Rather than a heating coil perched on top a thin tube (that was prone to movement and leaking), the Nova features a very thick center post that terminates not in a heating coil, but a 510 threaded female connector.
That connector is designed to receive the special atomizer heads. These heads are the distinguishing feature of the Vivi nova. The idea is that you can easily swap out a bad atomizer for a good one quickly.
Or, if you’re indecisive, you can easily swap out the coil heads. The clearomizer comes with three heads each with a same resistance, 2.8Ω
The atomizer head simply screws into the post attached to the bottom cap of the Nova. The atomizers have four wicks sticking out. Oddly, one of the four wicks just sits on top of the atomizer rather than running through the heating coils like the other two.
Holding all that in place is a small metal washer and silicone cover. When the top is screwed on the device it forms a seal with the silicone cap of the atomizer preventing e-liquid from seeping into the assembly.
Each set Vivi Nova V2 Tank Clearomizer includes:
1pc Vivi Nova tank - Steel chrome top and bottom caps with clear tube
1pc delrin drip tip - black
3pcs Vivi Nova replacement coil head, 2.8 ohm each.
