Am I crazy for considering this ?
I need to protect a steel tube ø200mm 500 mm long from condensation of moisture on its inside. I need something like 20W. I just need to raise the temperature of the tube slightly above ambient.
I have looked for heating cable, and I can find plenty that are typically used for frost protection of water pipes etc. But I dont like these.
They are typically 230V AC, and I prefer to not have high voltage at all at the location of the tube.
Also these heating cables are relatively clunky.
So I was thinking why not use 'regular' wire to make a DIY of sorts of heating.
I would use a small DIN rail transformer to get 24V AC, and then drive 2A directly into a single wire wound around the tube.
I am thinking about using high temperature wire (even though it is probably not necessary), something like HELUKABEL 25511 which is a thin 0.14mm².
I would possibly make it more efficient by wrapping isolation around the tube and heating wire.
Tell me, am I on a completely wrong path ?
Are there standards or regulations that prohibits the above idea ?
