" The efficiency of the AquaGen top V is up to 99% "


When the AquaGen® premium.top recombination system is used, the hydrogen and oxygen gases which evolve during water decomposition are fed into the AquaGen® recombination plugs. By means of an integral catalyst, these gases are recombined in the form of water vapour. This water vapour condenses on the sides of the AquaGen® premium.top vent plugs. The resultant drops of water flow downwards and are returned to the battery.

The efficiency of this recombination is up to 99%

Because of this level of efficiency, water refilling is drastically reduced, with even total freedom from maintenance being possible. Another benefit from the use of AquaGen® premium.top recombination plugs is a considerable reduction in the ventilation requirements according to EN 50272-2 / DIN VDE 0510 Part 2 (European standards).

Freedom from maintenance with no restrictions

hoppecke aquagen premium top V

The recombination of hydrogen and oxygen is an exothermal process in which heat is released.

With sealed batteries, this recombination takes place internally at the negative electrodes. The increased temperature in the interior of sealed batteries leads to life-reducing effects, especially at the electrodes. To minimise these negative side effects, the operation of sealed batteries is subject to various limitations.

When AquaGen® premium.top is used, the recombination does not take place at the active components (electrodes) and not within the battery.

The AquaGen® premium.top recombinator is fitted to the battery as an external component. This avoids any temperature rise inside the battery. The separation of the recombination process from the active components of the battery allows maximisation of freedom from maintenance, as for sealed batteries, without reducing life expectancy and with no restrictions on operation of the battery.



  • Integrated catalyst
  • Integrated bi-directional valve
  • Integrated flame barrier
  • Integrated absorber


  • Maintenance intervals are fully extended with even total freedom from maintenance
  • Reduction in ventilation requirements leads to cost savings for air conditioning systems
  • Efficiency maximised to the level of sealed batteries
  • No significant escape of gases or aerosols (similar to sealed batteries)
  • Reduced risk of explosion
  • Operating throughout the entire lifetime of the battery
