FS-Elliott's Triton™ line of refrigerant centrifugal compressors are designed for extended service life with fewer components and subsystems, resulting in the highest degree of reliability. Advanced mechanical and aerodynamic features offer “best-in-class” operating efficiencies. The Triton is based on a 2-stage centrifugal compressor driven through a gear increaser by a semi-hermetically sealed electric motor. The rotor assembly comprises a single pinion and shaft with two high speed impellers and is supported by precision lubricated journal and thrust bearings. State of the art backward leaning impeller design provides superior aerodynamic performance characteristics over the entire operating range of the refrigerant system.
