FLOW-TECH Systems 

How it Works

The system generates a low frequency signal that is pulsed several thousand times per second and propagated through the entire plumbing system. FLOW-TECH is the only system on the market that maintains measurable signal strength and treatment throughout your entire plumbing system, regardless of flow.


The FLOW-TECH system generates a radio frequency signal in the 140kHz range that is introduced into the water system and creates a diminishing sine wave that randomly switches on and off up to 40,000 times per second. The system produces hundreds of billions of nucleation events per second throughout the plumbing system that remove the surface charge of suspended particles. These suspended solids become the preferred sites for precipitation  of CaCO3.


In 2009 the University of Pittsburgh conducted ASHRAE Project Number 1361-RP where they found that Pulsed-Power and all of the other tested chemical free devices were unable to control sessile or planktonic microbial growth rates. In 2012 the University of Pittsburgh repeated this test and concluded that the FLOW-TECH system successfully achieved a 98% reduction is biofilm growth.

The FLOW-TECH system creates a pure water layer along the surfaces and pipes that prevents biofilm formation and removes existing biofilm accumulation. Bacteria are encapsulated in the same powder that prevents scale formation, and the bacteria that are not encapsulated are damaged by the Flow-Tech signal and are unable to reproduce.


The FLOW-TECH system reduces corrosion by the aforementioned pure water layer and also by operating the system in an alkaline environment beyond the normal concentration of calcium carbonate. This allows the calcium carbonate to act as a natural cathodic corrosion inhibitor. By controlling bacteria, preventing scale and biofilm, and eliminating corrosive chemicals, microbial induced corrosion, under-deposit corrosion, and chemical induced corrosion are also prevented.


Charging of the ions in the water creates a positive and negative effect. Due to this the ions are attracted to the opposite charge creating clusters of ions. This affect enhances the ability of chemical flocculants to create heavier bigger flocs.

The Effect

The clusters or seed crystals flow through the system and will not accumulate on surfaces. On open loop systems they simply flow down the drain. On closed loop systems they stay clustered and circulate around the system or are removed by blow down.

Lime scale accumulation is slowly dissolved by the system. Accumulated scale is dissolved back into solution returning it to full efficiency and flow rates.

Flow and temperature change are required for this effect to act on existing lime scale. Temperature and flow greatly affect the time it takes to reverse the accumulation.

Scale formations such as silica, gypsum or phosphate cannot be dissolved however the scale formation can be eliminated or greatly reduced by the technology.

Signal Propagation 

The signal travels throughout the pipework both upstream and downstream regardless of flow. The signal splits and divides following the plumbing system providing a continuous effect.

Unlike other electronic water conditioners, FLOW-TECH provides continues protection due to the signal propagating throughout the plumbing system even without flow.  The signal splits and divides following the path of the plumbing system forward and backwards ensuring equipment is protected.
