I am looking for REAL WORLD experience from those that have used commercial dehumidifiers. These are the refrigerated models that use low grain refrigerant to quickly get rid of allot of moisture at realtively low amperages.

Looking at the dri eaze 2800I .... http://www.drieaz.com/_DEC/DEC_Product_Base.aspx?decID=1138

Which is pretty money 130 pints at only 8 amps!

Or some kind of orian brand.. http://www.ebacusa.com/orion.htm

All I know is the $250 home depot dehumidifier that runs at 6 amps amps pumps shit loads of heat into the room isn't doing it.

Any advice is greatly appreciated.

I had one in my dining room after my upstairs neighbor decided to flood his kitchen. They still push out a fairly decent amount of heat. You have to exhaust the heat when you have a machine that does work. There's going to be heat generated when cooling the system.

Hey LF,

Currently I'm using the Ideal Air 100 pint/day dehumidifier in conjunction with a $250 home depot special, which like you said helps but just doesn't do the trick alone. What kind of setup do you have? Number and wattage of HID lights, grow space, number of plants and the size of pots you use, plus how many gallons of water you use on each how many times a week? For instance last spring i was using 12 3 gallon pots, watering each about 5 gallons per week. Now I'm using 15 gallon pots and each needs about 10 gallons per week...lots more moisture in the air nowadays. If you don't mind me asking, where are you? I live in the Northwest and we have considerable moisture in the air year round, which also increased my dehumidifying needs.

How are your grow conditions? I've found that increasing room temps ten degrees doubles the amount of moisture my dehumidifiers remove...but it also increases the room's humidity. If you're already running at 80 degrees+ already this wouldn't be an option.

You wanted advice from experience, and the experience I've had with every dehumidifier I've ever owned is that they never remove what they advertise. My ideal air 100 pint removes about 50 pints a day--I think this is pretty standard. The test conditions they use for ratings are NOT what you would want your room to be like! First find out how many gallons you put in your room, assume your plants use about 75% of it, then get the dehumidifier(s) that will remove double what you need them to. That's what I've had to do and it's worked beautifully so far. Just bite the bullet and get the one you need..

It seems that the "real" dehumidifiers are rated at 80 degrees and 70% humidity. The cheap ones solld in HD and what not are rated at "absolute humidity" which is 100% humidity. In real world conditions, they remove water at a rate that is about 1/2 of their listed rates. That and they are incredibly inefficient at doing so. Professional models remove at 2x-3x the rates at the same electrical draw.

I'm looking at getting a craw space unit, this one http://www.dehumidifierexperts.com/product.php?p=thermastor_4025699&product=112831

90 true pints a day and a air filter that will take out mold spores..
