Autofilling Humi for Walk In
I'm completely ignorant to the logistics of large scale cigar storage - but my overwhelming can-do attitude and addictive personality are driving me into building a walk-in humidor.
Fortunately, I know a gent who is knowledgeable on the wood/sealant side of this. Unfortunately, I'm not sure where to turn for humidification. Here is the thought: Right above the room that would be converted to a humi runs the cold and hot water lines. I figure I can put some type of split line on the cold water line - maybe a hose bib or similar... This line could then be managed with some type of control that adds water to an active humi system as required. I'm not sure what type of humi or equipment I would need - and searching through old posts didn't find me anything (although I may have missed it - feel free to point me to the appropriate link). So - has anyone done this or know how? I could do one unit with the water line feeding it, or daisy chain two but I think that might be overkill. The space is 5'x6'x10'. |

Re: Autofilling Humi for Walk In
About half the B&M's around here are using these Trion 707U auto-filling humidifiers:
http://www.filtersfast.com/Trion-Her...07U-Filter.asp BUT, unless you are going to run that water through a purifier, preferably DI or a distiller, a good RO system in a pinch (not all RO units are created equal), first, it's probably not a good idea. Last edited by T.G; 06-05-2010 at 02:19 AM. |

Re: Autofilling Humi for Walk In
I'd say unless the humi is going to be 100 sq feet or more you probably won't need an auto-fill option, unless you plan to be away from it for extended periods. I'm not really familiar with the humidifiers used in walk-ins, but if you really do want to go an auto-fill route, you should probably still use distilled water. Tap water will leave a mineral buildup over time as water cycles through it.
A quick search on walk in humidifiers turned up this one: Link Not sure what your budget looks like but that Humidifier isn't all that much more expensive than just buying a couple hydras for a cabinet. It does have an auto-fill feature, which you could hook up to a home distiller unit like like this one. It has a dispenser pump option that would in effect be the same thing as tapping into a water line. My father-in-law sells distillers (owns that website), so I could talk your ear off about those all day long. I personally have this one in my house right now. It's actually hooked up to an auto-fill setup for a Hydroponic Garden I have going. We also use it for normal drinking water. The tap water here in Reno is horrid, and if you knew half the stuff I know about what is in tap water (and even bottled water) you'd probably never touch the stuff again. Even RO isn't all that great in comparison to distilled. Can't beat zero contaminants. Anyway, if I was going to do it (and I'm sure I'll get there eventually), that would be the route I take. -Chris |

Re: Autofilling Humi for Walk In
Looks like T.G beat me to the humidifier link. The site he posted is actually $100 cheaper than the one I put up. Can't really beat that Cubic Foot support for only $230.
Distillers aren't cheap though, as an FYI. I've never really shopped around other than the ones my FiL sells, but even the smallest ones will set you back a few hundred dollars, and one that can do 10 gallons a day will probably start around $1500. You might be able to find one that can do around a gallon a day (can't see the humidifier using more than that) for around $500. Just make sure it can hook up to a pump for the auto-feed. |

Re: Autofilling Humi for Walk In
interesting, thanks. I did not initially think about the distilled aspect, even though distilled is what I use in my vino now.
appreciate the links |

Re: Autofilling Humi for Walk In
I missed that part when I responded last night. That's only 300sq ft, don't even think about one of those Trion 707U's , they'll turn the place into a swamp within minutes. Not to mention that you'd have to modify them to a lower fan speed or whatever wall is opposite the unit will end up soaked. When they kick in, they visibly blow cold steam 10'
Not sure if you're going to find a small auto-fill humidifier. You could probably modify just about any humidifier tank with a level/float switch tied to a relay that operates a solenoid valve on the water line though. |

I missed the size too - much smaller than I was thinking when you say walk-in, Still looking at a lot of $ in materials for something that functions correctly and is reliable. |

I took a look at the humidifier units last Saturday, Meh. Big home units. Not that a home unit is "bad", just that they are usually innacurate. Seemed to be slightly older versions of either: Bionaire® Cool Mist Humidifier Tower with Permanent Filter BCM658-U or Bionaire® BCM646 Cool Mist Tower Humidifier BCM646-UM |

