    I am considering turning my 4'x3'x2.5' tank into a highland tank. I have been looking around for small AC units for nocturnal cooling. I found this relatively cheap and small portable swamp cooler:

    This would be used in conjunction with a ultrasonic humidifier. Does anyone see any problems with using this cooling unit? Any better options? If this is the case...and I do end up converting my tank, I may have some LARGE neps for sale Thanks for any input,
    David

    Not sure. It says "works great in under 50% humidity"-what does it mean by that? Will it croak in humid conditions?
    I am very intriged, if anybody has any answers.

    Cheers,

    Joe

    Griffin,
    I am pretty sure they mean "it works great under50% humidity" because since it is a swamp cooler and works off of evaporiative cooling the less humidty in the air it sucks in means more heat can be dissipated as evaporated water...if that makes sense. And since I would use it indoors, as I expect anyone would with a terrarium this shouldnt be a problem. My house is usually at most 50% humidity...depending on the season. But it really does look like a great way to cool down a tank, it is small and doesnt use much energy. Anyone else have any input? ow about you Swords? If you are around, you seem to have this type of setup down pat.

    Swamp coolers usually only work in the southwest low-humidity areas because they only cool when the water evaporates. I've yet to hear of any successful installations in the mid-atlantic states.

    If you're planning on using this inside and you have a/c for your house, you will significantly increase the load. Your house a/c will spend some of it's energy removing the excess moisture in the air that your swamp cooler is putting there.

    These are just my quick thoughts and can be / should be over-ruled by anyone w/ direct experience.
    All the best,

    I see what you are saying Ron, however if the swamp cooler had a duct directly into the closed terrarium, the newly moistened/cooled air would be present inside, and not in the rest of the house. And about the humidity, I am speaking for myself when I say that most houses here have dehumidifiers and the humidty inside the house is never above 60%. But thats just us north carolinians. However some like it more moist than others .
    Oh, and the one flaw that I have found with this unit is that it has a relatively small water tank, meaning you would be constantly replenishing it every day...or every other day depending on the amount of cooling. Arrrggg why cant I just have a huge underground basement with perfect humidity and low temps lol

    I live in the south west and swamp coolers are very common... AC is a major bonus!! Not a nessesety (except about 2 months out of the year durring monsoons when the swamp coolers DON'T work) (not really the portable ones... lol) Understand swamp coolers work by air displacment also. AC recirculates your air... Constantly removing the heat. (that's all AC does... removes heat) While with swamp coolers or "evaporative cooler" it takes outside air runs it through pads that are drenched... the water evaporating cools the air.. and in your house, you must have windows and doors open for the old air to go out... I once had window "swamp cooler" that i used when i was an auto tech, i just set it on the bench outside and it directed the cool air on me. I took it to my girlfriends house (now wife) when her cooler was broken and just set it in her room... All this does is HUMIDIFIES!! YES it will humidify your room... unless you have "exhaust" set up on the tank to blow that humid air outside.... It would not make your AC work harder to remove the water... Because your AC doesn't run to "remove humidity" it is a by product. BUT you're house will feel warmer because of the humidity content. Also, the temp drop through evap cooling is not that great... Exp at already cool temps. You can expect 8-28 degree drop depending on pretemperaure/humidity level etc...
    Bottom line, I would say it WILL NOT work in a terrerium without lots of work... And I'm not sure you can get a big enough temp drop for it to be a highlander tank....
    Hope that helps
    Andrew

    Additional information from wikpedia...

    "Performance

    Understanding evaporative cooling performance requires an understanding of psychrometrics. Evaporative cooling performance is dynamic due to changes in external temperature and humidity level. Under typical operating conditions, an evaporative cooler will nearly always deliver air cooler than 80 Fahrenheit (27 Celsius). A typical residential swamp cooler in good working order should cool air to within 6F - 8F (3C - 4C) of the wet bulb temperature.

    Some rough examples clarify this relationship.

    * At 90 F (32 C) and 15% relative humidity, air may be cooled to nearly 60 F (16 C).
    * At 90 F (32 C) and 50% relative humidity, air may be cooled to about 75 F (24 C).
    * At 105 F (40 C) and 15% relative humidity, air may be cooled to nearly 70 (21 C).

    Because swamp coolers perform best in dry conditions, they are widely used and most effective in arid, desert regions such as the southwestern USA and northern Mexico."

    "wet bulb" is refering to the coolest temperature the air can be cooled by a evaporative cooling....

    awesome, thanks for all that info andrew, it was very helpful indeed! So I will get rid of that idea. I knew that little evaporative cooler was too good to be true . Basically I want some type of air conditioner that is relatively cheap that I can hook up to the terrarium with a humidifier as well. I would like not to have to get a window unit, but thats all I can find. Oh well, back to the drawing board.
    Thanks all for your insight
