FACT SHEET The Dolphin Pulsed-Powered Water Treatment of Cooling Towers Superior Performance Environmental Benefits Immediate Savings Total bacteria counts are way below any other water-treatment method (1000-2000 CFU/ml). No odor and a water clarity superior to tap water. Virtually no algae, fungus, or higher life forms on wetted surfaces. Excellent corrosion protection using natural conditions without corrosive chemicals. No encrustation of the fill, bio-debris, or fouling of the chiller. End regulatory, liability, and health-and-safety concerns with chemicals. Improve and simplify mechanical room housekeeping. Eliminate the environmental impact of blowdown, air emissions, and drift from toxic chemicals. Gain green building tax credits and reduce toxic release inventory. Eliminate biofilm as a breeding ground for microbial life and Legionella amplification. Eliminate all chemical costs. Eliminate all indirect costs of chemical addition (e.g., handling, storage, regulation). Elimination of scale and biofilm throughout the system results in greater heat transfer and lower energy costs. Significant savings of water (purchase and disposal fees). Reduced maintenance of the tower and chiller. [ view pdf ]
Prevents Mineral Scale Buildup · Controls Bacteria · Inhibits Corrosion
Operating Principle. The Dolphin produces a pulsed, time-varying, induced field inside a PVC pipe that is fit conveniently into the cooling tower's recirculating water system. The electric signal changes the way minerals in the water precipitate, totally avoiding hard-lime scale by instead producing a non-sticking mineral powder in the bulk water. This powder is readily filterable and mostly removed during normal blowdown, or it settles loosely in the cooling tower basin for easy annual removal. Bacteria are incorporated into this mineral powder and therefore leave the system by blowdown, filtration, or settling. The encapsulated bacteria cannot reproduce, thus resulting in an exceedingly low bacteria population. Water softening is not necessary with Dolphin treatment, and high cycles of concentration are usually obtainable, leading to significant water conservation.

Easy Installation The Transformer Panel can be easily mounted on any flat surface using the built-in external flanges and four mounting screws. The Coil-Pipe Assembly simply replaces an existing pipe section to complete the non-restricting, flow-through installation. Uses standard 110V or 220V electric service, depending on Dolphin model size. Specific Enhancements to Cooling Tower Systems Avoids premature system leaks by preventing microbial-induced corrosion (MIC) caused by bio-debris. Extends the operational life of cooling tower systems by maintaining an alkaline pH without chemical additives. Effortless Operational Use No moving parts. No consumable supplies. Automatically eliminates scale and bio-debris buildup from clogging valves and heat exchanger channels. Tolerates operational variables without requiring adjustments.
