Designed for easy maintenance, the LSWA Closed Circuit Cooler leads the industry in service friendly features. The three most critical areas for cooling tower maintenance are the basin, drive system and coil . The cold water basin is easily accessed from outside the tower via large circular access doors. All drive system components are located in the dry, entering air stream for long life and can be serviced from outside the tower. The exclusive Thermal-Pak® coil is designed for trouble free maintenance and long life straight from the factory.
