Water safety comes naturally
with Tank- O3



100% Natural

Environmentally friendly

How it works

Tank- O3 is a small built-in system for inside your clean water tank. Oxygen (O2) is converted into ozone (O3). through electrolysis. Since ozone is an extremely strong, odourless, tasteless and non-hazardous oxidant, Tank- O3 ensures that water in the clean water tank, but also the clean water tank itself, remains completely germ-free. Tank- O3 kills all bacteria, viruses, fungi, spores and ensures that the water tank remains completely biofilm-free. This is a unique feature that no other system can offer.

See introduction video at the bottom of this page!


What many people do not realize is that the quality of water in the clean water tank, particularly at higher temperatures, rapidly deteriorates. This leads to water contamination, a filthy tank and, in the worst case, an increased safety risk of legionella contamination. Tank- O3 is safe, environmentally friendly and 100% natural. Tank- O3 makes your life easier.

At the start of the season you rinse the clean water tank thoroughly, switch on the Tank- O3 system and then you are all set for the remainder of the season. You only have to top up the water now and then. There is no need to think about regularly adding environmentally harmful agents any longer, because your clean water tank and water always stays completely clean. An extra advantage: at the end of the season or when you are not using the camper for a while, let the water drain. From now on, you always store your camper with a clean, empty water tank. Thus you will always start the new season or after a long time with a clean water tank. That is why Tank-03 is better for you and the environment!

Assembly & Maintenance

Tank-O3 can be easily installed in your clean water tank by a handyman with a bit of technical knowledge. However, we recommend that you have Tank- O3 installed by the dealer or maintenance company of your recreational vehicle. They have the right tools and know-how.  A tank-O3 package always includes an installation manual, the installation is self-explanatory.

The system is very maintenance-friendly. This is because ozone, in addition to water purification, keeps the entire inside of the clean water tank including the top, completely clean. Your water tank will be and will remain as good as new without you having to do anything!

NOTE: the water tank must have unrestricted airflow, both in and out, so that released ozone gas can escape which dissolves directly in the ambient air. For more information see frequently asked questions.
