The material of the heat exchange coil is the most important decision when purchasing a closed circuit cooling tower. It determines the unit’s lifespan, cooling efficiency, and maintenance requirements. There are three primary materials used for these coils: 1. Galvanized Steel (HDG) This is the industry standard and most common choice due to...
