What do you think about temperature control devices?

[VictorC]

especially in light of recent studies (which might not be totally accurate).

Here is my thoughts.

At a high temperature PG/VG based liquid may produce carbonyls and it seems safer to use a temperature control device to avoid coil overheating. Just voltage / wattage readings become less relevant if you don't know the temperature of the coil.

Since VG (554 F) has a higher boiling point than PG (373 F) it's safer to use it in a coil heating device.

For example, dna 40 device allow you to set the temperature of the coil to 450F which is way less than a boiling point of glycerol (554 F) and keep it at the same level regardless of the coil resistance (sub or above ohm). Set it and forget it.

I am not an expert by any stretch, so what do you think?

It may be fine for high power vapers, if it works correctly. Seems there have been issues. Not something I would ever need.

They are the future of vaping. One of the biggest advances in vaping technology in history, arguably bigger than VW (though tied together).

 

[maxd]

it is not bad to have temp. control

does it help much - well, so far more treated as "subjective stuff", IMHO

Well said Dr.G

 

[Vapenstein]

temp control means added safety and never, ever getting a dry hit
newb or veteran, there's nothing not to like about it IMO

Someone stated much earlier during the DNA40 release: **If VW was automatic transmission - TP is cruise control**

 

[dr g]

TP is automatic crash avoidance

I cant afford to try a DNA 40 yet but i would love one.
Although most wont overheat liquids to dangerous levels on a normal mod due to the nasty taste ,this safety feature is nice and could shut up some of the bs being spread about e-cigs.
Also watching a vid from rip online with fresh dry cotton and firing the mod to see no burning is nice. Defiantly seams like the future to me, I'm not sure how good the clones are doing but once they become cheap enough i think most if not all none mech mods will have them.

This one's cheap enough

I just realized that current temperature control devices require nickel coils, which is not the safest metal

Sucks. Will stick to VW/VV mods, Kanthal coils and organic cotton wicks, for now at least

I have two DNA 40 devices. I had intended to get into nickel builds and all, but have since lost interest.

I seldom get dry hits, and when I do it means I screwed up and need to rebuild.

What a terrible, irresponsible article. Nickel metal that is not ingested poses little risk to the user. Nickel compounds are what are dangerous.

Most nickel sensitive individuals can vape nickel coils no problem because it doesn't get into the vapor.

The sad thing is you've fooled yourself into thinking kanthal is safe(r).

There is a TC device coming out with a chip called VIR. Hopefully it will work and hopefully it will be a true TC device. Meaning that it will fire automatically and consistently at the temperature you set it at. The VIR chip also has the ability to sense liquid on the coil. It will not fire if there is no liquid. It is all automatic so if there is only a little liquid at the wick/coil it will still work, but maybe not as hot as the temp you have it set to. Pretty much there will be no more dry hits if it works as intended.

VIR uses Titanium Grade 1 wire only. And that may turn many ppl off to wanting it. VIR will not work with kanthal wire. Originally it was going to work with SS wire or Ti wire. But now it is projected to only work with Ti gr1 wire. The creator of VIR is strongly against coils getting red hot saying the oxides produced from overheated coils are potentially dangerous. The VIR TC will not allow coils to get red hot.

I can't say too much about it since I don't have it yet but there is much more info out there in cyberspace if you are interested.

I have'n fooled myself into anything yet other than smoking 35 years ago. Just reading and asking questions, still new to vaping

You did not ask above. You made an irresponsible misleading statement.

Hate threads like this.

1)People that don't understand, trying to find answers and challenging the unknown to learn.
2) Know it all's that tout it as the only possible safe way to vape, which is impossible without Full understanding and proper use.

G - wonder why I get frustrated.

Maybe a few should tone it down and be helpful instead of dropping one liners that simply insult others intelligence.

A TC chip by itself is useless. It takes the knowledge to properly use it for any decent results to be reached.

By the way, until Years of data are collected on Vaping and results are clear, anything done in the Name of better vaping is simply attempted risk reduction, NOT - SAFE VAPING.

Have not seen this. I did see someone posting incorrect information and declaring something to literally cause cancer, based on a lack of understanding and knowledge. That is similar to the ANTZ attitude and is to be dealt with similarly.

Honestly, until I see what Dr. Farsalinos' study has to say I'm holding of on TC builds.

Mainly because it really isn't protecting me or most people from anything at this point. For most experienced vapers, dry hits are a non-issue and when we do TC builds, we're setting temp limits to a point where we're getting essentially the same vape we got with kanthal. So we're pretty much vaping at the same temperatures as well with no idea whether its too hot or not.

Honestly, I find TC more problematic than kanthal at this point mainly because of the ramp up and tendency of the 510 to stop making good contact. After 2 or 3 iffy builds, I've never had the firing WAY too hard issue caused by anything other than the 510 connection going bad and the device needing to be allowed to cool and be re-seated.

Most of the time you can sense it happening, the connection going funny and you get that hint of over hitting at the start of a vape. Simply unscrewing the device a little and re-screwing it fixes it. Others it just comes up out of the blue and you get hit with this massive overpowering of the coils where you go "... IS THAT!". I've had a couple coils burn because of TC over hitting.

TC is a great idea, but the implementation is deeply flawed. Mechanically the 510 connections used need much stronger springs to maintain solid connections. On the software side, if they insist on maintaining the pre-heat function, it should be impossible to hit a coil at 400% of its setting, a resistance change too far from the baseline should also cause an error.

On a coil designed to operate at 10W or under, taking a 40W hit is causing dry hits worse than any I've experienced before TC. Dry hits TC is purportedly intended to prevent. Dry hits caused not by a bad build on the end user's part, but by 510 connections not up to the task and bad software. Without the pre-heat feature, the worst anyone would ever experience is no vapor.

^TP is more about 'peace of mind'. Knowing that however I crank up my wattage (whether intentionally or by error) my build isn't going to fry.

Dry hits, How? As long as you don't have wicking issues and the feed system is working correctly - the build would remain saturated - thus vapor!

Connectivity? The same applies to our regular Kanthal builds, tho a tad seriousness is required with Ni200. As long as the wire legs are well terminalled and you don't have a finicky 510ed atty - you are good with TP. There are certain attys which should be avoided for TP builds (e.g. K4, R-91 Black, SQR, Estia to name a few) for the rest and most attys TP works just fine.
