Whats the big appeal to a quest overhead unit i currently use 2 50 pint ground units that drain to a storage bin I would consider upgrading to an industrial unit but what makes it so good if it has a similar pint per day?

Efficiency is what youre paying for.....I had two 50 pint dehumidifiers but I bought the 110 model when I realized I was using double the wattage.

Floor space and efficiency

Amp draw is the biggest reason I see to get one, and also just for the power they deliver. I use a 70 pint and a 50 pint and barely keep up. So really I'd need 3 household units.

Theyre cool and all but overpriced. I got 2 95 pint dehumids for $350 each. Theyve been working perfectly so far for the last year.

for a 205 quest dehumi...I gotta cough up at least $3k? To save like 300w of power compared to running 2 95 dehumis? If I have a few extra grand to spare..... Id maybe consider it if my floor space was limited.

Not the pint per day rating rather the efficacy rating (IEF Liters/kWh) not noly that but the quests are filtered much better then your typical residential grade honeywell 50pint per day dehumi. They are very pricey units but they are top of the line and worth the investment. You wont spend the same amount of time and energy maintaining the quest as you would with the other dehumi's because of the filtration and you will use about 1/2 to 3/4 power to remove what the other 2 units do because it will take half the time for that to remove the moisture from your room and has twice the IEF rating, and you can hang it on the ceiling which is nice for floor space, as ren said quest understands and designs for our industries needs and its built with quality materials that will stand up to the normal wear and tear much better then a residential unit would... unless you dont have it to spend id get the quest and never look at another residential unit again. One more thing is those quests were designed to run constantly and will without over working the unit where as your residentail equipment was designed only to run intermittently throughout the day. Quest was made to work the residentail ones wont handle the same work load over time and will need to be replaced and serviced much more often.

This is one of the toughest things to figure out Ren, till you waste enough money trying to save some that is lol
I learned this back when I first started growing, quickly realizing there is no "budget" gear that will compete with higher quality products. I did regress a bit when I setup this grow and I figured saving 3k per AC unit was a smart idea. Well it wasn't and I wish I had went with Mitsubishi over Midea. lol

I just purchased a Quest Dual 155. It's one of the most efficient dehumidifiers on the market; with the Dual 105 being tops. In my previous rooms with four 1000w DE's, I used a non-commercial 80 pint dehu. However, it would only ever fill a 5 gallon bucket in 24 hours which is half of its stated daily capacity; or 40 pints. It also didn't bring the humidity as low as I would've liked. It also wasn't a completely sealed room; window AC. It was constantly struggling, and I think it used more amps then the new 155. Now, I have a 12 light room. We'll see if how the 155 works and whether I bought a big enough Quest. I mean, obviously the Quest is going to work better and be significantly more efficient. Being able to hang it up high/close to the ceiling should help as well as dehu's work better with hotter air. It will also keep the dehu heat up high without hot air blowing around on the floor and at base of the plants;(of course it still heats the room. The room is 34 x 10. Once we hit two to three weeks of flowering, the room will be getting about 75 to 80 gallons of water every other day. The normal humidity in these rooms prior to adding plants is 40 to 45%. They'll be sealed rooms with exhaust only coming on just before and just after the lights go on an off. It may take me about 8 weeks to get to that stage to report back to this thread, but this will be a good resource/evaluation for anyone looking to buy one in the future. Let's hope I bought a big enough Quest. Better yet, let's hope it's so efficient I can downsize next time. :)

Gardenator, you have some experience. Do you think the 155 might work? Thx

I went to the shop and placed an order for a 70 pint Quest dehumi today since I had some extra cheese from last harvest.

Im going to put it in my veg and see how it does. Right now I have a Cooper and Hunter 70 pint dehumidifier and it does a pretty good job. My only problem is the humidity fluctuates like 20-25%.
It was $250.

The Quest 70 pinter I ordered is $1000. Im hoping it makes it so my humidity fluctuates like 5% instead of 20% for 4x the price. Theyre both about the same wattage so Im not going to be saving much power over time.

My logic at this point in time is this. Theyre both 70 pinters. Sure...quest you can hang and have a little more walking space and its a little more efficient collecting hot air at the top. But at the end of the day theyre both 70 pinters. Is it really 4x the efficiency just because you can hang it?

But I am open to see the hype. Hence the order. I hope its really as good as people say and I eat my words. I dont cheap out on anything besides dehumidifiers honestly because a pint is a pint.

Okay so i would have recommended the quest dual 225 for that big a space and 12 lights. One because the price differential between the two is minimal and Two because i have a 14x10 and a 16x16ish both 6 light rooms, the bigger of the two is lit with 1000w de's and the other is lit by 6 800w led fixtures (the sunplix 8 bar fixtures) led room houses around 80 plants give or take and the second room is a bit bigger but plant count is down about 25-30% because they get much bigger, 2 ton minisplit for the de's and a 1 ton for the led room, i have a quest dual 225 for these two spaces (basically the equivilent of your space roughly) and this is the one you will want. I am subbed and looking forward to that 8 week report back on the dual 155, it should work but i believe that efficency wise you will want to upgrade to the bigger unit as its not going to work as hard or draw as much power, in the end it will be saving you some bucks in over head costs

Check some local hydro shops for a used one I got a quest 105 years ago when it was the most effecient one for $800. They said it was only used for 1 grow alot of people fail at growing haha. I hung that big ass dehumidifier above plants in a 4x8 tent it's made for over 3000sf but used less power than the floor dehumidifier I would have needed and I wanted to use my limited power on lights. They work better all around more reliable more effecient more accurate and it moves alot of air so helps airflow.

Thanks for the info. You may very well be correct that I need the 225. We shall see. I see your point about on overworking and cost. Desired VPD will play a role. I have a Carrier 3.5 ton backed up by another 3.5 ton. Only one should be running AC at a time with one set 3 degrees higher than the other, but both will always have the fans running to circulate air. I'll let you know how it goes.

That 185 Cool is expensive but interesting.
Cheers
edit: I can't use the 225 or Dual 165 as that dehu specific outlet was wired for 110v. So, I better hope the 155 is good enough. *crosses fingers*

Older thread but bearings are biggest difference. They’ll outlast all your none industrial/commercial dehumidifiers and are designed to run 24/7. Your cheap ones are not designed to run every second of everyday, like Quests and Andens are. Plus they’re are WAY more efficient, with WAY better filtration!

Ive worked in grow spots running home dehumidifiers. they last a long time. maybe the odd one takes a shit once in a blue moon. Both the home dehumidifiers and Anden/quests are rated per pint for 80F/60RH so the pints are similar.

I just ordered another Anden for my veg. I like them only cause I can just hookup a controller to it and put it at canopy level to dehumidify instead of getting the humidity % at the ground. Also hanging them to save floor space is a big thing for me too since my rooms are crammed.
