Hey camper, as far as the swamp cooler do I need to be concerned about all the moisture they put out in relation to any electronics or specific materials I put into the van?
Greetings!
These coolers do not put any moisture into the air at all. Unlike an evaporative cooler, this system is sealed, the cold liquid is circulated through a car heater core or transmission cooler core.
Up to about the mid 90°'s I run mine with just plain water, then if needed I'll add a block of ice, which will last the better part of a week. Above 120°, I'll drain the system and switch over to 2 gallons of antifreeze and get a big block of dry ice, now you have to be careful with it, and keep all but the top side wrapped in plastic, because it can't come into physical contact with the antifreeze. The dry ice will last the better part of a week too. It's kinda spendy, about $25 for a 50 pound block, but your cooler will be blowing air so cold you won't be able to sit in front of it without getting frostbite. At 130° in Death Valley, even with the fan set on low, I wound up opening a window because it was getting too cold inside, and finally I put on a sweater. So it DOES work, sometimes too good, especially if you put dry ice into it.
Just holler and I can give you specific directions on how to build one. In fact may I should start a new thread about how to build them.
Cheers!
