Dehumidifier Suggestions?


Recommended Posts

I am close to completing an observatory in my garage that will measure 8'x8'x6' and would like a dehumidifier to keep everything dry. The Obsy will be well sealed and the garage is well ventilated so it shouldn't need anything very powerful. I am looking for something that will work at low temperatures (from around 1C to 5C) and be cheap to run. 

I have seen various small desiccant ones advertised that sound ideal but they have very mixed reviews. 

Be great to hear from anyone that has one that works.

Living in Scotland we have 80-100% humidity pretty much all year round.  I had thought that with plenty of ventilation my obsy would remain condensation free however, it only takes a rise in air temperature of a couple of degrees and moisture would form on the cold mount and scope and everything made of metal leading to rust.

I run my Neostar Desiccant Dehumidifier 24 hrs a day 365 days a year.  I keep it at 60% humidity and being plumbed in (hose through the obsy floor) it never requires maintenance or even looking at.  The gentle heat it outputs keeps the obsy a few degrees above ambient temperature but not so much that I have to wait for the scope to cool before use.  I can highly recommend one based on my experience.
