WSAC in world’s largest water-starved solar facility

Need to deliver colder than dry ambient auxiliary water temperatures to sustain turbine performance without using any new source of fresh water? See how Alfa Laval Niagara Wet Surface Air Cooler (WSAC®) met the challenge with a wet/dry hybrid cooling system.

日期 2017-12-13

Customer: Ivanpah Solar Generating Facility

Location: Mohave Desert, California.

Application: Auxiliary water cooler

The challenge: The need to deliver colder than dry ambient temperatures to sustain turbine performance without using any new source of fresh water.

The solution: A wet/dry hybrid cooling system was installed that limits water usage to approximately 10% of the year. The system uses recycled water from RO discharge and reclaimed water collected from mirror washing which is stored in collection tanks until needed by the WSAC system.

Advantages

  • Runs dry below 90°F, partial wet/dry from 90°F-105°F and all wet above 105°F
  • Fully cleanable coils on both unit types for ease of internal cleaning of the pressure vessel
  • Uses reclaimed water from both RO reject and mirror wash water as make-up source
  • Niagara designed, supplied and warrants the entire system with a single source of responsibility
