Question about MTL vs DTL

[Alphazero]

Hello,
I know what MTL and DTL is.
But why some devices are for MTL and some for DTL?
Does it is only a question of airflow control?
If i can control airflow then it is suitable for both?
Or there are some other factors like sub ohm or else that i am unaware of

Airflow, drip tip bore, chamber size all play parts. Yes you can MTL on a DTL tank/rda by reducing airflow and using a tip with a smaller bore (I do just that) but it may not be as tight as a true MTL tank.

Yea, MTL is usually higher Ohms and less Watts, not a big cloud of vapor is produced, works better with a tighter air flow.

Low Ohm builds and coils need more power to work right, so you kick the Watts up and end up with a bigger cloud.

Personally, I like a restricted lung hit at about 55/65 Watts...usually with a .13 or .18 coil.
Good amount of vapor, but I close down the air flow some, for my taste buds the flavor pops that way.

Others like huge open air flow and 100 Watts.

Vaping is real customizable, have to find your sweet spot.

And why high ohm linked with mtl? Because you dont need much heat with restricted airflow ?
Why low ohm linked with dtl?

Mostly because of vapor production.

MTL doesn't require much vapor production to be good, so it doesn't need large low ohm coils to achieve that goal, it only needs low amounts of power to achieve an ideal vape. This simulates the amount of smoke one would expect from a cigarette.

DL vapers want more vapor production, so low ohm coils with more power put through them is ideal for that style. The lower the ohms, the more potential you have for producing more vapor, but it comes at a cost. The lower you go, the less efficient your batteries will be because it takes a lot more power to heat them up.

The greater the metal mass in the coil, the more energy used to heat it. Resistance is futile.

The lesser the metal mass in the coil, the less energy used. Resistance is still futile.

Greater air and juice flow are needed to cool a greater coil mass. Less air and juice flow are needed to cool a lower coil mass. Resistance is still futile.

Using the same wire diameter and same coil inside diameter, more wraps means more metal mass and higher resistance. So it's possible to have a 1.0 Ohm coil side by side with a 0.50 Ohm coil and the 0.50 Ohm unit would be better suited for MTL.

Using temperature control, resistance change means everything.

Agree with the others. I do both. I use more nic in mtl than dl, also. You can’t draw as much vapor mtl, so low vapor production is the purpose of those set ups. That’s why higher nic is needed. Less vapor is also better in certain circumstances, like when you require stealth.

I use mtl when I’m driving, when I’m in someone else’s house or car ( if I’m permitted to vape there).

I like dl more, really, because I get more nic faster and tend to get better flavor as well. Even though the juice has a lower nic, I inhale so much more of it.

I think it's mainly AF and with most new, drop in coil sub ohm tanks, you simply cannot close down the AF enough to obtain a true mtl vape. Even if you can close down the main afc, there is still a large af diameter hole in the coils and under the coil and it's just not the same as a true mtl set up. Now with a true mtl set up, being less air being able to get to coil, you simply cannot go to high with wattages because there is not enough air to cool the coil. When you vape at really high wattages, you need a lot of air. With a lot of air, one needs to change from mtl to dtl in order to draw vapor

These are some great answers above.

It's all about balance. Air flow, coil mass, liquid supply and efficient use of chamber space all need to be in balance to obtain an enjoyable vaping experience. If you stay inside the parameters given by a particular device+build you'll likely get the best results. Airflow is just one of them.

It's been pretty well covered, but to put it into perspective for your situation:

With DL, you'd have higher coil metal mass (which usually means lower resistance, but not necessarily) and more air flow.

With MTL, you'd want lower metal mass and less air flow.

DL tanks often have too much airflow even at their lowest setting for MTL. DL-style airflow would tend to overcool a smaller MTL coil, so you probably wouldn't get a very good vape. An MTL tank, even with the airflow fully open, won't usually provide enough air for good DL vaping.

I think there are some tanks that can do MTL and DL, but the sacrifice is that they don't do either very well. Tanks dedicated to one or the other tend to give you a much better vape.

Note the prevalence of "usually" and "tend to" in this post. I'm quite sure there are exceptions to everything.

I have not found huge success with converting a Very subohm vape setup to MTL. Often the coils won't support it and the airflow, drip tip and just overall function of the mod seem to not work so well. If you want a crossover tank, the Crown Uwell (original) is probably your best bet, and has a 1.2 MTL coil.

I generally recommend getting a dedicated MTL vape setup if you want to try it. Tanks can be pretty inexpensive, you can probably get a Nautlus 2 for under $20 these days, etc. I'm not saying go with the N2 (although it's not a bad starting point) I'm just pointing out that MTL tanks can be pretty inexpensive and would probably provide a better experience.

There are some "crossover" tanks, usually in about the 0.5ish range, where you can open or close the airflow and the tanks have the capacity to go higher in ohms, while still being "slightly" subohm. Or you could try the Innoken Zenith with the 0.8 coil. Folks are reporting it to be a pretty nice vape, and with good cloud production, etc.

Best of luck deciding.

Due to health concerns, i want to vape only in TC mode. Searching for mtl tc mode like juul
Juul is great but they dont disclosed the max temperature...

Atomizers are fundamentally designed for purpose, inside and out !.

Trying to turn a direct to lung atomizer into a mouth to lung atomizer is the same as trying to turn a mouth to lung atomizer into a direct to lung atomizer. You may think you come close when you tweak a direct to lung atomizer, but it just doesn't cut it !. May as well be trying to MTL on an RDA.

I haven't had a lot of success finding a good factory TC setup for MTL. I looked for a while about a year ago, but I quickly decided that I'd have more luck with an RTA. There are a number of great MTL RTAs if you're interested in building your own coils. Just use SS316 instead of kanthal and you're good for TC. Building isn't as hard as you might think.

I've just remembered that there's a TC coil for Aspire's Triton Mini. I don't think the Triton Mini is widely available anymore, but the coils are compatible with the Nautilus line. The coil's 0.15 ohms but since you're controlling the temperature and the Nautilus/Triton Mini are set up for MTL, you should be able to get a decent TC MTL vape from it. Just remember never to use the coil in power mode - nickel is TC only.

I disagree. It is true, you cannot use a MTL specific tank for DL because even fully open the airflow is still going to be way to tight. However, on many DL tanks (ones with 510 drip tips) you can cut the airflow as low as you want and use a restricted drip tip and have a quite good MTL experience. This will not be the case with tank that use the really large 808/Goon style drip tips. Those are going to be DL only.

I do that DAILY on my Hadaly and Entheon clones.

 

[vapdivrr]

You might be correct, as I haven't really tried a lot of dtl tanks , trying to get a mtl vape, but I tried a couple rta's that were kind of for both and imo they just didn't cut it. I guess it depends on what mtl vape your use to. Those didn't work for me and perhaps the reason was the large hole under the coil. Yes the main af could be tightened down, but because of the larger bore under the coil, it just felt washed out compared to a true mtl tank...so I guess it's just what one considers mtl, if one started on dtl vaping and then switched to mtl, then maybe your right, but if one is a true mtl vapor who has been vaping for years, then I'm not so sure

I have a three of the Kanger mini and nano tanks.
You can get coils that fit all the way from 1.8 down to I believe .3. For MTL I do 1.8 tight draw, standard tip, for dtl .5 with a wide bore tip, air flow open all the way.
Sounds pretty versatile but of course you have to use different nic levels for each which means different juice.
You probably don't want to exceed 6mg nic on DTL.
Unless you don't use nic or can live with low on either.
I mostly do MTL but will switch to DTL late in the evening.

There are RDAs that were designed for MTL.
