Winter draws on (or rather wet warm weather in West Wales does)

Compressor, works fine. Don’t know how much damp you get at -4 deg?

True the colder it gets the drier the air but at say 8C I found my dessicated worked better. Until it packed up that is. I doubt they will last 20 years!

Yesterday I went up to the garage and my but puckered when I saw rust over the mill, filer, and drill press tables for the first time here. Never had the problem before, so I guess it's welcome back home to the UK. My neighbour has a strip of rubber based carpet attached to the lintel across his garage door opening, which is draped back over the roll up door to keep out most of the draft. It doesn't seem to have a negative affect on the operation of the door, so I think its time for me to do the same.

Here's a quick end view sketch.......

I'm going to pinch that idea

Currently getting over 1l a day collected by my dehumidifier (its a dessicant jobbie)

Most of the big climate controlled secure storage facilities I have visited use huge dessicant driers. They make sure the buildings are well sealed and you enter via an airlock or the running costs would be crazy.

At home I have a nice compressor type which I only use in the summer. When the aga is on humidity drops to 40% so just don't need it.

Underfloor heating cable might be worth a look as well.

Thanks John. Think I will have to have a chat with my Niece, as she has a large Iguana type lizard in a big fish tank, with I believe is heated with a similar or the same heating arrangement.

Those lizard mats ^^ are great. I've not used one for a machine, I'm in the draughty shed - cover with oil camp. But I do use one under a rubber mat to put my boots on! Always dry and warm in the mornings. Insulated from the floor with some PIR. They might be a bit weedy on a big lathe though.

Yes, one has to understand why the compressor gang quote specs for 32 Celsius and 85% humidity!! It is simply to hide the fact that below 20 Celsius the efficiency drops off alarmingly. They just do not quote any figures for 4 Celsius operation. Why? -‘cos they don’t cut the mustard at low temperatures. Good for summer use, mind.

My Meaco desiccant dehumidifiers are/were notoriously unreliable. I have three - at least two in working order at any one time with perhaps the other awaiting a dismantle to rectify the fault(s), whatever it might turn out to be. It is usually the little drive motor for the desiccant disc or something needs some lubricant. They were all cheap, as non-runners, from the net.

What tosh. It's 14 degrees here, I pour 2 litres a day out in these conditions, and the machine does that all winter. If really cold the humidistat stops it.
No I don't sell dehumidifiers

14C is still quite warm.
When you get down below 8 or so it really does drop off a lot.
Compressor types remove far more when it's warm. A dessicant has a very flat curve and removes the same amount irrespective of temperature.
I have both or did until the dessicant one died.
Both have their place.

Big difference between 8 and 32...

Up to you, I've used it for 20 odd years, it works at what I want it to do - why would I need to look anything up?
If it didn't work - fair enough. At 4 degrees, as stated - how much moisture is there to remove? So the theoretical problem doesn't present itself.
It freezes, catches any moisture in the air, melts it, I throw it out, simple. I've never had a problem with that, in 20 years.
