Unusual rechargeable dehumidifier
🕑 Added 2024-01-15 06:51:46 +0000 UTCBy far the most unusual part of this rather neat product is the heater. It is a very odd twist on standard technology, that allows greater heat transfer to the air.
The silica-gel cartridges seem to dry quite quickly for reuse due to the combination of heat and a low flow of air to drive the moisture out.

My experiment of an adaptor and sawn-off drink bottle flopped (literally) with the heat.

Just 3D printing a container for loose silica that fits on the ebay dehumidifier. If everything fits I'll give it a test run and then upload a link with the STLs.

I had these same heating elements many years ago, but running on 12V. They are ceramic heating elements and act like PTC’s indeed. When the airflow stops, the temperature goes up and current drops. So they are somewhat self regulating, providing some safety.

Weight of new cartridge = 515 g Weight after heating = 475 g Definitely arrived damp then! Going to put one in telescope bag.

It's already gone up a quid since I ordered it on Monday.

Just remember when you "recharge" the desiccator canister, all that moisture within the desiccator canister is expelled in to the area you are drying the desiccator canister in.

In Case anyone is looking for them it's spelt 'PREM-I-AIR' - let's get them before the Big Clive Price Hike kicks into action!

I have that exact unit. I used it to keep the humidity in my gun safe down. Mine did not come with the boot drying attachment. It worked well, just needed to remember to pull it out and let it sit on the heater about once a week.
