Temperature Control Vaping Overview:
Temperature Control Vaping is a technology that limits the temperature the coil is allowed to heat up to. The name temperature control is actually a misnomer because these devices lack any thermostat or temperature sensor. Mods using this technology do not sense the actual temperature of the coil but instead rely on the change in resistance as the coil is heated. When a specific resistance change is determined, the device will adjust, restrict, or cut-off the power to the coil. Many temperature controlled devices will only work with Ni-200 Nickel Coil or TI Pure Titanium wire. This is used because when compared to Kanthal or NiChrome they have a more linear relationship between resistance and temperature. As the coil heats the resistance rises since the increase in resistance is a relatively constant value based on its temperature it can use the change in resistance to roughly control temperature within 10° F.
Coils intended for use with temperature control devices are quite different from the standard coils made from Kanthal or Ni-Chrome. Temperature controlled device coils typically have many more wraps. It is quite common for a coil made from Ni-200 to use double or even triple the amount of wraps than a similar coil of the same resistance made from Kanthal or Ni-Chrome. The TC coil builds up heat quickly and requires the additional wraps to “slow it down”. For this reason there is typically even spacing between the wraps of a TC coil. Additionally it’s important to note that Ni-200 or Ti coils have very little electrical resistance altogether. Before temperature control devices Nickel or Titanium coils were not used because there was no way to safely limit the amount of electricity to them and their use would have likely have resulted in injuries and property damage.
The ability to adjust and precisely control the temperature of your vape does more than make it safer. It also allows you to further fine tune your vape to find your exact sweet spot. In fact many temperature controlled mods have a memory function that remembers the resistance of a coil in case you need to remove your atomizer for a moment but also makes it as easy as a click of a button to adjust a new coil to your previous settings ushering in a new level of convenience as well the obvious benefits of not getting any dry hits.
