What cooling tower louvers do

Air inlet louvers sit on the air intake faces of the tower. They let air in while keeping falling water inside, blocking sunlight from the fill and basin, and screening out leaves and debris. Keeping them in good condition reduces water loss, algae growth and fouling of the cooling tower fill.

When to replace air inlet louvers

  • Cracked, warped or brittle louver media
  • Water splashing out of the air inlets
  • Algae growth on the fill or in the basin
  • Debris building up inside the tower

Choosing the right louver

Louvers are sized to your tower’s air inlet openings, so every order is quoted to fit. Choose a galvanized or stainless steel frame, or a louver with an access door if you need regular entry for inspection and maintenance. Request a quote with your tower make, model and opening dimensions, and our parts team will confirm the right fit. Questions? Email parts@commercialhvacparts.com.
