BAC | Selecting the Proper Materials of Construction for Cooling Towers
Which Material Option is Right for My Project?
Determining the appropriate material for construction for a project depends on several factors, including water quality, climate, and environmental conditions, availability of time and manpower for maintenance, unit lifetime requirements, and budget. BAC provides the widest variety of materials for construction options in the industry and has the ability to provide a solution to meet all conditions and budgets.
TriArmor® Corrosion Protection System
The TriArmor® Corrosion Protection System provides the ultimate cold water basin protection in the harshest environments. Watch this video to learn more.
1. G-235 Galvanized Steel - This heaviest commercially-available galvanized steel is universally recognized for its strength and durability. With proper maintenance and water treatment, it offers excellent service life under normal operating conditions.
2. Thermosetting Hybrid Polymer - This polymerized coating is baked onto the galvanized steel creating a durable barrier. It has been tested to withstand 6,000 hours in a 5% salt spray without blistering, chipping, or losing adhesion.
3. Polyurethane Barrier - Factory-applied, corrosion-resistant, impermeable coating creates a seamless cold water basin, preventing leaks. To ensure longevity, microscopic chains of rubber-like resin molecules permanently bond tightly with one another and the thermosetting hybrid polymer.
EVERTOUGH™ Construction
EVERTOUGH™ Construction combines a number of BAC’s innovative corrosion protection features in a single cost-effective package.
1. TriArmor® Corrosion Protection System | The TriArmor® Corrosion Protection System is the ultimate in corrosion and leak protection for the cold water basin at the best value. For over 20 years, thousands of units with the TriArmor® System have withstood the harshest environments, proving its durability and reliability
2. Corrosion Resistant Distribution System | For Series 3000 Cooling Towers, pultruded fiberglass reinforced polyester (PFRP) hot water basins provide a lightweight and high-strength alternative to conventional stainless steel with an added level of corrosion resistance. BAC’s fiberglass-reinforced panels are impervious to a wide variety of chemical and atmospheric contaminants.
3. Thermosetting Hybrid Polymer | A manufacturing process fuse bonds a hybrid polymer to heavy-gauge G-235 galvanized steel providing superior corrosion protection. Over the past 25 years, this corrosion protection system has been installed on thousands of units worldwide.
