The high-density polyethylene cooling towers include forced- and induced-draft designs. Features include a PVC water distribution system and fill material, seamless one-piece plastic shell, jointless leak-proof sump, and an air-moving system that incorporates a fully enclosed motor to drive the fans or blower.
