed time cycle timer board that weve used for the last 10 years. There are three main reasons for not running the pump 100% of the time:

  • 1. When the pump goes off, the output air becomes colder.

  • 2. Pumps last longer when pump run time is reduced.

  • 3. Running the pump less saves energy.

  • 4. Your cooler will quieter in general, since it will be off most of the time.

Air Diffusers

This adjustable louver air diffuser is for installation with all the Solar Chill models. Air diffusers are mounted in the house/building and not only provide protection from getting in the fan but helps to move the air to desired locations of the house/building with the horizontal and vertical adjustable louvers.

Solar Chill Pump Control Board

Pump Control Timer Board

One of our newest and best innovations ever, this pump control timer board is an electronic circuit board mounted to the back of the electrical cover plate.  This board can be added to any of our 12, 24 or 48 volt coolers as an upgrade and is now installed standard on all new coolers in all voltages!

What does it do?  The pump board has 2 main functions:  to lower the output air temperature, and to increase the efficiency of the cooler by decreasing the amount of energy used, and increasing the life of the pump by decreasing the duty cycle.

The pump board has a built in timer that turns the pump on for two minutes and off for three.  How does this decrease the temperature of the cooler output air?  Since there is not a steady flow of water passing over the pad at all times the water held in the pad has a chance to get colder than it would if it was flowing over the pad consistantly.  With evaporative cooling as the pad gets colder the output air also gets colder.  The pump board also lowers the amount of energy used since the pump is "on" for less than half the time, and it will as extend the life of the pump.
