08/08/03: "I just wanted to let you know that the IM-30 worked like a champ throughout the long drive between San Diego and Yosemite National Park (actually Saddlebag Lake, which at 10,200 feet, is above and to the North of Yosemite). It was a lifesaver during the drive through the Mojave Desert. Outside air temperatures were probably on the order of 95-100 degrees Fahrenheit; inside the VW camper, though, we were enjoying an ambient temperature of about 70 degrees. A 70 quart cooler filled with block ice and water lasted us about seven hours; ample time before hitting higher altitudes and cooler temps.
I would recommend the IM-30 to anyone with an older vehicle (its ideal for '60s and '70s VW buses) who doesn't want to retrofit an air conditioning system that might challenge the engine's power output, particularly in extremely hot climates. I doubt a '73 Westfalia such as mine could easily climb the Tioga Pass with a factory-style or retrofit AC system installed. With the IM-30 blowing cool air on the "medium" setting, this was no problem. Thanks again!" D.E., CA.

As the ice begins to melt the rugged submersible pump lifts the icy water and pressures it into the cooling systems evaporative pads. Our first ice air conditioning unit was the Icester which proved the power of this type of cooling, however the cooling ceases once the ice melts. Now you have the option of evaporative cooling alone, like all the other Swampys, or you may utilize the dual cooling system by selecting to use the ice feature and have air conditioning combined with evaporative cooling. A powerful system combining frigid ice water with evaporative cooling adds up to a great alternative to portable air conditioning.

The IM-30 is baffled like the IM-20, T-304, & T154 to keep the water from splashing out when used over rough terrain. The IM-30 evaporative system will cool for two to four hours on one gallon of water. Incorporating the dual cooling system, by adding ice, provides a sizable temperature drop from evaporative cooling alone. If you do not need the cold air ice produces and the humidity is low, you may wish to accelerate the evaporative cooling system by utilizing reusable Freeze Packs. It is so easy to add the Freeze Packs and even your favorite beverage into Your Ice Chest!

How it works: Block or cube ice is placed in the ice chest which chills the water. The water is then pumped into a special chilling core inside the Swampy and also through the evaporative pads. The blower motor draws ambient air through the evaporative pads pre-cooling the air before it is drawn through the chilling core. After the air is cooled it is directed outward to cool the occupants. The water that has been used plus excess humidity in the air and not evaporated during this process is then returned back to the ice chest to complete the cycle.

Our ice models produce a large quantity of Cold Air because they are capable of consuming up to 20 pounds (7.5 kilos) of ice per hour! Ice has a vast energy base and the quicker you melt it the more energy you derive from it in the way of cold air produced. A 48 quart Ice Chest filled with block ice will last around 4 to 5 hours. The largest Ice Chest you can normally purchase is 150 quart. A 48 quart (45.5 liter) size may be purchased in most places like Target for $15.00 +-.

Emptying the excess water from the Ice Chest is a breeze as you remove the return line from your Ice Chest and the secondary pump inside the IceStrMystr itself pumps the water wherever you wish.

One gallon (3.75 liters) of water will last around two to three hours in the daytime and four to five hours during the night when used for evaporative cooling in dry desert climates. The "Ice Water" models are capable of using from 10 pounds (4.5 kilograms) up to 20 pounds (9.0 kilograms) of ice per hour, or more, depending on the ambient temperature and day or night operation.

A 105 Deep Cycle battery, "not being charged", allow the MW1, MW2 to operate for 50 to 80 hours and the "Ice Water" models like the MK3, MK4, MAC & M400 will operate for 25 to 35 hours before the battery needs charging. The Swampy Models will operate about 8 hours before the battery would need charging as they draw more energy.
