Should these little 100cc absorbers warm up when exposed to air?

I have not noticed them warming up. I usually put them in a vacuum zip lock type of storage bag right away. If you leave them out too long they will be unable to absorb oxygen in a closed environment.

I don't think so.... also I would read the manual (if available, if not google it) to see how hot these get. I would not think it would be a good idea. Just my guess....

Definitely not. I use them in windy, 60's they are not thermal or thick enough.

What temperature are we talking about? I would not leave them out in direct sunlight at 100F.

Yes but observe the minimum distances to combustibles. These things get hot.

They start heating up the second they are exposed to air so you only have a short time to get them in place. Humidity does not have anything to do with their reaction only oxygen in the air.

Mine are used under cabinets. they are slightly warm to the touch . I think you may have problems with them getting wet from frost melting on them

I have these installed in a motorhome. I dont use them a lot but after a year they work fine. I dont know how well they would hold up being outside with the humidity.

These generate a good amount of heat. If you're putting them in a waterproof fixture, you need to make sure they don't overheat considering the sealed container. I would think it is best to verify with the manufacturer.

most of the heat comes from the tubes... and they are in the open. I wouldn't touch them after it has been on for a while.. they are very hot.

Yes. If you check the control unit from time to time you'll see it's sometimes hot and sometimes just a little warm. This is how they work...when they work. You'll be fine!

I've not noticed but I only had them during this winter (cold). There's no reflective coating so I'm guessing they wouldn't keep the heat out. I'm assuming you're referring to something like a windshield reflector that covers the entire full windshield. Even if they were reflective they're not big enough to cover the entire windshield.

They do heat up, if you wamted to put them behind glass or something that would probably still be safe

I haven't really noticed them getting warm but like many things electronic, I would imagine they could possibly get slightly warm. They certainly have not gotten warm enough to attract my attention. I currently have one programmable one and 5 that are not programmable. I am thinking about replacing 4 more.

Strictly UV, not a source of heat for the enclosure. They might get a little warm, but they are not to hot to touch or anything even when they have been running for hours.

I think so they do get extremely hot so you might have to hold them up a little. I've never tried it.
