Ocean Pointe Case Study
DATA SUMMARY:
66% reduction in blowdown, a significant reduction in chemical consumption, and excellent control
OVERVIEW
Ocean Pointe is a 30,500 square foot, three story office building in San Diego, CA. The cooling system consists of a 125-ton fluid cooler and a closed loop that provides comfort cooling to the office tenants in the building.
Before Capture H2O took over the water treatment program at this building, the fluid cooler’s copper tube bundles were caked with scale which lead to increased energy consumption due to the inhibited heat transfer. Note that every eggshell’s width of scale leads to 12% energy loss.
OUR SOLUTION
Ownership opted into the Capture H2O Hybrid Program. This program utilizes an energized physical water conditioner paired with limited solid chemicals. The physical water conditioner acts like a transformer, introducing an electromagnetic field into the condenser water. This field interrupts the scale formation process and removes existing scale by charging the scaling minerals. This results in them attracting to each other instead of the system equipment. Since 2022, Ocean Pointe has realized the following benefits:
1. Existing scale buildup that was caked on the tube bundle was dissolved after 5 months.
2. Bacteria growth, measured by ATP tests, has had an average of 0.94 rlus with a maximum of 5 rlus and zero positive Legionella tests, well within the control range.
3. An environment has been created that controls corrosion for the galvanized, mild steel and copper metals in the system while feeding zero corrosion inhibitors.
4. Cycles of Concentration have hit six cycles, reducing water consumption by 33% and reducing wastewater by 66%.

1 fluid cooler providing comfort cooling to office tenants
DATA SUMMARY:
66% reduction in blowdown, a significant reduction in chemical consumption, and excellent control
SUMMARY
The Capture H2O Hybrid Program is a great option for smaller towers and sites that have footprint limitations. It is also a great alternative to the High Cycle Program for customers who are in areas with stringent limits on softener waste generation. At Ocean Pointe, the program has led to a 66% reduction in blowdown, a significant reduction in chemical consumption, and excellent control.
