Customer: Chuck Lenzie Generating Station
Location: North Las Vegas, Nevada
Application: Auxiliary cooling
The challenge: Cooling the closed loop auxiliary water while conserving makeup water based on allowed annual estimates of maximum water availability.
The solution: Considering annual weather data and water availability it was decided to design a wet/dry system to operate dry below 80ºF ambient and wet/dry above 80ºF ambient to achieve the site water limitations. The resulting solution reduced the site’s water consumption to only seven percent of a conventional water only solution.
Alfa Laval Wet Surface Air Coolers (WSAC®) are custom built, closed-loop cooling and condensing systems that combine high performance, low operating costs, compact size and reliable operation.
- Ability to achieve the aux cooling water temperature needed even at the hottest summer periods of over 100ºF ambient while still staying within the extreme water limitations.
- Simultaneous design of both the wet and dry side of the system.
