BVC means bottom vertical coil, and, it differs from
the BDC, in that the BDC has dual coil configuration while the BVC has a single
coil which stands vertically. The coils
are, in principle, just wires twisted about a wick. The battery heats the coil which in turn heats
the wick. In some vertical coils, the
upright coil is surrounded with a cotton wick.
This facilitates direct airflow. The
direct airflow results in the vaporization of more e-liquid because of constant
heating along its length. Some vertical
coils also have a larger diameter that allows for additional airflow.
BVCs were initially popularized in the vaping
community by the Aspire brand – the producers of the Nautilus tanks, since
these come with a replaceable BVC for convenience’s sake. Their coils are made of stainless-steel.
Did You Know Most Vape Coils are Made of Either Kanthal, Nickel,
Stainless-Steel, or Titanium?
All coils have the resistance indicated on the device
in terms of “ohms”. Basically, the lower
your coil’s ohm, the more the vapor. Mostly, ohms range from 2.5ohms to around
1.5ohms. These heat up slower and mimics
traditional smoking best. They also make
for some cool vaping.
Some coils, however, can even go all the way to 0.6
ohms. When you use below 1ohm resistance
coils, you’re experiencing what’s known as “sub-ohm vaping”. This drains the battery faster, but also
produces more vapor.
As for the coil types:
- Nickel
coils are best for temperature control since the resistance adjustments with
nickel are predictable, resulting in stable flavor and vapor both. - Kanthal
coils can be used with high temperatures and are easy to work with, too. - Stainless-steel
coils last longer than kanthal coils and also heat up quicker. However, the resistance changes non-uniformly
when the coil is heated. - Titanium
wires also can be used, as these are best for temperature control
What are the Advantages that BVC Coils Have Over Horizontal
Coils?
Just want to first throw it out there that some
benefits such as increased flavor in BVCs are disputed. However, advantages of using the BVC coils
include the following below.
#1: Easier Draw
Vertical coils are easier to draw upon due direct
airflow. This can be attributed to the larger coil diameter exhibited by the
BVCs.
#2: Cooler Coil
Vertical coils are cooler due to the increased airflow
within the coils.
#3: More Vapor
Vertical coils produce more vapor due to the
vaporization of e-liquid
#4: More flavor
According to some more experienced vapers, bottom
vertical coils produce a higher flavor production in comparison to horizontal
coils. This under debate though, due to
the many variables involved. User bias
is also, undoubtedly, a factor.
#5: Last Longer
Vertical coils last longer in comparison to the
horizontal coil because of the increased airflow results in cooling of the
coil. With BVCs, the risk of the wick
burning caused by dry spots is also greatly reduced. Consistent e-liquid flow is an added benefit, and
you won’t get frustratingly dry hits while vaping.
Bottom Line: BVCs Can be an Awesome Option in the World of Vaping
BVCs are considered the real deal, especially amongst
a lot of different vaping communities. They
are, however, not cheaper than the dual coil configurations due to how they’re
made. The BDCs also burn through the
e-juice faster than with BVCs. Still, ot
all comes back down to individual choice, though. Do you want a direct and deeper throat hit? No? You
prefer a smoother drag with lots of vapor? It’s now all up to you.
