Workshop Dessicant Dehumidifiers?

Post by simonm » Thu Sep 13, 2018 8:46 am

I plan to replace my dehumidifier with a desiccant model this winter.

The reason being lower temperatures. My current model struggles when the temperature drops and I have to run a heater in addition. it is a bit small in any case. I also need the machine to restart automatically after a power failure which my current compressor model does not.

Two brands, available easily, in Europe were mentioned in this thread Ruby and Trotec.

(Alex) viewtopic.php?f=11&t=56213&p=613949&hil ... nt#p613777

Any change on these recommendations ? Troctec has a number of models and the exact model Les mentions is easily available.


Edit .. title changed.

Have you tried the Boveda humidifiers (for use the guitar's body and case). They handle both humidity and dryness.

I'd love to see d'addario develop a giant refrigerator size humidipak for regulating the RH of an entire room :D

Not enough surface area for vapor exchange.

I hadn't come across dessicant humidifiers before - thanks for posting, simon.

My first thought is that it is important to assess whether the extraction rate of any particular model is sufficient for your workshop. I say that because the Ruby's published extraction rate is 5.1 to 5.5 Ltrs/day (depending on the temperature/humidity) which is on the low side compared with, say, the Mitsubishi compressor-type that I use in my cellar/basement (16 Ltrs/day).

By the way, I know you have ruled out compressor type dehumidifiers but my Mirsubishi is now 15 years old and still going strong. Mitsubishi dehumidifiers are significantly more expensive than most but they, seemingly, keep going for a great many years, are versatile, good looking and can continue operating after a power cut.

Hi Simon,

I don’t have a recommendation other than to confirm that the said dissicant doesn’t put out heat — it sounds like you have some people giving you personal experience on them so you’re probably covered! What about drainage? Do you have a drain or will you need to manually empty it?

I looked at getting one but I put in a heat pump instead since we were 100% wood stove for a while... now I run the ac at the same time as the dehumidifier which is a potent 1/2 punch against wetness.

Ah the fun of basement shops :)

Hope you’re well,

Chris

I only mention this because I misspelled it recently and learned it is with one S and two Cs - easy mistake to make.

Desiccant.

Meaco Junior 8L is the one I have been using without any trouble for the past 4 years. Very reasonably priced, too.

Thanks. That is one model I have seen advertised but your are the first with personal experience. How big a room are you using it in? I will most likely have it in a room that is approx 8'x20'.

The actual workshop is 10' x 10' approx, but I leave the door open to another slightly larger room. The building Is a 'log cabin' with 45mm thick walls. Seems to work perfectly for me, so it will surely be fine in your shop.
