Tired of the incessant rains and the high humidity levels in my place. Its so high that I'm seeing mold growing on back of wooden cabinets and on places where its dusty - like wires behind my comp desk. The dust on the wires become moist due to humidity in air and mold grows on them. I'm really tired of this stupid humid climate. :@

Want to know if there are room dehumidifiers available here or should I be getting them from usa like amazon?
I found a good one thru google and some sites. I didn't find home use appliances from Indian manufacturers though.
Anyone having knowledge of these appliances?

^ nice link. was searching a Indian manufactured ones and saw another company too.

Dehumidifier Manufacturer India, Supplier Dehumidifier India

But, I'm not going to buy the ones that use compressors. dehumidifiers are supposed to be kept on for atleast 6-8 hrs per day and the ones with a compressor in them will use atleast 250w/hr of electricity. besides, i think in summer if i use a dehumidifier, the temps will go down too, since it will become less humid. the link i gave above has one with peltier tech in it and uses just 70w. wonder if the shipping weight will kill the deal. sent a quote to icc. lets see what turns out.
 
Er...I don't know if this is appropriate but I manufacture de-humidifiers. We even have a patented design. Send me a pm, I'll try and see if I can offer a solution.

Reading one of the reviews in your link and it states 230-250ml of water removed in 24 hours.

If you need to draw more than that then shipping weight is the last thing to be concerned about.

And these pull in several litres/day or a factor of 5 to 10 more.

First problem you need to solve is how much you need to pull from the air so as to better size the unit to your requirement ?

Any idea :)
 
^ no idea actually. 1-2 liters per hr (or day?) would it suffice or would it be less? first time i'm buying such a thing so don't know about this. i only know that i need to bring down the humidity level down in my bedroom. smells musty when i switch on the fan. :(

those reviews are wrt to the environment there. dunno how that apparatus will perform here. humidity levels there and here are quite different imo. so if it removes 250ml there, it could very well remove a liter or two (or more) in the same time frame here. can't say for sure though unless someone is actually using that appliance here.

i don't want an industrial size one which will remove moisture drastically from air in an hour or two. Those things are very expensive and very heavy and i want something portable which can be moved around from room to room when required.

It's per day and I think you should spend more time researching this aspect before talking to any salesmen ;)

Once you know what your reqs are you can better assess the value of any offering.

And that would indeed be a miracle because somehow the laws of physics do not hold in your place.

If that's what it does there you can be sure it will do close to the same for you.

The person was talking about a 900sqft place and moving it from room to room.

And i'm under the impression the ones here that do upto 5 times as much as the one you linked are portable, they just take up more space, and are more noisy. To me that's stil better than shelling out loads from something from abroad that is all nice & quiet but does not entirely get the job done.
 
ok after a lot of reading articles here and there, i found out that ambient room humidity would be around 45-50%. For an area of my room with 125sqft space (1250 cubic cc), i need to remove about 8 liters of water from the air per day to get to that level (if i take humidity level to be around the 80% mark) i think.

See link below.

AHAM - Association of Home Appliance Manufacturers

Also @blr_p, the EVA-Dry is rated for removing around max 600ml of water at 80%rh and 80deg F, for 2200cc air volume which approximates to around 220sqft room.

I plan to use it im rooms that are no larger than 150sqft. only minus point is its removing less than required water from air.

edit1: got quote from one of the companies. for my requirement, there are two models - one at 13k and other at 15k. The 15k one takes just 180w/hr - emptying 12 litres/day compared to the 13k one which uses 220w/hr - emptying 10 litres/day.

totally out of my budget of 6k for these things. :(

edit2: got quote of 6936 with ebay link for the eva-dry 2200 from iccworld. seems like not worth it for the amount i think.

HEy...

Im not sure but I think Air Conditioners have humidity control option in them..

Or you could try using Those SILICA CRYSTAL that come in the boxes of electronic equipment..

So you could try placing those crystals inside your cabby and close to other electronic items and around those wires.. If possible see if it works and share it here..

I'm thinking try before you buy.

See whether you can rent out anything for a month or so to get better idea of what you need.
 
sorry to bump this up, but need to know where I could get a good very accurate (+ - 1% accuracy or more) hygrometer. I've seen some Honeywell brand and Western Caliber brand on amazon and also some cheap chinese stuff on ebay india. but the cheap ones are + - 8-10% off. I dont mind getting one of these since they are extremely cheap but problem would be how to test accuracy of these chinese stuff.
