EVAPCO’S new and improved design is both Water and Sight Tight (WST).
• Eliminates sunlight from entering the basin, thus inhibiting algae growth and reducing chemical costs.
• Eliminates splash-out, reducing water and chemical usage.
• Framed sections allow for easy removal and easy basin access. See the WST Air Inlet Louver flyer for more information. Existing EVAPCO induced draft units (the only exceptions are the UB and FM units) can be upgraded to the WST design. In addition, EVAPCO can custom design and manufacture retrofit kits for most competitors’ induced draft units.
