Industrial dehumidifier
« on: July 25, 2019, 05:31:20 PM »
Does anyone know anything about industrial dehumidifiers.  Iím gonna buy one for my wifeís office because she got 3Ē of water down there this week and I need to dry it out.  Iím wondering if anyone has used one in a drying kiln.  After itís done at the office Iím thinking it will be good for my kiln, but not sure.  The one in question is a Drizair LGR 2000.  Iím buying it used.  Itís descrived as low grain.  I donít know what that means.  Thanks in advance.

The weight of water in the air is measured in grains. I assume they are trying to say it gets you down to low moisture.
What the coils are made of is going to be the biggest thing, the moisture in wood is acidic, especially so with some woods like oak. Aluminum coils aren't going to last terribly long in that environment. Nyle offers several different coils at different price points. Ebac makes DH kilns and industrial DH units, the guts are basically the same, the controls are different but it isn't rocket science.

I stand corrected ::). There is another stage before the cooling coils to get the incoming air closer to dew point so that the cooling coils work more efficiently. I read a few company blurbs this one was the best so far;

Do you think your wiwife would notice the difference if you set a Nyle DH unit up in the office for a few days?😁

Thanks for the replies.  Good responses.  I will only be putting air dried wood in the kiln, so I donít feel like the acidic oak is gonna be a big problem at that point.

The thought of a nyle in the office hadnít occurred to me.  The problem is that I already told her I found a dehumidifier for $800.  Iím not sure I can swing the $3000 for the nyle.  Sheís pretty smart.

The troy system historically was used for measuring the weight of drugs, precious metals and gemstones. The name comes from the French city of Troyes. The noble metals (gold, silver and platinum) all use the troy system. A troy ounce is 20 pennyweights. The pennyweight was the weight of a silver penny in medieval England. When pennies were introduced in England in the 8th century, their original weight is believed to have been 24 grains. This was gradually reduced, in at least thirteen stages until it reached 7.27 grains by 1816. 24 grains = 1 pennyweight and 20 pennyweights = 1 ounce troy.
Even more trivia if youíd like to read on. ďGrain is an ancient unit which was originally based on the weight of a grain of wheat. The grain is the smallest unit of weight in the avoirdupois, troy, and apothecaries systems. Surprisingly it is identical in all three systems.Ē 4 grains = 1 carat; 24 grains =1 pennyweight; 480 grains = 1 troy ounce; 15.432 grains = 1 gram.
ďAlthough we have stated above that the grain weighed the same in all three of the above systems, there were at least two different grains. The troy system used the supposed weight of the barley grain, whereas the wheat grain was also used as a standard of weight. There were three barley grains to four wheat grains.Ē

@firefighter ontheside 

The problem with regular dehumidifiers is two things.

1) Corrosion from the tannic acid. You are correct it will be less with air dried wood but it will still be there and cleaning it from the coils will be difficult if not impossible.

2) They only operate at low temperatures and that means very long drying times.

I hope this helps.
