The 200-ton water-cooled screw chiller features a twin-screw compressor, with Hanbell or Bitzer as standard options, and Refcomp available upon request. Both the evaporator and condenser utilize high-efficiency internally threaded copper tubes to ensure superior heat exchange performance. Furthermore, the materials can be customized—including the option of stainless steel shell-and-tube evaporators or titanium-tube evaporators—depending on the chiller's operating environment and whether the circulating fluid is corrosive. This 200-ton water-cooled screw chiller employs a Siemens PLC for intelligent temperature control; the control program can be custom-written to meet specific requirements and can also be integrated into a remote control system.
