How do Arctica Tumblers work?
The idea of the vacuum insulated container has actually been around for over 100 years, but since its new found popularity in the world of travel mugs, it has left a lot of people wondering how it works. Though the technology is no secret, we at Arctica like to keep our customers informed and think our customers share our love of science. So here's a little lesson on how our double walled stainless steel tumblers work so well to keep your drinks hot and cold.
Double Walled Stainless Steel
The double walled design is probably the most important feature, next to the vacuum in the space between. As you can see in the cut away to the right, the stainless steel leaves a gap between the inner wall and outer wall. The liquid inside will only comes in direct contact with the inner wall, leaving only a small surface are around the rim of the tumbler where temperature can equalize with the ambient temperature (provided the lid is secured). By minimizing direct contact with the ambient temperature, we also minimize the amount of heat transfer, both escaping and entering the tumbler. Though this works fairly well on its own, we can reduce the amount of heat transfer even further by creating a vacuum between the inner and outer wall.
Ever wonder why space is so cold? For the most part space is an infinite vacuum, with the exception of vastly scattered stars, gas clouds, planets, astroid, comets, and the occasional blackhole. The reason however space is so cold, is due to the lack of atoms in between the aforementioned masses. Heat is produced when atoms get excited, it's this lack of atoms that makes space so cold and thankfully so. Luckily, we have a vacuum insulated barrier between us and our sun, otherwise we would all be quite uncomfortably hot with the amount of heat transfer we would experience.
These are the same principles that we use here at Arctica. We essentially create similar conditions on a much smaller scale between the inner and outer walls of our tumblers. Because there is a void between the inner and outer walls, there are not enough atoms to react to ambient and internal temperatures. This works both ways, keeping heat out to keep your drinks cold and keeping heat in to ensure your hot cocoa stays hot on a cold day.