Re: Autofilling Humi for Walk In
Not sure how DIY you are, but you could look into building your own humidifier as well. I couldn't really tell what the Trion 707U uses to vaporize the water, but it's probably something like an Ultrasonic Fogger (Nebulizer). I've used these in Hydroponics as well. They create a fog with a droplet size of 5 microns or less, which is considered 'dry' fog. You can hold your hand in the fog and pull it out and it won't be wet.
This site has a good selection of foggers: Mainland Mart A single fogger head will run an average of around $30. I don't think a humidor humidifier would need more than that. You don't want to blast the atmosphere with water, just keep the %RH level. They sell little floats for a few bucks that will keep the fogger at the apropriate depth in the water. For a container you could use a 2 or 3 gallon cooler (I'll coin the term: Coolidifier). With that you will need a humidity switch in between the fogger and the power outlet. Something like This One for around $40. The power to the fogger will stay on until the humidity gets to your set point (70%) and then shut off. If it drops below that, the power will kick back on. From there you just need to cut a hole in the cooler and attach a small DC Fan to it. It's usually better to have the fan blowing in to the unit, rather than out, unless you have a waterproof fan. So you'd actually need to cut 2 holes in the cooler. One for Input that the fan blows into, and the fog will automatically come out of the output hole. Hook the fan up to the humidity switch as well so it only kicks on when the fogger is running. Fans can be found for less than $10 (Basically the same fans that are used to cool computer cases), and you would just need a DC power supply for it. Match up the power rating of the fan you want with a power supply (i.e. 12VDC @ 500mA). Here's an example of some power supplies: Here In all you can probably assemble everything for less than $150. The main fogger units will last for years, but the little nebulizer disks have a 6-12 month life span. If you don't use distilled water, they can burn out in less than a month. They can be replaced for a few dollars each though. That same Mainland Mart site sells the replacement teflon coated disks. Anyway, just throwing out some other options. |

Re: Autofilling Humi for Walk In
Matt,
Sounds like you have a fun project. The measurements given are 300 cubic feet. As someone suggested the Trion 707 would be overkill. It is a centripetal device, which means it makes fairly large droplets- with probably not enough room to evaporate before hitting something & soaking it. Other choices would be a simple evaporative type of humidifier with 3-5 gallon per day output. We use off the shelf humidifiers as well as custom systems & match them up to the digital Set & Forget control for tighter control (2%) of RH. Advantage is low cost & easily maintained. Can be fitted with autofill. The ultrasonic fogger is very intriguing. I am very familiar with the Habitat Ultrasonic, which can run $$$$ for a walk in, but have heard they are quite efficient. This is the first time I have seen Ultrasonic heads with reasonable output at a civilized price. I am going to order one of the larger ones just to play with. I don't have much information on which of these sizes would work best, but given the low cost, one with 3 heads & 1500ml output would be a good start. If you have a good sensitive control, higher output won't hurt you. Too small & it will never keep up or turn off. To do auto fill get a 4-5 stage R/O system, not just a filtration system. There are dissolved minerals that will trash out whatever humidifier you get in very short order with improperly treated city water. Most need to be near a drain to offload excess water. You can use the dial type analog control for humidity-they are inexpensive, but digital will allow for a tighter control of range. Most tape type dial sensors have plus-minus ranges of 4-8% and have a lot of fiddle factor to dial in. I am biased, but I would never trust an analog sensor control. I used them before digital was available & they can be a challenge to maintain tight ranges of RH. Some work well, others drift quite badly. Have fun with it. cheers, Bob Staebell |

Re: Autofilling Humi for Walk In
Thanks Bob - great info.
You actually touched on a question I was thinking of posting - why not use a filtration system as opposed to R/O or distillation? I'm thinking along the lines of Britta, etc. You mention a drain - do R/O and/or distillation systems need a drain? I figured there would just be some type of part or filter that would occasionally be replaced. There is a drain in an adjacent room, but I doubt it would be practical to run a line to it. I could just punch a hole in the exterior wall and let the water out that way, though. |

Some RO's need drains and pretty much all distillers need drains. Distillers don't boil the water all the way down when they make steam, they are left with a brine full of heavy solids and "crap" in the boiling vessel that must be disposed of. Boiling all the way down and not flushing the vessel would eventually ruin the unit due to scaling. Some RO systems use a high-pressure backflush to extend filter and membrane life, when backflushing, the contaminated discharge needs to be disposed of. |

Most distillers that I am familiar with do not have runoff. All water passes through a boiling chamber and only steam comes out which condenses into the holding container. You just take the boiling tank out and rinse it out every 6-12 months. Here in Reno running a distiller for 12 months I can fill a gallon zip-lock bag about half full with the 'sludge' that is left behind. I wouldn't put a distiller in the humidor itself though. They do generate a lot of heat. With a pump on the distiller you can run a water line in to the humidor from wherever the distiller is located. RO systems are pretty good. Most do incorporate a runoff system which have varying degrees of efficiency depending on the system. Some can be as bad as flushing 7 gallons of water down the drain for every gallon of clean water they produce. I believe you can get the same pumps for RO systems that are available on distillers, so it doesn't have to be inside the humidor itself. Usually people put them under their kitchen sinks. My only issue with RO is that it's not 100% effective at removing contaminants. Certianly better than nothing if a distiller is not available though. |
