It is vital to have the cool air vents within inches of you, not feet away. Take advantage of the cool air with the hose surrounding you for maximum benefit. It is difficult to set the Cooling System within inches of you, therefore the need for the Flex Hose Kit.

Rather than using the Cart battery; it is easy to plug in the 10 Foot Power cord on the MW2 to a convenient $65.00 "Power Station" (Jump Start) 12-Volt Gel Battery with built in charger, that you carry to a rental. These batteries are available at most all Auto parts, Sport stores, Wal-Mart, Target, Costco, Sam's Club, etc.

I wanted to say thanks for your American Made Product and I appreciate your customer service which I think was excellent! I'll be sure to provide word of mouth praise and advertisement for your coolers and your service. There isn't a lot of customer care going on these days so again keep up the good work! C. S.

Air Conditioning provides the Coldest Air in either the Humid or Dry Areas of the World. The Dual System MG4 produces Air Conditioning using Ice with Water or Evaporative Cooling using Water only your choice!

The unit (MG4) I got for the golf cart works great. I have a couple of show cars and my older son has a show car, we go to a lot of car shows, most are during the hot summer months. Sitting under a shade tree is ok, but with no breeze and 105 temp. it can take away from the enjoyment of showing your car. I thought if this (MW1) works anywhere near as well as the unit (MG4) I got for the golf cart life will be better. M. B. Texas

In Dry Desert areas permanently Mounted Roof Top Coolers are typically Evaporative Coolers. The MG4 is designed with Dual Systems providing Evaporative Cooling using Water only, then producing Air Conditioning by adding Ice to the Water. The Ice Water is pumped through a Heat Exchanger in the MG4 producing Air Conditioned air, which also helps combat humidity.

The difference between Evaporative Cooling and Air Conditioning.
In Dry Hot Desert areas Evaporative Cooling occurs when hot dry air passes through a wetted pad producing cool air like an ocean breeze because the water evaporates quickly. In Hot Humid areas evaporation occurs very slowly, so Evaporative Cooling is not nearly as effective and does nothing to reduce humidity, therefore Air Conditioning is preferred as A/C helps reduce humidity along with providing cool air. The Dual System MG4 does it all as you select the cooling method you prefer by using water only or adding ice to the water.

The MG4 uses Ice Energy instead of Battery Energy to provide 'True' Air Conditioned Comfort, therefore your Batteries will not let you down before you finish your rounds. The design as the MG4 looks more like a Hummer than a Corvette as we did not add a superficial aerodynamic frame as we felt it was more important to provide easy installation plus keep the 10 pound weight on the top to a minimum.

Tapping into 12-Volts is simple as the MG4 uses only 3.9 amps (50.4 Watts) so that you can even operate it on an inexpensive 12-volt "Power Station" which comes with a built in charger. Or you may use a Flexible Cigarette Lighter Receptacle that clamps onto 12-volts from your Golf Cart battery pack. Both of these items are typically available at Auto Parts stores, Target, Walmart, K-Mart, etc. All of the batteries may also produce 12 volts with a proper converter available at your favorite service/parts dealer.

The Patriotic Cart with a MG4 on the Top keeping things Cool!

"My brother and I found the installation process quite simple and took less than an hour to complete. The only change we made, was to replace the cigarette lighter end with alligator clips. We found a slim line ice chest that fit perfectly in the basket between the back of the seat and the golf bag rack. The hoses were just the right length to fit our cart. The cooler works great. We are the envy of all our golfing buddies. I feel you will be getting some additional order soon. Sincerely M. B." (Texas).

The 12-Volt 3-speed MG4 uses the same basic system we have shipped all over the World to individuals and governments for use in Vehicles, Boats & Aircraft to reduce Humidity while providing Cold Crisp Air. Swampy Technicians used this same basic system to develop a Dual System Golf Cart Model.

The MG4 rises a mere 7 3/4 " in height above the roof & approximately 4" below the roof. Check out other Specifications

As an example if the ambient temperature on a dry day in the desert were 109 degrees the cool air produced from a well-designed evaporative cooler might be 84+-, however the cool air would be 79+- degrees using the MG4 or MW1 with water only. Under the same circumstances the MG4 would produce 65+- degrees using Ice & Water!

You do not need an enclosure on your Golf Cart to enjoy the cold air produced, although you may if you wish with the MG4. If you are using water only you need some ventilation for Evaporative Cooling.

We furnish all you need except the ice chest, of your choice, that would typically be located behind your seat. Place the pump in the ice chest and plug in the 12-volt cigarette lighter then add a small amount of water and fill with ice, turn the MG4 on & you will feel the cold air in seconds. The water lines to the pump are seven feet long.

All of our Ice Models are capable of using from 15 to 20 pounds of ice per hour during the heat of the day when operating it. We began this project in 1995 and the first models would only use 5 to 10 pounds per hour, which was not adequate. Now enjoy True Air Conditioned comfort with the MightyKool MG4!

The method the MG4 uses to produce cold air is possible because of many thousands of hours of engineering and the Power of Ice when used in a properly designed system. The MG4 may be installed by your favorite Dealer or by providing a 7" square hole in the roof that will easily support the 10-pound weight. A key hole saw may even be used to cut the soft top material and you may wish to go up & review the ideas on Tapping into 12-Volts.
