G'day,
Earlier I mentioned that my Cousin in Grand Junction, CO had a swamp cooler on the roof of his home. When we visited in the summer
of 2002 it was cool but it felt clammy and there was a slight smell too.
This unit interests me as in the Outback it is SERIOUSLY hot and dry. It might be a good second unit, one A/C and one TurboKool
unit. However, I am concerned with mold developing so I sent the email below to TurboKool:
Hi,
I am interested in your TurboKool units, I see that you do not recommend them for areas where the relative humidity is greater than
75%. Do you have any information which shows what the relative humidity inside the RV is raised to when it is running?
I assume that the ambient outside air temperature and relative humidity will have an affect on that.
Thank you,
Rob M.

They use different types of pads in swamp coolers. From Spanish Moss, and beyond. Some pads retain water forever and smell more musty then others. The TurboKool is a mobile unit and doesn't use the excelcier (can't remember how to spell it) type pads. Swamp coolers should be maintained. While they work well sometimes with little to no maintenance they work best and smell the least with cleaning. My in laws until recent have only ever used swamp cooling to cool their home. My father in law is good about keeping the unit clean. While they have a slight oder its not a bad smell at all.
This will be my first unit ever that I owned that was made for mobile use. I've heard many times that the small mobile units (not TurboKool) are useless. I'd agree based on home use. A swamp cooler thats small used in a home is useless. But a large cooler, can easily cool a home. My wifes aunt uses a swamp cooler on a brand new home (they also have AZ of course) about 90% of the summer the swamp cooler keeps the house so cold it will freeze you out. Living in the dry we do, I personally love the swamp cooler. It keeps the air more moist. The super dry air we get all year is nice to get a little humidity. Many parts of the world swamp coolers of the right size can be used.

Some of you may recall that I rebuilt a horse farm estate about 4 years ago. This home had 2 AC units and a giant swamp cooler. The swamp cooler worked gret for about 9 months in the AZ climate without any smells or clammy feel. it did require a totally different regiment however. You had to open the windows and get a lot of cross ventilation going. I'm still very interested for my coach. When the humidity is up here you don't need cooling.

Bob- I was thinking that a swamp cooler would work great when we head to the rim or payson. Just sometimes maybe for 2 hrs a day or so it just gets warm enough inside the coach for a little cooling. Or even on some of our cooler days it would help on low. Friday I was working most of the day in the coach and while it was only 70 something outside working inside was pretty stuffy. Our winters are really dry here. My coach dash AC doesn't work. I was going to fix it but why suck up all that gas. If the Turbokool works then I may either add another depending on how well it works, or buy a AC to drive around with. The reason I don't like option B is I really don't like the idea of having to keep my onan. I want to go 90% solar.

Rob,
I installed a mobil unit in my shop for use on those days when it was over
100 deg. Within three days, surface rust started showing up on all of the
exposed metal in my shop, which, as you know, is a lot. God rid of the
thing and went back a fan. Next time you're in swamp cooler country, look
at what those things do to roofs.

Way back in 1953, I was one of some 70 or so Boy Scouts
in western NY (Chautauqua County) who made an auto trip
lasting almost a month to the World Scout Jamboree at
the Irvine Ranch near Santa Ana, CA.
Needless to say, the heat became a problem. In those days,
there were torpedo-shaped devices that you would hang
over the pane of a closed window. This device had a water
reservoir of some sort through which outside "ram" air
passed, was evaporatively cooled, and then routed to the
interior of the auto.
I'm not sure how well they worked, but even a little was
helpful to the occupants from an area where the high
temp for a year MIGHT reach 90F!
We also hung what I think were called "desert water bags"
on the front bumper guards. These were slightly porous
material that were soaked on the outside and once again,
air being forced over them cooled the contents somewhat.

A dripping, unmaintained swamp cooler will ruin a roof for sure. But if it doesn't drip it can't ruin a roof. The only thing it does is suck air through the pads. A working cooler doesn't cause any roof damage. I do not agree that it will rust things. If the air is 5-25% humidity in AZ and the swamp cooler adds to that its still less moisture in the air then most places on the east coast in the summer. So yes, I guess because we live in a ultra dry climate that nothing ever rusts perhaps adding humidity would assist in the rust process. Only based on we go from little to no humidity to adding some. However we'd still have less humidity then 2/3 the USA in the summer. If swamp coolers added rust the entire east coast would be a rust bucket. Many cars there rust not because of humidity but because of the salt they put on the roads. I've been to many older homes here in our part of the state and have never seen things rusting cause of the swamp cooler. My wife has a aunt that lives in a brand new 2 story home with a large cooler on the roof of their porch which is the same height as their bedroom window. They mounted it on wood it make it the exact height as the window. It cools the entire home most of the year.
Alls a swamp cooler is for a home is a box. Sucks air in thru most pads then blows the moist air out. A dripping unmaintained swamp cooler can cause all kinds of damage. Just as a dripping unmaintained car, bucket of oil, fan, broken wood, but a maintained cooler works well.
About the smell. I've walked into a lot of homes that smell, and they don't have a swamp cooler!

The low-riders car guys around here like the car coolers.
I rebuilt one and used it for a short time.
Works, but is noisy.
It you find one pick it and make quick buck on eBay or Craislist.

