hair straightener heating element?

[ozexpat]

i picked up a couple of these at a good will

i had to bypass the safety switch that shuts it down if it goes off and on repeatedly. I am in test mode but looking good

Nice little heaters. 200 watts is more reasonable than some of
the elements in other small heater. This is a picture of a custom built incubator I was repairing today. (NOT ONE I BUILT) . A fellow had purchased it new recently and it promptly caught fire. He brought it to me for repairs. The best I can tell the fan stopped turning and the estimated 1500 watt heater melted the plastic housing and caught the wood cabinet on fire. The safety cut out switch may have been disabled. I know you have experience building incubators, but other should consider the possibility of fire when choosing high wattage heating elements for incubators. I install 45c thermal shutoffs switches in my incubators just in case.

I like the idea of a thermal shut off switch. I will retro them in every bator

What do you think of these

Those are the same type I use. I use the ones set at 45 c or 112 deg f. They reset after cooling down. Non resetting thermal fuses are available but typically only for much higher temps.

thanks for the advice.

I routinely put a 5 amp fuse on my line in. I am not sure people think about electrical safety. I did not think about overheating as I tend to use the lowest possible rated power sources necessary but I love the idea and will run with it.

Hi,

Nice one on the thermal fuse/switch... I'm planning on my homebuilt bator and hadn't thought on that... Thanks for the pointer.

Any advantages on using the kind mentioned by ozexpat, over this kind?... http://www.ebay.com/itm/KSD301-45C-...622?pt=LH_DefaultDomain_0&hash=item2c72bf67e6

Besides (seemingly) being cheaper, they have a higher current rating... 10 Amps over 5... Most likely wont use that much current on a bator heating element, but...

Cheers

if you are using a heat source greater than 500 watts without a relay then the other seems fine. I will retrofit all my bators so I am happy with what I have. The price for a single unit is amazing

The alternative temperature switch you are looking at would work fine. Type I use is what I am familiar with . I tested them and was satisfied with the results. Convenient to use. I cut the power wire going to the heating element and wire it in series, zip tie it to the wire bundle.

Hi,

Thanks for your feedbacks.

I was just checking for differences in behaviour (or not), because I'm not familiar with thermal fuses/switches... Think I have a couple (of the 2nd kind) in my junk box... Have to check if it's the right temperature however... Most likely not...

It's a small (48 eggs) bator and I'm fitting a 100W heating coil, repurposed from an old aquarium heater... Hope is enough... Anyway that's about 0.5 Amps on 220V, so any type will do.

Thanks.

Cheers

I like to build as well. I have an electronic, and electrical background and am currently an maintenance director, I have worked with very large and very small voltage, and amperage. I approached incubator building by keeping it simple, and safe to use, and I also tested before putting into use. I also am as cheap as they come , and like reusing stuff that still can serve a purpose. I also like techie stuff. so you see some of that in my latest build...As anyone here on this Great forum can tell you if you have a controllable heat source, and way to control humidity, you can hatch eggs. make sure you are comfortable with what ever you are trying. and test , test, test. you have to be able to trust your build to run for weeks, without failing, and without starting a fire. Good Luck with your endeavors. Phil.
