Can anyone recommend an cool hit
tank? I can’t stand a warm hit!
That is a very open ended question. Do you rebuild? Pod system or mod? what are you looking for besides being cool? are big clouds but cool hit what you're looking for? What kind of airflow do you want? Unfortunately, I have more questions than answers to this.. but, I will try to give a brief overview.
For the most part, Electronic cigarettes require heat to generate the vapor. A resistance wire (heating wire) is wrapped around a wick (usually cotton) to heat up the e-Juice. The e-juice pretty much boils into the vapor you inhale.
If you don't like the heat,part of it, there are a few things you can do however most of them have to deal with less vapor. The most obvious is to lower the wattage of your device if you can. If you cannot, try looking for a higher resistance coil if they offer it. Both of these options will of course produce less vapor.
If you rebuild, you can look for a dual coil setup, and use higher gauge wire (thinner wire). Thinner wire tends to produce a cooler vape, but less vapor overall... having multiple small coils will generally produce a cooler vape. Typically, however, the manufacturers make multiple low gauge coils, that produce a lot of vapor, and a lot of heat as well. For those, try lowering the wattage until you find your sweet spot.
The third, is to find a device or drip tip that adds more air to the mixture. Some devices have an airflow setting. Raising the airflow and allowing more air to pass through tends to produce a cooler vape, but it mutes the flavor some. There are also drip tips that can help with that by allowing more air to pass through and mix with the vapor... this also cools it down.
One last trick, is simply getting a longer drip tip and allow the vapor to cool before you inhale it. I have a cheap e-pipe drip tip that is quite long... the vapor comes out quite cool on that, and is the best device if I want a cool vape.
The best advice is to find a tank that you can rebuild yourself and tailor the vape to YOUR liking. That is why a lot of us go into rebuildable tank atomizers. Even these are geared towards different likes. For example, I like a dense but low volume (not cloud chasing) vapor at low to medium heat. the coil I have in there is a .6 ohm and I run it at 25 watts. This is in a Fresia RTA which has a slightly restricted airflow. Most of my friends have Smok tanks that produce much more vapor, but they always say that mine tastes better.
I hope that helps, or at least helps in deciding what questions to ask. Good luck in your search.
