GENO-K4® – patented anti-scaling with low voltage

The alternative anti-scaling device GENO-K4® uses the gentle electrochemical procedure of low-voltage separation to reduce scale deposits. GENO-K4® ensures a high degree of anti-scaling in hot water providers and pipelines without the addition of auxiliaries such as chemicals, phosphates or regeneration salt. In the device, seed crystals of calcium are formed through the creation of an electrical charge on electrodes. These crystals are transferred to the domestic water network, and further calcium grows on them. The composition of the water remains unchanged, the calcium is removed with the outflowing water and is not deposited in the pipe system or hot water provider. The patented process is highly effective and has no harmful side effects.

Installation requirements

Observe local installation directives, general guidelines (e. g. WVU, EVU, VDE, DIN, DVGW, and/or ÖVGW or SVGW) and the technical specifications of the GENO-K4®. The installation site must be frost-proof and the system protected against chemicals, dyes, solvents and vapours. A fine filter must always be installed upstream of the system. A separate socket (230 V / 50 Hz) is required within a range of approx. 1.2 m of the system. A drain connection of at least DN 50 is required to drain off the flushing water.
