United States. Indiana State University (ISU) began renovating its galvanized steel cooling towers for modern models based on engineering plastics; more energy efficient, requiring less maintenance, minimizing the cost of downtime and contributing to environmental sustainability.
According to Mark J. Pupilli, ISU's construction and facilities manager, the decision was made because the capacity of the central ice water plant was running low, so the need was identified to install an autonomous cooler that would allow the connection of the building with that central plant and thus maintain the atmosphere of all campus facilities.
"After several revisions and at the suggestion of one of our suppliers, we decided on a 550-ton tower of the Premier series from Delta Cooling Towers, Inc., which has a counterflow design, a low drop pressure, a self-propelled PVC water distribution system, a direct transmission fan powered by a fully enclosed one, a frequency inverter for energy saving; in addition to a modular construction that allows the grouping of the tower to offer a greater tonnage of cooling," added Pupilli.
Additionally, the design is relatively lightweight, UV impermeable and virtually corrosion-proof.
