Variable Twin Turbo (VTT) compressors are available with nominal capacity ranges from 200-350 tons for voltage applications 380-460 Volts. These models are intended for water-cooled or evaporative cooled chiller applications and will carry the ETL and CE PED mark. They are oil-free, variable-speed, magnetic bearing centrifrual compressors. The series uses IntraFlowTM technology, a new technology for improving compressor efficiency and providing an extended stable operating range while simplifying capacity control. The models also will include newly developed control electronics capable of communicating via USB, Ethernet and wireless. Other new features include USB drive data recording, shaft speed detection, motor and drive cooling and condensation protection.
