How it works:
Cooling water is drawn from the Cooling Tower or Evaporative Condenser sump. Velocity, trajectory, and rotation are imparted to create opposing water streams as they leave the precision nozzles.
The water collides with tremendous kinetic energy and shear. At the core of these streams, a region of near total vacuum is created which degasses the flow.
Under these conditions, hydrodynamic cavitation occurs with intense, microscopically localized extremes of temperature, pressure, and high-energy micro-jets.
Calcium solubility is inversely proportional to water temperature. In cooling water applications, the calcium tends to drop out of solution as water temperature increases and scale is formed. Chemical treatments attempt to keep these calcium ions in solution. With VRTX, the kinetic energy released when water streams collide forces solid particles of calcium carbonate (CaCO3) from solution to form non-sticking CaCO3 colloids. These colloids attract dissolved calcium and carbonate ions, and are then filtered from the water stream.
The VRTX cavitation zone is extremely efficient in controlling or even eliminating all microorganisms. The tremendous localized temperatures and extreme fluctuations in fluid pressure within the VRTX chamber causes cell walls of microorganisms to rupture.
Within the VRTX water stream, a region of near perfect vacuum (27.5-29.5” Hg) forms which strips dissolved CO2 from the water and typically maintains the pH of water near or above 8.5. Controlling scale and bacteria also allows VRTX to eliminate corrosive chemicals in the cooling system.VRTXalso keeps equipment surfaces clean by filtering out solid particles from the cooling water.
