Freshwater Disinfection in the Tank with Ozone – The goodguards® Tankguard

Germs and bacteria quickly become a problem in water systems where water quality cannot be guaranteed or where water stands for extended periods. A persistent biofilm often forms in the freshwater tank after only a short time. The Tankguard system is the ideal solution for RVs, boats, camping, and off-grid and onboard water systems.

Tankguard: Maximum Efficiency through Ozone Technology

The goodguards® Tankguard offers maximum durability and highly effective water disinfection. The system generates highly reactive oxygen (O₃) directly in the water using electrolysis.

Even an extremely short operating time – from approx. 10 minutes daily for a 100-liter freshwater tank – reduces the number of germs and bacteria by up to 99.99%. Control is simply done via a programmable timer, which only needs to be set once. With a service life of up to 1,000 hours, the system is an extremely long-lasting companion for your water hygiene.

Highly Effective Water Sterilization in Detail

Disinfection with ozone from electrolysis is one of the safest methods of water treatment:

  • Fast action: Bacteria, viruses, and protozoa are reliably inactivated by strong oxidation.
  • Residue-free & Taste-neutral: After the disinfection process, the ozone simply breaks down into oxygen. No chemical residues or unpleasant taste changes remain in the water.
  • Safe & Environmentally friendly: Since the process takes place directly in the tank, no storage or dosing of hazardous chemicals is necessary.
General Information Plus
  • Combination with activated carbon filter: An activated carbon filter (e.g., goodguards® Reinguard) must always be used after the ozone generator.
  • Pre-filtration for contamination: In the case of heavily contaminated inlet water, a sediment filter is also absolutely necessary as a pre-filter.
  • Safety note on installation: A prerequisite for installation is external tank ventilation. This ensures that excess ozone cannot escape into the vehicle interior.
  • Easy & quick installation: Attachment in the fresh water tank is straightforward with two robust suction cups.
  • Automated control: The system can be conveniently controlled and automated via a programmable timer.
  • Residue-free decomposition: Ozone completely decomposes back into pure oxygen after approx. 30 minutes (temperature-dependent).
  • Note on tank maintenance & residue formation: During ozone production, substances contained in the water can oxidize and flocculate as harmless by-products. These settle at the bottom of the tank and thus do not enter your drinking water. We therefore recommend thoroughly cleaning the tank once a year and emptying it via the bottom drain to remove these settled substances.
  • Maintenance for hard water: For very hard water, regular descaling with citric acid is recommended to maintain the efficiency of the electrolysis unit.
