A hybrid cooling system will help customers address water and energy challenges in facilities through more efficient cooling tower operations.

Developed by Johnson Controls, BlueStream utilizes thermosyphon hybrid cooling, which reduces water consumption in traditional cooling tower systems by 25 to 80 percent compared to all-evaporative heat rejection systems. It also maintains peak process output and energy efficiency on the hottest summer days.

According to Johnson Controls, the system offers a cost-effective way to reduce water use while simultaneously reducing operating costs in heat rejection systems. The company worked with the Electric Power Research Institute to evaluate BlueStream in a wide range of cooling conditions in thermoelectric power plants. The project demonstrated the system’s ability to reduce annual water use in plants while maintaining peak plant output on the hottest days.
