There are rotary desiccant dehumidifiers that do not cool the air, but heat it.
They operate by sucking air through a part of a rotating desiccant drum then exhausting it. At another spot, they heat and blow air through the desiccant, recharging it. The heavily moisture laden air is ran through a radiator where the moisture condenses out. If you have a source of low/medium grade heat, these can operate for the cost of running a few fans.
This type works actually can operate in colder climates as they can work down to near the freezing point of water, where the cooling type cannot operate when the dew point is below the freezing point of water.
- clayrichardson 11y agoWhoa. That is cool. Where can I read more about this, and are there any designs available to peruse?
- extrapickles 11y agoThe technical term for them is adsorption dehumidifier. Here is a video of a guy tearing down a typical household unit and he explains the basics of operation: https://www.youtube.com/watch?v=mR57FhytzFk https://www.youtube.com/watch?v=mR57FhytzFk
- bb101 11y agoWe have a couple of Meaco DD8L desiccant humidifiers - they are fantastic. Quiet, efficient and they each suck a few litres of water out of the air each day.

- clayrichardson 11y agoI will definitely look into that, and probably test a commercially available model or two. If you end up beating me to it: https://github.com/openawg/openawg/pulls https://github.com/openawg/openawg/pulls
