Tired of burnt coils or the horrible taste of dry hits? Tired of burning the newly wicked coil and having to replace it? Are you annoyed that your vape is simply too hot? Temperature control might be to right solution for you! This is a relatively new technology that allows users to limit the temperature of their coils and thus prevent it from burning.
What is Temperature control?
Temperature control (TC) works by restricting your coil temperature to a preset value (°C/°F). When this feature detects the temperature is over the limit it cuts off power to it and adjusts, reduce or restricts it to prevent burning the coil.
The interesting part about this technology is it does not directly detect temperature with heat sensors, but it monitors resistance as it is heated. When there is a slight variation detected, it adjusts the power.
So what coils work with TC?
Only coils made from pure titanium (TI) and Nickel (Ni-200) wires allow temperature control as they have superconductive properties (a linear relationship of resistance with temperature). In layman’s term we can predict the temperature based on the resistance (ohms) we apply to the metal, as there is a pattern we can predict. What devices have temperature control?
In the early days this technology was in a limited number of devices due to cost. Now days, with the development of cheaper chip processors that control temperature control it is present in most mid to high end devices. Some devices we stock that have TC functionality include:
How to use temperature control?
This is a relatively easy process, the first thing to do is set your device to temperature control mode and make sure the coil you have supports this. Then lock in the base resistance of the coil, every device in doing this process so refer to your manual. That’s it!
What temperature should I select?
We all know that water boils at 100 degrees. E-liquid has 4 main components such as Vegetable Gycerin which boils at 290 degrees, Propylene Glycol at 188, Nicotine at 247 degrees and ethanol at 78 degrees. However, flavouring used are a blend of esters with varying boiling points, for example the flavor of cherry, benzaldehyde boils at 178 degrees, grape (Methyl anthranilate) at 256 degrees just to name a few. Most e-liquids manufacter have an exhaustive list of flavourings they blend to create their master pieces, hence the optimal temperature is very difficult to assess.
Common temperatures are between 200-250 degrees Celsius. Start of with a lower temperature then slowly increase it until you have your preference, every e-liquid has a different ratio of VG/PG as well as flavourings so the optimal temperature widely varies.
Pros/Cons of Temperature Control?
It can extend the life of your coil but not allowing it to burn at high temperatures that wattage mode can cause.
Some mods with temperature control can prevent dry firing and burning out the coil, as they wont fire if it detects insufficient e-liquid.
Generally, the metal (Ni and Ti) is more expensive than Kanthal and other non TC metal coils.
