Cooling towers (industrial and commercial cooling)

Cooling towers in petrochemical industries, power plants, large commercial buildings, and HVAC systems are used to dissipate heat from circulating water. The body, water collection basin, and internal packings of these towers are exposed to constant moisture, anti-algae and anti-scale chemicals, and severe temperature fluctuations. The use of FRP made with vinyl ester resin (due to its exceptional resistance to corrosion and acids) or isophthalic polyester resin is the industrial standard. The manufacturing process is done by hand lay-up or automated spray-up.

The main advantage of FRP cooling towers is a service life of over 20 years without the need for painting or major repairs. This material is resistant to chlorine, dilute sulfuric acid, and alkalis, and is significantly lighter than galvanized steel towers. Additionally, the smooth internal surface reduces air flow pressure drop and increases heat exchange efficiency. Alborz Organic Materials Company supplies vinyl ester resins with heat resistance up to 120°C for the construction of industrial cooling towers.
