When Frostburg State University (FSU) had to replace a failing metal clad cooling tower, the school’s engineering team considered two options: a new air-cooled system or the purchase of another metal-clad cooling tower. Neither seemed an appealing option to replace the rusted-out unit they were struggling to maintain.
Fortunately, before signing on the dotted line, the university's facility managers became aware of engineered plastic cooling towers. Constructed of high density polyethylene (HDPE), plastic cooling towers are impervious to the caustic environmental elements that continually attack metal units. They are also unaffected by pH from water sources and even the water treatment chemicals that attack metal towers internally.
