commercial dehumidifier

[PoopyTeaBags]

hey guys i dont know much about dehumidifiers but these regular ones are just not cutting it...

Anyone know of dehumidifier that not 1k that works... im running a 6k coco run and humidity is bad... also wondering if they have exhuast so you can vent them out the room?/

thanks for any help...

Dehueys pretty much never have exhausts, they collect water into a tank or let you connect a hose to drain them. Check out Dri-Eze, I see companies selling used ones on Craigslist for $500-1000 (they are 3-5 times that new) or of course there's the Santa Fe ones from Sylvania. You probably need something in the 75-100 pints per day range, or bigger.

Do you run an AC? That will work as an additional de-humidifier. The AC will also help to counter the heat from your dedicated dehumidifier.

i run a a/c and deumidifier and im still at like 60% give or take 5% its very hot i may have to rerun my intake lines im not really sure going over cost atm...

look at a retail $200 unit and see how it is actually rated. An LG/GE etc rated at 65 pints is NOT the same as a Santa FE. Saturation rates, ASTM testing standards all come into play.

Plus the bigger units use the same or just a bit more electric than a retail unit. Use 3 retail units and you electrical useage goes up.

I talked to Santa Fe and there is no way to vent the heat. The hot air is the dry air.

I run my 6k room with a 25,000BTU AC in a custom box, and a 50 pt dehuey. I can keep RH at 30% indefinitely, if I so please. This is underground, so the outside ambient plays little role.

my a/c is half your size... i would be good if my a/c was 25k btu.. hehe can only wish...

Theres a guy who sells brand new 80 pint woods on ebay for less than $500 shipped, there retail over $1000- Work nice. I got it and 2 day later my 70 pint top of the line sears model started leaking lol I knew that plastic piece of crap wouldnt last 1 round.

That is correct. You need to compare ratings from apples to apples, not organic orchard apples to machined aluminum-alloy aircraft wing parts. Many "commercial" units will list their AHAM ratings, which is 60% RH @ 80F. Most "consumer" units, as well as many "commercial" units (including many Dri-Eaz models) will list the performance at a much more favorable condition typically near saturation.

To give you a real-world example of how these numbers might come into play, take a Santa Fe Classic 100ppd vs. a Kenmore 70ppd. In my experience, the Santa Fe Classic easily removed nearly as much water as three (3) Kenmore 70ppd's (that's 210ppd, supposedly)... and draws about the same amount of power as one (1) Kenmore unit. There are even more efficient units as well. When you're running so many consumer units, you'll obviously throwing a lot of extra heat in the room as well. If your A/C is over-sized that much, it could help in that the extra heat will cause your A/C system to cycle more often, adding more dehumidification naturally.

There are other technologies and features that will improve "between the lines" performance, such as hot gas defrost systems (instead of timed/timed auto sensor) in certain conditions. So even at the listed "AHAM ratings", it's not exactly apples to apples technically, although in most growroom environments it is typically the case.

I talked to Santa Fe and there is no way to vent the heat. The hot air is the dry air.

It's not possible out of the box, but if you understand HVAC basics you don't even need to ask this question and will know that it's possible with modifications.

And by the way, Dri-Eaz (yes, the entire product line) sucks in comparison to others available. (It's over-priced & under-performing.)

No, it's not good.

In fact, I'd say it's "terrible", for $500.

You're growing 6kw (for profit) that's probably going to earn you at least a decent living. Don't complain about having to spend $1400 (small bones) on equipment that's going to satisfy one of the most critical components of your environment.

By the way, "Sylvania" doesn't make any dehumidifiers, and neither does Sylvane. (Sylvane is just one of hundreds of distributors / resellers.) ThermaStor is the company that makes both the Santa Fe and Phoenix line of dehumidifiers.

Getting RH down to good levels is way underrated amongst many growrooms I've seen. Dehumidifiers are most often skimped on.

Ahh the monkey style is back!

Upgrade your AC first. You can get them used on craigs list for dirt cheap before the winter, depending where you live. I got my 25,000 for $200.

Did you figure it out yet? Those Dri-Eaz units on craigslist are generally not a good deal. In fact, the entire Dri-Eaz line isn't very effective dollar-for-dollar compared to other brands/models.

I personally have a lot of faith in the ThermaStor-made brands (Phoenix, Santa Fe). You can sometimes find used ones for a good deal, and the rating is always the AHAM number. Dri-Eaz often tries to confuse you with different numbers, and many of their lower-end "restoration" units don't have intercoolers.

They're built incredibly well, too.
