  • Page 3: Introduction

    HIGH-EFFICIENCY OIL SEPARATOR E YR Screw Chillers utilize high-efficiency oil sepa- ration, limiting oil carry-over to less than 500 ppm. Oil is vital in screw compressors for lubrication, rotor seal- ing and cooling.

  • Page 4: Ratings

    Program, chillers are regularly tested in strict compli- ance with this Standard. This provides an independent, third-party verification of chiller performance. YORK YR screw chillers are designed to comply with ASHRAE Standard 90.1-1999 and 90.1-2001. The su- perior part-load performance of the YORK YR chillers far exceeds the IPLV/NPLV requirements of ASHRAE 90.1, providing superior Real World Energy savings...

    The control panel is com- patible with the YORK Solid State Starter (optional), Electro-mechanical (E-M) starter, or any customer sup- plied E-M starter that complies with the YORK R-1131 standard. The locations of various chiller parameters are clearly marked and instructions for specific opera- tions are provided.
  • Page 6 This control enhancement is stan- dard on all YR chillers. The chiller can also be left in the standard control mode for temperatures ranging between 20 and 70°F (-6.7 and 21.1°C), for applications involving a process or comfort cooling duty that requires leaving chilled liquid temperature setpoint control.