Has anyone that has commented about coolers ever used a TURBOKOOL on their RV?
This is a honest question, are your thoughts just based on home coolers, and other type of coolers used in mobile applications?

Keep in mind that our rooftop AC units are 100% recirculated air.
A swamp cooler will be 100% outside air being brought in. That said, you create positive pressure (a good thing for tank odors etc) but you need an equal/opposite path for the air to exit IE an open window or maybe better a Fantastic fan up high to let heat out. If the coach is buttoned up tight as when trying to cool with freon AC, the airflow will be restricted other than what can leak out through say the range vent and out the sloppy seals by the refigerator venting, back out throught the dash AC system etc. Not knowing the CFM of the unit I would think for the cooler to be effective it would have to change out all the volume of the coach each minuite as the are is cooled but not cold. That's not a bad thing and I would think would be good for sleeping with all that fresh air coming in. I don't know if these can be modified with a drain so that some of the water is spilled off as the float replenishes, like some humidifiers that have a flow thru drain. This would provide, to a degree, a self cleaning effect and slow mineral and mold buildup as the water is always being freshened. Wonder if that drain could be turned off when camping w/o a hookup? Just thinking out loud here. If say the rear AC was swapped for one of these that would have to be a weight savings too.

Opening a window is a must! My GMC leaks more air then a outdoor flea market, but I'll open up the vent for sure. I was thinking of the weight savings as well. I think it weighs 14 lbs, of course without water. Since I'll be going with 6 solar panels any weight I can shave will be helpful.
A drain maybe a really good idea. Mineral buildup is a serious subject. We have tons of calcium in our water here. I think having a drain would be a good idea as well. Since they don't use much water run off would be a minimum. But mineral is my main concern. I'm guessing since it will not be used often it won't be hard to clean. But draining a little would be nice.

No mention has been made of it in this thread but there are swamp coolers that do not put moisture into the air or that are designed to put a lesser amount of humidity into the air.
Obviously the indirect or two stage coolers cost more than the direct cooler.
Direct evaporative cooling (open circuit) is used to lower the temperature of air by using latent heat of evaporation, changing liquid water to water vapor. In this process, the energy in the air does not change. Warm dry air is changed to cool moist air. The heat of the outside air is used to evaporate water.
Indirect evaporative cooling (closed circuit) is similar to direct evaporative cooling, but uses some type of heat exchanger. The cooled moist air never comes in direct contact with the conditioned environment.
Two-stage evaporative cooling, or indirect-direct. Traditional evaporative coolers use only a fraction of the energy of vapor-compression or absorption air conditioning systems. Unfortunately, except in very dry climates they increase humidity to a level that makes occupants uncomfortable. Two-stage evaporative coolers do not produce humidity levels as high as that produced by traditional single-stage evaporative coolers.
In the first stage of a two-stage cooler, warm air is pre-cooled indirectly without adding humidity (by passing inside a heat exchanger that is cooled by evaporation on the outside). In the direct stage, the pre-cooled air passes through a water-soaked pad and picks up humidity as it cools. Since the air supply is pre-cooled in the first stage, less humidity is needed in the direct stage to reach the desired cooling temperatures. The result, according to manufacturers, is cooler air with a relative humidity between 50 and 70 percent, depending on the climate, compared to a traditional system that produces about 70–80 percent relative humidity air.

I would guess a two-stage cooler uses more electricity than a single stage, but less than a compressor type A/C unit?

In the direct stage, the pre-cooled air passes through a water-soaked pad and picks up humidity as it cools. Since the air supply is pre-cooled in the first stage, less humidity is needed in the direct stage to reach the desired cooling temperatures. The result, according to manufacturers, is cooler air with a relative humidity between 50 and 70 percent, depending on the climate, compared to a traditional system that produces about 70–80 percent relative humidity air.

That is correct. A two stage would have an additional pump to pump the internal liquid through the heat exchanger. However this would be a lot less electricity than the compressor in an air conditioner would use.

Above 75%, swamp cooler still! lol When we camp in the summer we are always about 6,000 to 10,000 feet high in elevation. Up there is usually a ton cooler. Right now we have nothing to cool us (no AC) and haven't died yet (even though we have often felt like it!) Before I insulated the front floor board it was so hot you wanted to die in the summer. But then we'd get to the mountains and it would be fine. I solved that issue. I'll have to judge if I need two of the TurboKools maybe needed when driving, or just give in and buy a TurboKool for the mountains and buy a AC just when driving. There is no doubt in my mind a 15,000 BTU AC would work better. But my goal is to get rid of the Onan and go solar (with a small portable generator). The only bonus to the Onan is its got 78 hrs on it, its from 2001. And you can't smell it when driving. So if all doesn't work I'll put a 15,000 btu up front and the TurboKool in the back.

Michael,
From what you write below it appears that your primary use for your GMC is to dry camp at elevation during the summer months.
To do so you are equipping your GMC with solar panels and a small generator.
Since it not feasible to run a vapor cycle roof air off solar panels and batteries you will install an evaporative cooler.
Since you don't have any A/C now you are willing to accept whatever cooling the evaporative cooler will provide whatever the
relative humidity.
That's is a fine plan, however, do you think that removing a vapor cycle air conditioner and installing a evaporative cooler is a
good idea for folks that want to tour the southeast USA (or anyplace where the relative humidity is above 75%) during the summer
months?
Regards,
Rob M.
