Materials
For the production of the heating coil you need wire. For this purpose, you can use either Kanthal or nickel/chrome wire. Even though the wire is available in diameters of different thicknesses, the thicknesses 0.16 and 0.20 are predominantly used for vaporizer coiling. Which wire you need depends primarily on what resistance you want to achieve. The larger the diameter of the wire, the lower the resistance and the more windings you need to achieve the desired value.
This is due to the mass of the wire. If it is thicker, there are significantly more electrons inside than in a comparably long piece of thin wire. The current flows through it faster, and the resistance is lower. So you need more windings (and therefore a longer piece) than with the thin wire. The thicker wire has a larger surface area than the thin wire and can therefore vaporize more liquid, resulting in an increased amount of vapor and often a more intense flavor experience.
The wick feeds the heating coil the liquid and can be made of different materials. The classic for self-winders is fiberglass: This absorbs a lot of liquid, but begins to coagulate when the liquid tank is empty. With a stainless steel screen (ESS) you can wind inexpensively and very effectively. The material has an excellent storage function due to the fine structure, and the very good vapor and flavor development convinces. Silicate cord is the somewhat more expensive alternative to fiberglass and is therefore mostly preferred by skilled professionals. It has the distinct advantage of being able to withstand high temperatures and is not likely to coagulate.
What is a Rebuildable Atomizer (RBA)?
RBA refers to a special variation of an evaporator head. This is a vaporizer head where the user can/must install the heating coil and carrier material themselves and which is used instead of a prefabricated vaporizer head.
What is a Rebuildable Dripping Tank Atomizer (RDTA)?
RDTAs are tanks that are basically a dripper with a tank. Most of the time, the tank unit is located under the vaporizer part, but it can also be located above it. Compared to normal tank vaporizers, RDTAs also always have air flowing directly to the coil from the side. Technically, an RDTA vaporizer is therefore a normal RTA, with the difference that the heating coil is not in or under the tank, but outside of it.
