Imagine a world in which dry hits and flavorless vapes were a thing of the past... What if I told you that could be a reality and that technology exists right now!? Two words sum up such a wonderful tech: Temperature Control. What is this wizardry you speak of? I’ll break it down for you.
With regular wattage mode when you fire your favorite tank or atomizer there is the possibility of supplying too much power to the coil you are using. This results in a horrible burnt, dry, nasty tasting pull off your vape. This is not at all what you want to experience, though we all have. When you take a pull using regular wattage mode, your coil can get hotter and hotter as you draw; which could lead to an undesirable experience. Your wonderful flavor you thought you were going to taste is instead replaced with the distinct flavor of cotton burning. Yum! Right? Luckily, we have temperature control to prevent that all from happening.
I’m going to jump a little bit into the science side of what temperature control is. Mainly there are four types of wire used in coils for vaping, namely, kanthal, stainless steel, nickel and titanium; kanthal being the most common. The big difference with kanthal is the resistance of the wire does not change much when the wire heats and cools, contrary to the much greater increase in the resistance when using the other three wires; that change in resistance is what temperature control monitors. It keeps track of the increase of resistance and through some of the programming on your mod it can tell you what temperature the vape is hitting at.
So, with temperature control you can set just how hot or cold you want the hit to be by setting the temperature, which in turn can affect the flavor of your vape. This gives you the control to bring out certain notes in the flavor at various temperatures that you wouldn’t be able to do otherwise.
Now what about those dry hits that we said would go away using temperature control? Ah yeah, I did say that, didn’t I? A dry hit occurs when you hit your vape and the cotton is not saturated enough, which makes the cotton burn. They’re bad, mmmkay. So, what happens on a temperature control set-up is when you activate your vape and there is not enough liquid to essentially cool the wire, there is a sharp increase in heat and resistance. The mod detects that increase in resistance and ramps down the power. That’s right, the mod detects you’re about to get a dry hit and kills the power to avoid it. When properly set up and configured, you can try to fire a totally dry coil and it will not burn the cotton! Of course, you must set the temp below the burning point of cotton.
Let’s say you like a nice warm vape. You set the temperature to 480 degrees. When the wire increases resistance enough to reach 480 degrees the mod will fluctuate the power output to keep the temperature as close to what you set it to as possible; so in the end you get consistently smooth, flavorful pulls all the time.
A few pointers when considering temp control:
Some mods will do temp control better than others. DNA mods are some of the, if not the most, accurate ones on the market.
You will need coils made of stainless steel, nickel or titanium.
If you make your own coils, DO NOT dry burn nickel coils. Stainless steel and titanium can only be very slightly heated and titanium less so than stainless steel. Pay attention to a uniform color change. Do not get them glowing red!
Spaced coils are preferred for temp control. Contact coils will retain the heat longer, throwing off the resistance.
Power settings are not as important as the temperature you want to vape at. The power supplied just means how fast you want to hit your desired temp.
