What is Temperature Controlled Vaping? How does it work and why do I need it?
If you are reading this, you’ve probably heard the term “Temperature Controlled Vaping” thrown around here and there. The basic concept is that your device can be set to output a specific temperature. But how does it work?
Resistance is defined as a material’s opposition to the flow of electric current. The lower the resistance, the more easily it can flow. It’s the movement of electricity through the material that causes heat. Kanthal was specifically designed to get hot when electricity moves through it, but durable so that it won’t break down easily. Something you might not know is that when materials heat up, their resistance changes. In general, metals will increase in resistance when they are heated.
So why doesn’t your mod jump from 1.2Ω to 3.0Ω when you hit it? Because another property of kanthal is that it has a low Temperature Coefficient, which is a fancy way of saying that it’s resistance change is very small when heated. You’d have to heat it to about 900°F to see any real change. That’s way hotter than anything I’d want to vape, yeouch! This is what makes it great for furnaces and the like. So how does this relate to temperature control?
Well, the smart folks over at Evolve (who first pioneered the technology with the DNA 40 chip) realized that if you track the change in resistance internally many times per second, you can effectively determine how hot the material has become, provided you know the properties of the metal and the starting temperature (i.e. room temperature). But how can you track Kanthal’s temperature if it’s resistance doesn’t change much?
This is a problem Innokin has apparently fixed with their Disruptor TC coming out later this year. Prior to that, however, their solution was to use a different metal. Nickel has a high temperature coefficient, meaning its resistance changes drastically when it’s heated. When you use nickel for your coil, you tell your device the starting resistance. It stores this number and assumes your coil is room temperature (this is important for the technology to function properly). After that, you tell it what temperature you would like to vape at. As the coil heats up, the resistance changes and the device says, “Okay, the resistance has changed by .02Ω, the coil must be X temperature now.” Then it adjusts the power up or down until it reaches what it has calculated to be your desired temperature output. It does this very quickly to constantly fluctuate the power and maintain a consistent temperature (or more accurately, it’s maintaining a consistent resistance that it believes will produce the temperature you’ve set).
Now that we have that out of the way, there’s only one more question to answer: Why do you need it? There are several advantages to temperature control. The main one being that you can set it to below the point at which the cotton would burn, meaning no more dry hits. Once your wick starts to go dry, the temperature output is much higher and it will reach the temp you’ve set it to, almost instantly causing it to cut off. When you get no vapor from a draw like that, that’s your queue you’re out of juice. As we know, bad stuff can come out when things start burning and nobody wants that.
So not only do you get the benefit of never having to taste the armpit of satan that is dry hits, you know that you’re not burning your cotton and producing harmful chemicals. Another benefit is that flavor’s taste change at different temperatures. You might notice with kanthal that one hit can taste different from the next due to the coil being preheated when you go for that 2nd or 3rd draw. With TC you can eventually determine the exact temperature you enjoy the flavor most at and get that experience every draw. You can even share this more easily with other people. On a non-temp control device you’d have to say “Hawk sauce is best on 26g 2mmØ dual micro coils at 30w.” Think Hawk Sauce is best at 450°F? You won’t have to trip over your tongue to let other people know when they try it and you can be sure they taste what you do.
