How it works

The foundation of our concept is simple: there is incoming water, and we want to take advantage of the idea of doing a service for the environment. In return, you get cold still or carbonated water directly from the tap, without having to carry bottled water home from the store.

Let’s be honest: we all know that bottled water is not ideal. We pay nine-tenths for marketing and store logistics. The remaining part is water that has been taken from a water source not unlike the one you already have access to in your tap.

Here’s how the installation of a drinking water solution works:

We really only need two things: power and water. The power should come from a grounded 230V outlet, and the water should come from a cold-water pipe with potable water.

A ball valve (often known as Ballofix™) is installed on the cold-water pipe. This allows us to connect our equipment, which is always preceded by a water safety device. The water safety device is a unit that, with a sensor on the floor or inside the kitchen cabinet, detects water if an accident were to occur. The water safety device shuts off the water supply and, in some models, also cuts the power to the equipment.

After the water safety device, a pressure reducer is installed to ensure that the water cooler works with the correct water pressure. Now the fun part begins. One or, in some cases, two filters are installed to purify the water from particles that often aren’t visible but can affect the taste and smell. The purified water also helps keep the water cooler in good condition and gives an extra boost during carbonation.

In our water coolers, the water then flows through coils that provide a catalytic effect for the compressor’s cooling exchange. What does that mean? It means the water gets cold! Really cold. Technically, we cool the water to 10°C lower than its initial temperature when it comes from the water supply, and in Sweden, we usually have quite cold water to begin with. Of course, it won’t go below freezing, because then it wouldn’t be water anymore—it would be ice. We believe 4–8°C is a great water temperature.

When dispensing carbonated water, the cooled water in the unit is pushed into a chamber where it mixes with CO2 before coming out of the tap. Now, it’s just a fraction of a second before the water starts flowing out of the tap and into the glass you’re holding. And you can enjoy glass after glass with a clear conscience, knowing you’re not burdening the environment with bottle production or store transportation, while still enjoying equally delicious—or even better—water straight from the tap.
