Installer of The Top Gun System, the pool operator's friend and "cockpit":

Total Disinfection System

 

• The Solution as the Sodium Hypochlorite (12%) feed

• The Solution X-2 as the Hydrochloric Acid (15 – 31%) feeder, and/or Sodium Hypochlorite feed for smaller pools.

• CO₂ feeder (30 – 200 scfh capacity and 0 – 30 scfh for smaller pools or SPAs)

• Aux Venturi / eductor feed for carbon dioxide feed.

• Aux Venturi feed for ancillary chemicals (sequestering agents, enzyme, algaecides, enhancers, etc.)

• Aux line for flowcell loop.

• Sink and faucet for water sample.

• Interlocks with chemical and backwash controllers (and any other safety interlocks, such as flood protection, phase monitors, etc.).

• Pentair Intelliflo booster pump, with four preset settings (230 VAC, 20 amp circuit) – some applications may require the use of Pentair Whisperflo ¾ HP pump, if the power supply is limited to single phase 120 VAC – 208 VAC.

• Labcock and hose connections for easy access and cleaning of chemical lines and water usage for cleaning.

• Chemical shot feeder (typical 4” piping with 20 lb. capacity).

• Chemical Level Indicator for bulk chemical tanks.

• Constructed with PVC Schedule 80 and Clear pipe components, check valves, Y-strainers, True-Union ball valves, stainless steel liquid filled pressure gauges, all plastic clamps and stainless steel screws, Viton gaskets and valve kits, etc.

• All components are corrosion proof, NSF approved, UL Listed and approved by the Health Department.

• Installation includes ONE YEAR of full service, adjusting for peak performance.

Chemical Cost for 765,000 gallon outdoor pool and Annual Savings From $70.02 per 1,000 gallons, per year, to $37.38 per 1,000 gallons, per year 46.60% Savings of $32.64 per 1,000 gallons of pool water, per year

 

q       The Annual Cost is based on three months of winter usage, open season and the same bather load average, in order to create a base for minimum savings.

q       The actual savings factor will be much higher, considering the increasing cost of bulk chemicals, as well as the increased chlorine and related chemical usage in the summer, with an increased demand for acid or CO₂ usage (for lowering the pH).

q       CO₂ raises Total Alkalinity, while lowering pH. The Acid feed rate for the pool used in the Study was lowered from 8 GPH to 3 GPH. The goal was to maintain TA closer to 90 – 100 ppm (instead of 80 ppm) and pH at 7.4 or lower (instead of 7.5 or higher), based on constant water temperature of 81 deg F, Calcium Hardness of 200 – 400 ppm, TDS of 2,000 – 6,000 ppm and no Cyanuric Acid (stabilizer).

q       Chlorine savings are accounted for in the increased percentage of chlorine effectiveness from lowering the pH setpoint. The amount of Hypochlorous Acid produced by the Sodium Hypochlorite chlorine is increased from 50.25% at a pH of 7.5, to 55.5% at a pH of 7.4 (7.2 pH = 66% and 7.6 = 45%), an overall increase of over 10%, making it possible to achieve the same ORP (HRR or mV) reading and disinfection potential with less chlorine, statistically shown to be with about one third less Sodium Hypochlorite.

q       There is no change in the Saturation index (LSI), as the increase in alkalinity is offset by lowering the pH.

q       The TDS level is maintained lower, with the decrease in chlorine usage and the elimination of Sodium Bicarbonate usage for Total Alkalinity. Less water dilution or pool draining, downtime for draining, cost of initial chemical treatment and re-heating the pool, etc.

q       CO₂ usage will prevent accidental pH lowering, as Carbonic Acid cannot drop the pH of the pool below 6.5.

q       pH of water at the point of contact with the pool plaster is mild when using CO₂, with little or no effect on the plaster finish, as compared to normal acid feed concentrations that damage the pool plaster around return inlet fittings, extending the life of the pool plaster by at least two years or more.

q       The Aux feeder and chemical shot feeder enable chemical feed while the pool is in use, independent of pool activities, making it possible to distribute chemicals proportionally into the pool, through the return inlet fittings.
