What are the properties of the EPP material?

EPP is not polystyrene, it is exceptionally environmentally friendly, flexible and has good insulating properties. We chose EPP because the material is food safe, 100% recyclable, light weight, mega strength and energy absorbing. In addition, EPP has a very high insulating property.

How long do the Cooling Cubes keep a 5 litre barrel cold?

The Cooling Cubes keep the drinks cold for a very long time. The duration depends on how cold the drinks are placed in the Cooling Cubes, how many cooling packs are inserted and also which outside temperature is produced. In a non-scientific everyday test, we achieved an average temperature increase of 0.29 degrees per hour with the Cooling Cubes. See the cooling statistic curve.

How many cooling batteries fit and the Cooling Cubes?

The Cooling Cubes can hold up to 3 cooling batteries: one in the upper cube and two in the lower cube for extra power.

There are different suppliers who offer not only beer, but also e.g. cocktails in the 5 litre barrels. In addition there are Brausets to the beer in a barrel itself brew and we offer an empty barrel in our shop, into which you can fill purely where you have a desire. That doesn't always have to be alcohol! You can also fill it with water, juice, fanta or cola.

What is the hole in the Cooling Cubes top for?

The hole at the top of the Cooling Cube is the main part of our protected cooling system. The warm air penetrates through the hole into the barrel and thus to the beer. And to prevent the beer from warming up during tapping, a cooling battery placed under the hole ensures that the air is cooled down before it comes into contact with the beer.
