Galvanized steel and HDPE plastic cooling towers are built to withstand nature’s elements and are CTI certified. Both types of cooling towers have cooling capacities in the range of 10 to 500 tons. The galvanized cooling towers have an induced-draft, crossflow design that saves on fan and pump power, and the galvanized steel structure and framework offer corrosion protection. The high-density polyethylene cooling towers include forced-draft (up to 100 tons) or induced-draft (100 tons and larger) designs. These towers have a PVC water distribution system and fill material to facilitate even water distribution and high-efficiency cooling.
