Designed for easy maintenance, the ATW Closed Circuit Cooler leads the industry in service friendly features. The three most critical areas for closed circuit cooler maintenance are the basin, drive system, and coil. The ATW basin section is designed to allow quick and easy access from outside the cooler. Just like the basin, all service to the drive system can be safely performed from the side of the cooler, and EVAPCO’s Power-Band drive system is the easiest belt drive system to maintain in the industry! The exclusive Thermal-Pak® Coil is designed for trouble-free maintenance and long life straight from the factory.
